I went over to my storage today, and thought I'd found the box it was
in since it had another 990 manual on top, but it turns out it was
otherwise a box of TI-99 stuff. ROM, GROM, DSR sources, product
manuals, specifications, etc. Interesting but not what you're looking
for. I'll take another crack at it later today if I get this guy's
overheating van fixed before dark.
