I could use some (reasonably proiced) spare ][+ mainboards for use in bench testing cards and for other experimental use. No cases or PSUs or KBs needed. The revision does not matter.
If you have any to spare, please LMK. I would like to get one or two known good boards and some spare parts-only boards for spare components to use as-needed.
I would be willing to trade a //e mainboard in the proces, if you need one. I have more spares of these than I need.
I recently blew one of my bench boards working on some custom hardware that shorted something, and I need to order some 74 series chips to be sure that I repair it with good chips. I pulled another very poor shape board from my surplus, but even after cleanup it is non-functional (no video signal) and having spare working boards would savtime for me until I can set aside a week to properly go over these three boards.
I am also interested in assorted spare ICs for them, if you have any surplus. Otherwise I feel that I will need to order five or six of every critical component as NOS parts, which is a tedious process.
I hear you - I just bought a mess of logic chips from futurlec.com to replace depleted stocks on hand.
They have just about every logic chip on the II+ (including 2716s) except the 4116 DRAMs which are getting scarce.
I found a source for 4116s, and i'm tempted to buy it out.
I managed to repair three boards fully, and have one (a rev 04) remaining. It is in very bad shape as it was horribly abused, had wrong chips on it, chips inseted backwards, including the CPU (which I am shocked to say, passed a burnin on a good board!!), a bad/broken xtal, and f'd up hand made jumper blocks missing pins. It has to be the worst ][ board that I have ever seen, short of one that survived a fire, and that one still worked, so perhaps this is genuonely the worst.
