Re: Arcade Renovations 'new' monitor

Actually Zonn,

    I wanted to us a pic for the processor and with maybe a very simple DA
converter. If you have a proto or example then that would be cool + you'd
have the cource code then too. ;) Right now I waiting back for a call from
wintron... Wish us luck...
