Hi welcome to Tear Down! Tuesday Why am I wearing an Apple t-shirt I Hear you ask? I'm not an Apple Fanboy but I am a fanboy of old vintage computers and we love a vintage computer. tear down here on the Eev Vog. So today I've got classic. it's not that light classic Macintosh SE computer from the late 80s.

Let's check it out. And yes folks, this is a genuine Apple t-shirt direct from someone who works at the headquarters in the USA One of my viewers thank you very much! So this is the Macintosh SE model. It's I believe two models up from the original Macintosh It started out as the original Mac then it went the Mac plus and then it went the Mac SE I'm sure the Fanboys will correct me if I'm wrong. It's the Model 510 with the 1 Meg of memory and the 20 meg built-in hard drive.

Now this one, uh, the original Mac came out in 84. This one came out in 87 and was discontinued in about 1990. So um, it should be anywhere in that vintage. I'm not sure exactly.

uh, what year it is. let's hope it's 1980s cuz I Love the 80s Brilliant classic ma Macintosh uh Form factor 9 in screen, massive 512x 384 resolution, monochrome black and white display. none this color rubbish. Um and the max went with the Uh White display instead of the more common Uh green or Amber what at the time that were used on um PCS and other um, well, other personal computers around at that age.

And as you probably know, the Macintosh runs on the classic Uh Motorola 68,000 processor, which is, heck, it's still even used today. In some things, it is an absolute vintage processor that was used in a whole range of machines. It runs at a whopping 7.8 or 8 MHz something like that. This thing 3900 us originally with the 20 meg whoin 20 meg built-in hard drive, which this one has got it now I'm not sure if this one actually works.

it is, uh, supposed to. so we'll find out after the tear down because you know what we say here on the Eev blog. Don't turn it on, take it apart, and here it is. As you can see, it's uh, quite well.

It's a relatively small, uh, compact unit. It weighs about uh, 7.8 kilos or something like that. We'll take a good look at the various ports on the thing in a minute and uh, it's a classic Macintosh shape of course and but you can see that it's all yellowed. You can see that it had a sticker up the uh top here and a bit of a sticker on here which is peeled off and it's all yellowed.

And this is, um, a very common for vintage electronics like this because that's the, um, uh, the bromide in the plastic. Um, actually, uh, you know, leeches, um out of the thing over time and with uh UV exposure and uh, stuff like that. So um, that bromite is used in the flame retardant in the plastic in these things. so very common for these things to turn yellow.

You can get some um, hydrogen, uh peroxide, I think and various other techniques to get the yellow out of this. but yeah, it's got that classic vintage yellow look and yep, classic vintage computer smell. Love it. And on the front here we' got some uh vent ports there.

we've got a 3 and 1/2 in uh floppy on this thing uh Power led up there, the Apple logo Macintosh SE and underneath here we have a uh um screen brightness adjustment control but that's it for the front and we'll take a look at the ports on the back. Here we have on the left side two um Apple desktop bus uh ports and uh, that was supposedly um the protocol and the Uh interface for that was designed by the was himself. beautiful, good on your was and uh, this Db19 connector here, um that is a disc drive, uh interface port and this uh Db25 here is not a Serial interface or anything that's actually a Scuzzy port. And then we have uh two serial uh, one one for the serial printer and one for the serial uh modem, serial coms and uh audio output and there's the label on it.

minosh SE It's got 1 MB of ram, an 800k, 3 and 1/2 in drive, and a 20 meg scuzzy hard drive. Beautiful and made in the United States of America Beautiful. and the model number is M50 11 um you Auto switching power supply blah blah blah blah blah FCC ID blah blah blah blah blah. But there you go.

Um, we've got a fan on the back here and that's about all she wrote. It looks like we have a lockin mechanism here that looks like you know you put it in so that nobody steals your little Mac. And we've got the original uh keyboard here. there's the Apple logo, it's got the Apple uh desktop bus connector on both sides there, so that's a really good uh design decision so that you can, uh, plug it in either side and you can plug your uh Mouse into um, the side of the keyboard or into the back of the unit.

