On the bright side that also allows us to implement a pata_mfm/rll driver at last.

I used to have an old drive that was something like that - 5.25"
Seagate 40MB drive. I sold it including the controller a couple of
years ago (it was still working) so no testing fun for me.

Looking at a Western Digital "FileCard 30" consisting of a Seagate ST-125 and WDQC16 8-bit ISA controller. MFM I believe.

I put a sticker on it with: "io=0x320, irq=5, dma=3 615/4/26 (or 614)"

The thing has its own BIOS and if If I'm not mistaken it could only live in an AT+ with all other drives in the BIOS turned of. This might mean I'd be capable of testing it from a boot-floppy only but if you desperately want a tester, I'll try to volunteer ;-)

I remember using DOS "debug" to jump into its BIOS low-level format routine so I did get it doing something...
