Argh, and I bet I won't have too much luck finding an 82929A module anywhere
:(

I'm hoping it would work with the 9122, which is what I want to get for my
1631D. The only reason I'm hunting for 9122 instead of 9121, is I thought
the floppy disks for the 9122 might be easier to find (they DO use different
media right?)

I saw note of that on your website. That would be soooooooo so nice to have
an ROM emulator. Humm there can't be THAT much to the electronics inside the
82929A. Anyone have one they'll let me take apart and build a copy of?