Really quite neat. I Like it and it is the Apple keyboard 2 Apple Computer Ink and that's the uh, the family number m 0487 for those playing along at home. Copyright 1990 Apple Computer Ink. So there you go.

If this one's uh, 1990, then this could be a 1990 vintage computer assembled in Taiwan not in the US. It's got a couple of little flip out feet here and uh, couple of little rubber uh slide Stoppers down there and it does feel quite uh, heavy and uh, you know the response is a little bit soft and spongy, but uh, it's not a big keyboard and we have an original Apple Mouse with this thing too. Yeah, none of this. Optical rubbish.

It's got a real mousy ball in there and that is the Apple desktop bus Mouse family number. it's a revb PCB It's got a Logitech uh branded Uh custom chip in there and date code 8946 There you go 2N 3904 transistors and a few passive stuffs and you can see the optical uh encoder wheel down there for the x-axis as I move the mouse back and forth. There you go. That's how they used to work before the optical uh mice these days, which uh, you know, take an image of the surface that you're rolling ing on.

No, they did them with a wheel and some photo, some uh leads and photo transistors there to uh, interrupt. uh every time it it passes through, the light passes through one of those slits. You can easily get the direction and of course we have one for the y direction as well. And in the keyboard here, there's uh, nothing much happening.

There's a large 40 pin dip which is uh, manufactured by National Semiconductor, but it says copyright Apple uh, 1990. It's a um yeah 8048 which is a uh Classic Controller chip used in all sorts of stuff. We got an inductor up here and uh, weird looking inductor but it is um right next to the Apple desktop bus and another one over here near the other desktop bus and there's a metal plate under there which they've earthed down in there. couple of flat flexs going over to the cable, but eh, nothing that exciting.

Does have a reset button though. Tada So the 8048 uh used in this thing is, uh, actually a, uh, just you. You know, a general purpose micro? uh, microcontroller. but uh, they do seem to be, uh, very, um, widely used in keyboards back in the uh, 80s, that's for sure.

and U probably still even today. Maybe if you could still, you know, or well into the '90s or maybe early, uh, 2000 keyboards. But uh, it's interesting that they have this reset, uh, switch up here I You know I don't know another keyboard that actually has a reset switch on it? Maybe it's some uh Quirk to do with the Apple desk top bus or something? I Don't know. Now there's one thing I do like about this.

Mac is the big carry handle on the top here. it's big, it's deep, and you can really get your hand right up under there. and just you know, throw this thing around and you know you don't have any real real fear of, uh, dropping the thing. It's really quite nice.

So folks, it is tear down time. Now this thing. um, it's got two Torx screws on the back here, but it looks like the other torque screws are. You probably can't see it, but they are embedded way way down deep in there and uh I'm not sure if I have a Torx screwdriver long enough to get to it.

So just a regular uh, torque screwdriver like this, it really doesn't quite get in there because it just gets jammed on the case and the it's all too big. So another option. Now this one looks like it's going to do the business, but as it turns out, this top part of the shaft here that holds the magnetic bit in place is just slightly too wide and it just gets a bit jammed in there and doesn't really doesn't really work. So turns out I've got an extender piece here for it and uh, that one is slightly thinner than that one and hi can I get that to lock into place? There we go and I think we have it.

it's coming out not sure how far out to turn it. Taada, it's out self Tapper and uh I believe that's probably it. Four screws on the thing I'm assuming there we go and hopefully the case will just just, uh, sort of lift off. I'm not sure though.

Oh, there's one thing I wanted to show you is the bottom plate on this thing. Let's I probably should have left those screws in. Actually, check this out. It looks like somebody's actually installed a custom plate on this thing.

