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...
