I also pulled the CPU board from my 19r and scanned
it. The scan is
not the best - it's a little out of focus and somewhat dim, because the
board didn't sit very close to the scanner glass - but the writing on
all the chips with enough pin count to be CPUs is legible (though on my
monitor I have to stretch the contrast). It's up for ftp from
ftp.rodents.montreal.qc.ca:/mouse/misc/NCD-CPU/board.pgm and board.gif
for your viewing edification. It's 2549x1771; the chips of particular
interest can be found at 700x400 at 1100,200, 400x400 at 800,900, and
400x400 at 1400,875; those pieces, contrast-stretched, can be found in
.../NCD-CPU/X.YYY where X is A, B, or C and YYY is pgm or gif.
The big (?) LSI chip is the CPU. (33000), which was used until the 33020
came out, (RocketX)