It looks like it's stuck down with double-sided tape on there which is really, uh, really, quite weird. double-sided tape And and then there's this plate on the back and then it's got these little uh, screw sort of feet on the bottom of it and I'm not sure and sort of these little things and I'm not sure actually what's going on there I'm tempted to to rip the whole thing off, but uh, couldn't be bothered. Let's open the case. So I've got the screws out now.

what? I guess um, it might have some uh, plastic PES around the outside? I'm assuming. so yeah, let me work on it. No, it looks like it just needed a bit of gentle persuasion there to sort of lever it out. It was just a bit, uh, crusty and stuck together over all those years.

So so it looks like maybe yeah, I can see CRT is attached to the front. You can see that that's not coming out. so I'm assuming that that is back case. Well yeah, the back case is just going to lift off.

so if I put that down Tada Oh there it is. Ah, look at that thing of beauty. And for those who are curious about the uh, famous signatures on the inside of the case, Yep they're all there. Check it out and there folks is Steve Jobs Tada and that's done by rule engravers Incorporated They do mold texture in beautiful Illinois And here we have a uh, rather vintage and uh, crusty looking main unit, the main CRT and the uh, neck board on there high voltage Supply We've got our hard drive in there.

there's a Sony power supply we uh, try and access the uh. all of that in more detail but yeah, there's all the crud and I really should take this thing outside and just blow everything out of it and on the high voltage CRT Driver board on the side here it takes up the whole side of the Uh cabinet here, the whole uh, left hand side looking from the front and uh, it's got big uh protection cardboard sheet on the side with various instructions with the uh adjustment potholes which is really nice. We got Focus adjustment we got cut off we got width and height so you could get in there and uh, if you didn't like uh, the width and height of your uh, the screen that they gave you out of the factory presumably you could adjust that right to the edge. Warning: this board here is y Yep, there we go.

just a uh shielding uh sheet there. rev E jeez how many revs did they? They went through a few revs just for a shielding sheet with a plastic insert of course plastic cover on that and Tada we're into the back of the board. Look at that. Beautiful! So what we've probably got here is a Uh four layer Bo Board Of course you can see the uh, internal uh planes in there.

it would have it would all be running on the same uh 5volt Power bus Of course they probably don't have any uh, other voltage rails in there or not too many. You know they'd have some for uh, you know, cereal and uh, stuff like that of course. but all the logic would be uh 5V logic and uh, look, probably that's our main 68,000 processor and another Uh custom chip in here that looks like it's probably our power connector up there. and uh yeah, just a four layer board.

It's neatly laid out I like it and you'll notice that down in here they've actually got uh something which was, uh, quite Innovative on a Apple Macintosh was an expansion bus connector down here and uh, even to this day you can buy like a add-on uh, expansion cards which uh, you know, speed the thing up and uh, have much faster processing and co-processors and all sorts of stuff and uh, you know it was sort of. You know you could plug the card down into here, but of course apparently it was uh, it's right next to the high voltage part of the CRT here and well, you know. um yeah, it's not good. that's why Apple recommended that users do not, uh, replace or you know, plug in those boards themselves you to take it back to a dealer or that was their recommendation.

Anyway, now trying to get my hand in there to get onto the Uh lever to pull out to Uh to release the power supply connector in there. You see how they put that oval cut out down the bottom, down there you? so you got to stick your finger up under there like that to try and oh man, it's next to Impossible I Don't know how the workers must have had small hands. it must have been part of the requirement. There we go.

a no, oh man, this is a pain in the ass. Well I got it. So uh, if this uh, full-time blogging gig goes to buggery, I could probably get a job in the Apple Factory Brilliant Now I think the board looks like it probably just slides out. Yep.

I think I've got all the cables. oops no oops. There was a looks like a two pin speaker connector which I uh probably bent the pins on that. but Tada There we go.

Beautiful! And here it is. Here's the main board in an Apple Macintosh SE Brilliant. and uh, we look at uh, several of the chips in more detail and now we have the Apple logo on there and this is the dip. Sim Mac SE model.

It's got 820 -250 19 Copyright 1988 and it's got a barcode label on there as well. If anyone knows how to, uh, you know, decipher that barcode label. Uh, where it came from and uh, you know um I don't know what Factory it came from Is it a you know, a revised model or whatever. Uh, let us no.

