Great! Thanks very much. It'a a great new! I can surely help to do the tests on floppy drive support. I had a complete system with PEB in '80 and now a TI wih NanoPEB to compare if needed. Moreover, I have compiled the modules list for games/utils that runs on MiSTer, but require a disk drive to be 100% functional.Flandango wrote: ↑Wed May 26, 2021 9:50 pm Sorry to butt in unannounced, but I came across a comment or two about the Ti994/a core not having the drive support that the Mist core does. So I figured what better way to learn some fpga development and get familiarized (somewhat) with Quartus then to try to add the floppy feature to the Ti994/a core.
Now I never owned the system, nor do I have a Mist to compare with but I think I got a core working with two floppy drives.
If anybody is interested in trying out, especially those who know how it's suppose to work, let me know and I can post the .rbf.
Just let me know where to download the core.
Again, many thanks for your work!
