RE: Sega Vector Development Tools Project

Since we're on the topic of G80 systems...

1> First, it's been a while...too busy for my own good. Can the G80 system
run without the audio and speech cards installed? I recall Tac Scan didn't
have speech.

2> I totally forget this as well....does Clay's multigame kit virtually
replace the CPU board? Suppose I had a means of driving just the control
and timing board with the multigame....what other logic would I need. From
the schematics, I see only a few control signals...does anyone know offhand?

Thanks!

Sounds like a great idea! Keep the updates coming.

Does ANYONE on this list have the G08ed program that Clay Cowgill came
up with long ago? Would be a nice base to work from (as Mark noted).