And here we have the main Motorola MC 68,000 P processor. It's upside down, all the electrons are going to fall out. There it is. and next to the main processor.

here we have looks like a custom Apple Asic chip. it's the 334 S603 and date code 8836. so um, and 8826 on the processor here. Uh, and most of the other chips are 88.

you know, sort of mid to late 88 uh week branded. So it looks like this thing was was probably manufactured at late 88, early 89. It's got copyright 88 all over the thing, so it looks like we do have a vintage 80s model here. Love it.

But uh, this custom um Asic um I only had a brief uh look for it and apparently it uh, integrates Uh 19 uh chips from the plus a gal chip or something from the original Mac plus and apparently it accesses the memory which is above it uh, twice as uh, fast as it did in the Mac uh plus so you know, faster updating and that sort of stuff. So that really uh enables a lot of the functionality in this Mac SE And this board has all four Sim slots populated and I believe there are 1 Meg per Uh slot. so this has the full Uh four Meg um in it Beauty and you can see the Uh expansion slot over here, heavily tied into the processor by way of the tracers. there is.

There's some LS Uh 45s there as well, presumably to uh help with that. and um, the reason it's called the Mac SE is because it's apparently stands for Uh System expansion because it had this expansion header in it and we have some 74f Uh series logic. Fast logic 257 to Uh presumably uh looks like it hooks into the memory there and up in the corner. Here we've got two tactile switches marked A and B I.

Have no idea what they do I have to look it up I hope I didn't It is battery power by the way, there is a battery backup uh battery in here so well yeah, I don't know. They don't seem to protrude from the case to the outside world anywhere, so no idea. Am26 Ls30 and Companion 2 Companion Ls32. There are Rs 432 drivers and receivers for the serial bus and then we've got an MC Uh 348 that's an RS 42 23 Uh transceiver.

And here we have the classic Zylo serial Communications chip and the two Apple ROMs. They've actually got those uh masked um for them. so they're M ROMs Copyright Apple 1986 and by the way, um uh NYC resistor the uh hacker space Uh, they actually found some hidden images inside the ROMs images of the developers. There were several photos of Uh groups of the developers of the Macintosh hidden in there.

So I'll link that um down down below. so check that out. It's really interesting how they reverse engineered these uh ROMs and actually got the images out of them. It's beautiful and there's the main Crystal there 15.66% We have a classic 16 L8 pal that would just have some glue logic uh in that and it looks like a um, some sort of V LSI um Asic custom Apple chip as well.

that's um, copyright Apple 82 Ancient and there's another Apple branded part and that's the realtime clock chip. it's you know, probably just an off-the-shelf clock chip, but they've uh, got them to custom brand at Apple for them. So that's happened a lot in this thing. So Apple seemed even back in uh, you know, the late 80s.

They seemed quite paranoid about getting Apple branding on a lot of these chips. And there's an Apple branded uh chip manufactured by Sony 343 45b and it's got snd above it. So I'm presuming that is the sound chip and it makes uh, sense because it's not uh, too far away from the sound uh output port on the side there and check this out folks. Look what we have here.

we have a microchip part as in microchip pick this would I'm fairly certain would be an early uh microchip pick part and of course it manufactured by Microchip. it would be masked uh romed as well and that is for the ADB You can see that written on the right hand side. that's the Apple desktop bus. So they're using a microchip pick chip in an Apple Macintosh SE go figure And down here we have a Uh Classic Rockwell Uh branded 6523 VI or versatile interface adapter that's got various timers in it and parallel interface and uh, some serial stuff as well.

Very common chip in PCS back in the80s and down the bottom of the board near the scuzzy connector is obviously the Scuzzy uh controller. That's the Am 5380 which is capable of a whoop in 1.5 megabits per second. Woohoo! Hold on to your hat. And just for my German viewers, made in West Germany V Brilliant and really, uh, that's all there is.

