Guess I opened my big mouth didn't I..........
I went and took a count of what I actually have. Turns out, there wasn't
quite as much as I thought there was. I was unable to locate any prom boards or
prom programmers :-( , but I did find three of the expander boards. I can send
these out in the mail, which souldn't tax my resources too much. Bigger problem
is probably going to be finding the manual, but I think I know where that is.
So, Old Crow gets one (send me your address). Anybody else interested?
