Floppy B Problem
Posted: Sat May 11, 2024 7:17 pm
Using the PCXT it doesn't matter what I select as an .img for Floppy B the emulation behaves as if it's the identical disk as drive A.

I got this to happen in MAME, too. If you have the FDC:0 set to 525dd and you set FDC:1 to [empty slot] it does exactly this.
So maybe there needs to be a way to select the type of floppy drive in the settings to force the B drive into being a separate device and not a clone of A.
Setting the system speed to 7.16 fixed the problem - I was on 4.77 before.
But if you're pushing the drive really hard (i.e. copying the entire disk) it gives up being able to read/write to the floppy after a short time.
Restarting the emulation fixes this in a way...you can go back and copy the remaining files that it refused to copy before.
Ok last post just wanted to say that copying entire disks and reading floppy A & B work well if the speed is set to PC/AT
