High Speed
Williams, 1986I picked up a project High Speed (Sys11) with some pretty good damage due to what looks like a transistor fire. I've been looking for a replacement Sys11 Board. My question is, exactly which Sys11 revisions will work on this machine? Somewhere I think I read that A and maybe B revisions will work, but you have to stuff the audio components? Has anybody done this? Are these parts available? Advice please. Or, is anyone looking to sell a working Sys11 board? Thank you,
Mike
11 (no letter) will work
11a will work (sans maybe a 4pin connector for sound)
11b will work if you stuff the amplifier circuits in the top left corner. Not hard, i have done it a few times. You will need an amp, heat sink, resistors, caps, etc...