Uh to the main board, there's uh, surprisingly, uh, not much on there at all. It's very well integrated with uh, you know several Uh, As6 and stuff like that so you know it really gets the Uh chip countdown. And there's the 3 and 1/2 in uh, hard drive folks. Much bigger than today's Look at that.

a mix of through hole technology and also uh, you know, like surface mount Plcc stuff. you know, even a dip ROM on the thing. Can you believe it? Little hybrid over here. Check that out.

Little uh Sip. Yeah, it's a Sip hybrid single inline package. uh ceramic hybrid that's been gunked down in there. It's uh, thoughtfully got a date code on there 30th of SE September 1988 So this is definitely an 88 Vintage machine and this is a who in 20 megabytes.

Um, not sure sure who the manufacturer is though. And the power supply here is this: Sony model CR 44 and uh, there it is. It's got the specs there: 5 Vols at 6 amp plus 12 volt for the sweep at 1.25 amps and uh, plus 12 Vols for the disc at 2 Amp 2.1 amps and- 12 Vol at half an amp. So I think I might call it quits for the uh, tear down part of this thing today I won't get into I won't take out the drives and the power supply and all that sort of stuff.

Sorry for you power supply afficionados there, but um, yeah, I want to, uh, actually put this thing back together? power it up and uh, I've only got a little bit of time left to do that, so fingers crossed, it actually works all right. Let's try and power this sucker up and see if it still works. Let's give it a go. There's a switch right on the back here, which is really annoying.

Don't know why they designed it. Oh beep, nice clunky noises. Listen, got a screen. It's flickering.

It's flickering more on the camera than is in real life. It's going to do anything. Hey, we have a mouse pointer. Hey welcome to McIntosh Byebye we're in.

Looks like this thing is working a treat. Sorry, you're getting a flicker on the Uh display on the camera display here. Not a huge amount I can do about that I don't think and we have a mouse pointer Mouse is working. Woohoo! we're in hard drive trash can Apple icon Tada About the finder we're in Finder 6.1.8 and the system uh ROM is 6.08 Larry John Steve and Bruce good on you Apple computer Inc Uh, 90 uh 83 to 1990.

It's got a total of 4 Meg memory and the finder takes 160k and the system takes 790k. Jezz! If you had a standard 1 MGA system, you wouldn't have much left over at all if you had the finder and the system in there. Lucky this one's got four! Meg And Woohoo! we have a screen saver that's turned on! Oh look at that state-of-the-art Graphics there folks and sorry folks I Can't get rid of the Uh flicker on this thing and the white balance may actually be slightly out because it on the LCD here it looks a bit blue ish. um but it's actually a black and white display of course.

Now I can actually go in and uh, change the white balance so let me try and adjust that. So there you go I Turned it up to uh 5,000k in the lab Here it's normally a normally shoot at 4200k and that's what it. Uh, if you do the white balance adjustment with a white sheet of paper, that's what you get but had to uh, turn it up a bit to make it. uh look I think uh, more realistic on screen to what it actually is.

So we got black and white. So here's the Macintosh And of course we only have a single Mouse button. Check it out! Now there's two mouse button business which is a bit, um, hard for a uh a Windows person like me to get uh used to. So let's have a look at the calculator here.

Stunning, state-of-the-art Four Banger calculator as they're called. Terrific stuff I Love it Key Cats Microsoft Mail Scrp Book Staff Directory: What staff directory probably still has someone's data on it I'm assuming I don't know if that's uh, normally part of the Uh I assume it's not. So I assume it's like some sort of app that they've installed. It's taking us fat time about it, that's for sure.

Staff Directory: There you go. all well, no, clearly no, it's an app they've installed and they haven't uh got anyone in there? Whoopy Do! Let's get out of that and let's have a Key Cat Microsoft Mail Control Panel Chooser Alarm clock Let's go into control panel. You can hear the hard drive clunking away in there. It's great.

