A fleet of Macintoshes

Today I visited the Apple Museum of the Netherlands, in Orvelte. Although I loved the tour of the museum given to me by the owner Klaas, a real cool dude who knows his Apple stuff very well, I was invited because I had put up an ad looking for broken Macintoshes to repair. My idea is to buy up dead Macintoshes, and fix them up. The ones I do not yet have I keep, and the doubles, I sell for a little bit of profit (I'm not looking to make a fortune off of this, so my prices will be below market value so other enthusiasts can have some fun too), and Klaas responded to me that they had some broken ones left over, and I could come over to negotiate acquiring them. After having a great tour, and learning some things I did not know, we went upstairs to the staff/repair area.

And there they were, a pile of 6 different Macintoshes. 2 Plusses, a Plus ED, an SE, a Classic II, and its brother, a Performa 200. For those who don't know, the Performa 200 is just a rebadged Classic II. We agreed on €100 for the bundle, a really nice price I'm very grateful of (Thanks Klaas!). I was told that one of the Plusses did work, but had mismatched parts, as the main plastic body was much more yellowed than the front piece. The ED had a note that said the analog board was having issues on that one. I did not get any keyboards or mice with it, so I do need to get a RJ11 Apple keyboard, DB-9 Apple mouse, and a ADB mouse (I already have an SE with ADB keyboard). 

At home, I tested them. As said, the one Plus works as was told. The other one too, but it has a big hole in the back, along with two small holes next to it, indicating there was some sort of DIN connectors at some point there.

The ED has a loud whine when it is on (probably bad caps/flyback on the analog board, as the note suggests). The SE had a sticker on it that says it needs a new HDD, I noticed at home, which is indeed its only apparent issue, other than probably needing a good disk drive lubrication.

The Classic II, of course, was showing black and white bars due to leaky caps. I attempted the temporary board washing solution on it, leaving it for around 45-60 minutes in warm soapy water, then drying it above a radiator on full blast until not a single drop of water came off when I waved the board around, and sure enough, it boots up fine once again, although complaining about not having enough memory for extensions. So that'll be a fairly straight forward recap job, although I do need a SCSI cable and some screws for it, as it was missing (some of) those. And also some RAM as that was also gone, probably used for different working Macs, which is why it whines about that upon booting. Performa 200 is playing dead, CRT does not come on despite fan and HDD noise being heard. That's gonna be a bit trickier, I think. 

Anyway, I'm gonna have some fun fixing these up, I'll probably try to retrobrite the Plus with the mismatched plastics to make it uniform again. I'll see how long it lasts on that before trying it on the others. Gotta have to wait for some sunnier days, though.

Update on the Performa 200, I got it to boot to a garbage screen once, after that it kept not displaying anything at all. I decided to repeat the washing process, and sure enough, it now too boots up, although it is giving me the error code 0000000F 00007FFF. The sounds are also extremely quiet, but this could be due to the bad caps. Either way, that's another recap job at least. Anyone got an idea what that error code entails?

What do you mean by 'it boots up'? Does it boot up to the flashing question mark? Or does it crash before that?

Could be a number of things... Could be RAM, could be the OS...

Did you try powering it on without an HD? If it works, then it's probably* NOT RAM related.  *a Mac may pass the RAM test with some corrupted RAM... The test ain't perfect.

How much memory does it have? You should remove the two SIMMs from their sockets (if present)

The Classic II has 2mb of RAM onboard. So something could be corrupted on those chips as well... Did you give the LB a nice good scrub near those chips? (just above the sockets)

Unfortunately there is no list of the Sad Mac error codes for the Classic or the Classic II...

It shortly boots to the Happy Mac to then fail, regardless of whether SIMMs were installed or not. But I already chalked it down to a bad OS install or HDD, as swapping logic boards did not fix the issue, ruling it out. The SIMMs work fine in the other machine. Of course a screw for the drive caddy has decided it doesn't want to come out, so I'll need to find a screwdriver with a better grip, and carefully get it out without stripping it.

That's a relief. I've had weird boot crashes on an SE/30 before that were due to a bad solder joint on one of the capacitors.

Brilliant! Keep up the good work :) I'm spending tomorrow recapping - these little computers all need preserving

I now just noticed something a bit funny, and probably the reason it wasn't put on display: The ED is a bit of a Frankenstein Mac. At first, I thought it was a Plus ED because it said "Macintosh ED" on the front, and "Macintosh Plus" on the back (yes, I am a bit of a newbie to these Macs). But, if it were a Plus ED, it should have said that on the front... So it's not an ED nor a Plus ED, it's an Plus with an ED front. Does that count as an ED Plus? :p

Oh well, I'll probably keep it, as it's such an oddity.

Surely it's a 512k ED (they were labeled Macintosh ED when they turned platinum) that got upgraded to a Plus at some point. 

That's a shame because those platinum 512k buckets are INSANELY rare. (well, not that much, I'm a bit exaggerating, but still)

128k->512k->early 512ke->early Plus = beige

late 512ke->late Plus->onwards = Platinum (greyish)

Here are a couple of pictures of said 512ke Platinum:

It gets confusing because both platinum and beige Macs yellow over time...
