You're idea of an FPGA ST graphics card could be excellent.
I really hope it will be both useful and a fun project.
Steve wrote: 12 Jun 2020 16:05Right now on this forum Exxos is developing a brand new ST motherboard, would be kind of amazing if your fpga graphics option could be provided as an add-on module...
Right on. I put myself down for an H5 and I have those 1040STfs as donor machines. I think I can get my H5 working.
Steve wrote: 12 Jun 2020 16:05There are people who know about driver development, I think Idek is a good person to ask as he writes drivers for the Nova cards, I don't think he's on this forum but he is on atari-forum.com (when it's up) Here is his website: https://silicon-heaven.org/atari/nova/
Thank you for the awesome lead, Steve! I saw this page before but didn't know this is in current development. When atari-forum revives, I'll find him there. I might borrow some ideas from the existing boards to make this easy. I had an ET-4000 manual back in the 90s for some work on XFree86. It's gone, now. Maybe I can find one online.