Ah, there's the Uh screen saver. there you go and file saver keyboard. Oh, can't do two things at once Mac TCP The mouse. So even back then they had uh, you know, networking, local talk and no, there's not anything terribly interesting there.

So let's go into um special restart shut down erase disc don't want to do that set startup option so that's pretty much or you can do in there. and we don't have any other programs installed on the Apple menu there. So let's go into the hard drive and hey, there's program Sim City Looks like it's got Sim City installed and virus tools and system folder and that's it. Let's go into Sim City Let's play it.

Look at this Dave town I Love it! I've got to have a look at Dve Town So assuming we can double click on that because it is associated with the Sim City app, there we go. Sim City Circuit Simulator Version 1.4 Copyright 89 to 92 Brilliant! The Sim City still around are people still play The Sims Oh, look at that city map comp. Comprehensive. Shut that down.

We're looking at dve town I don't know how to play Sim City Looks like we have $51,000 in funds. It's I Guess the date is February 2028. Is that right Bulldozer area for a dollar? Oh we had some uh oh, look at this. no no color cuz you you can't figure out what's what here.

Uh I have no idea how to play Sim City Oh look I'm bulldozing everything am I Is that what I'm doing? Oh terrific. Good stuff. What options have we got up here? File options Auto Bulldozer Auto Auto Go to game Speed Disasters fire, flood, Air Crash Torado Earthquake Monster Love A Monster Let's put a monster in now. Can we put a monster in there? No.

I don't know I don't know how to play this stupid thing. Oh Oh Monster Attack: A large reptilian creature has been spotted in the water. seems to be attracted to areas of high population. There is a trail of Destruction wherever it goes.

As a last resort, try calling blah blah blah blah blah sorry I don't know my uh kangi characters there. Other than that, wait till he leaves and rebuild from the rubble. Oh dear oh man, everything's quite slow. like the redrawer on the screen and stuff like that really is bottlenecked.

Load Scenario: Save changes, No oh, look at this. San Francisco 1906 Earthquake Hamburg 1944 after the bombing wasn't much left of Hamburg I've been to Hamburg great City Love it Detroit 1972 Crime Monster Attack in Tokyo A Boston 2010 Meltdown A major meltdown is about to occur at one of the new downtown nuclear reactors. Woohoo! Fantastic Look at that. There you go Anyway, this sucker seems to work a treat.

I Like it. It's go into programs here and see what we've got. Oh, you can't No, you've got to actually click on the little folder there. Microsoft Works FileMaker Uh, MC Stats View Tools Microsoft Exel Let's try Excel Love the sound of the hard drive going clunk clunk clunk clunk.

Oh, the application Microsoft XL has unexpectedly quit too. What a bummer. Ah, fail. Tools.

Copy two. that's for copying this I think and uh, super convert a life belt. eh? boring. So there you go anyway.

It seems to work. An absolute treat. Very very old school. I Mean it's very slow.

You can see it drawing the windows and stuff like that. You can see it actually drawing the menus up there. and it's just incredibly slow. All this, uh, graphic.

cuz back then you know this was very graphic, uh, intensive stuff. So it you know it really. uh, struggled to do the business back then with the processor uh, and the speed that these systems had. And if we select our hard drive here and have a look at the info, what do we got there? we go.

Uh, 12 and 1/2 Meg used and just over 12? Meg uh available I guess on disk? There you go. So that's a, you know, a 24 25 megabyte dising this thing. uh, scuzzy of course. And there's 155 totals files total on the disc.

I'm going to presume that that, um, uh, you know, includes all the system files and everything else nowadays. 155 files? Gez one of my tear down videos, you know I generate 155 files crazy. Well, I'm afraid is uh, interesting as this thing is. from a retro point of view, it's absolutely useless for any but I Just love the uh look and the form factor of this thing.

So if you got any ideas of what I can actually do with this uh classic Apple Macintosh SE uh please let me know in the comments or on the Uh E blog. Forum so I don't know you can take the screen out, turn into a fish tank or something like that. but Heck if you got any good ideas let me know. catch you next time.

Um.
