It looks like a fairly standard floppy drive. I might be misremembering or misinterpreted the particulars due to neither me and the hardware guy being able to speak the other's native tongue that well, but the upshot was despite what the circuit told me about the configurability of the controller chip, it was not going to work without DMA.
- kimixa 3y agoThe linked article shows the "standard" pinout for a 3.5" floppy drive, and it's clear the interface is below the level of anything like DMA. I assume even if you were using something that looked like a standard floppy drive, it was using a higher level interface, or was including something like the controller ISA board in the "interface".
