Today was the monthly electronics flea market at De Anza College in Cupertino: http://www.electronicsfleamarket.com/ There's often a bit of old Apple stuff there, but today was exceptional. There were several different vendors with ImageWriters, LaserWriters, keyboards, disk drives, power supplies, and of course Macs. We saw lots of old iMacs, a 20th Anniversary Edition Mac, a Performa 6000-something, Powerbooks, and more. I bought an Imagewriter II for 75 cents, but my friend and I managed to resist the temptations of the other Apple hardware. At least we did, until...
One of the last vendors we visited had PILES of vintage Mac stuff. He probably had 20 assorted Plus and SE systems, along with a IIci, IIcx, IIx, LC, a Duo, and more that I lost track of. Tons of this stuff! He also had lots of keyboards, a box of about 100 double-density floppies, spare analog boards, random accessory cards, and spare logic boards. He didn't seem too familiar with what he was selling, so I think he must have bought the whole Mac lot from another collector.
In the pile of logic boards, my friend and I found a few gems (or what we hope are gems). We bought three logic boards for $50 total.
The first is an extremely clean and beautiful looking specimen. I'm not 100% certain, but I think it's an original Mac 128K board. The logo on the RAM is one I haven't seen before, though, so it may have been upgraded to 512K RAM at some point. What do you guys think? When powered up, it chimes but then displays a Sad Mac with code 020800. Here's a photo of the board, and close-up of the RAM:
The second board is a little bit grimier, but still pretty good. I thought it was a Mac 512K logic board, but it seems to be a 512Ke, because it was able to boot from my HD20. Maybe somebody swapped in the newer ROMs at some point? The board has two boxes for checking off 128K or 512K, which I thought meant it was a Mac 512K and not 512Ke. Anyway, it works fine. Photo:
The third board is the one my friend grabbed. I think it's a Mac 128K logic board, but probably one that's been upgraded to 512K RAM. It has a tiny daughterboard next to the CPU. Has anyone seen something like that before, and have a guess what it is? He hasn't booted it up yet. Here's a photo:
