Attention!!!! Pleas delete Gerber file with date 24.09.2020, it has wrong marking "F126" on U31, F125 is correct. If your PCB is already produced: don't be worry, ignore "F126" Marking and place it on U31 with 74F125. Gerber file in last post is already replaced. Sorry!! matt

Thanks ! PIcture resolution is more than good for researching of SAUP decoder. But now i have a bad feeling: Trio64 compatible mode. I found only one SAUP decoder (74F260, 2x 5-input NOR ) Pleas wait, i'll decoding config resistor strap. Then i can make: Virge VL based STB card or new (minimal) …

Trio64 card can't convert to ViRGe, to much difference on pinout. Only Trio64V+ in Trio64-compatible-mode can this. You're right, STB PowerGraph 64 Video is a Trio64V+ Video card. I hope, i found good pictures of him for researching of SAUP-decoder-ciruit. I hope, it runs not in trio64-compatible- …

Interesting topic. I also thought about modding a Trio64/VLB card into a Virge/VLB card, which would be cool. I confused some things in the first run, but I got some of the stuff straight now: The Trio64 features "glueless VLB support". Glueless means that you can directly connect all relevant VLB …

Thanks for flower :-) Yes, it is typo, Mercury P64V , not Mirage. (Topic is already corrected, thanks) ROM of Mirage P64V would run only in text/VGA-mode. (I haven't checked, lol ) ROM came from Mercury P64V , which it exists never as VLB-card. But ROM is direct useable for VLB card. It doesn't make …

Short explanation: VRAM Card from …
