http://digitpress.com/forum/showthread.php?t=153253 Not sure where to stick this honestly. Over on DP here someone is selling hard copy printouts of the Vectrex's BIOS source code. Asking price is a bit high for my tastes but this might be of interest to someone. He did scan a few pages and put them up online.
What is it with gaming forums going members only of late? Eh, it's the Vectrex. I really couldn't care enough to pay anything. If you're saying it's a bit steep, then it must be - having to pay in the first place is too much for me! ;-)
