I have Spectrum 24/28 in my A3000. Originally I installed no hassles with the original GVP installation floppies. I see people recommending Picasso. That's fine. I went the Cybergraphx 4 route and it was flawless for the Spectrum 24/28 card. That is how the machine runs to this day. In my opinion, this video card is not all that bad. For an original Amiga to display what this card can display, is very cool. Keep trying with this card. It will be worth it when you get it running. I was so happy to leave the ECS world of hell with this card. I have run it successfully with Workbench 3.1 and also OS3.9. The A3000 machine currently runs 3.9 but I will trash this and go to an optimized Workbench 3.1 system soon, with the GVP video card of course.
