Good you are still here and best wishes.
Does that mean you've been able to reverse engineer the SuperGoldCard's EPM1810 and move the logic into a EPM7128?
Congratulations then! Sorry if you wrote about that previously and I missed it.

Yes, recently I was able to solve the INGOT20/21 problem.
Amazing. To reverse engineer the SGC logic without sourcecode is a fantastic achievement. Congratulations and applause to you!
That would be great. By the way, are you already selling those boards or are they still under development?
I had the original INGOT file ( A-PLUS ) from Derek, but with a lot of errors that I had to fix while parsing the INGOT firmware file in manual mode.Peter wrote: ↑Sun Apr 02, 2023 6:46 pmAmazing.

It is also a very beautiful board. I like that you are using through-hole components whereever possible.
Keeps the spirit of the time when the original was designed. Reminds me of Q40/Q60 where I did the same.That would be great. By the way, are you already selling those boards or are they still under development?
That is good.
Sounds like a good idea.
Since you are on a writable data bus, the QL-SD magic for writing by reading (with data in the lower 8 adress bits) could be removed, gaining some speed. But write speed is much less important than read speed, so the overall gain may not be worth the effort.
Very happy to hear that you are fine and back with us !tetroid wrote: ↑Sat Apr 01, 2023 11:17 amDerek_Stewart wrote: ↑Sat Apr 01, 2023 9:05 am Hi,
Maybe an existing disk interfaces could be reverse engineered, what would be the interface required, bearing in mid the Super/Gold Card suffer from custom chips that maybe unavailable.
