I thought this card was working but now I'm not really sure.
It's setup as per the manual for DMA 1, Port 0268 and the drive jumpers are set to AT/COMPAQ.
I can verify that the floppy controller, the cabling and the floppy drive work. When TransCopy 5.4 is run it doesn't complain about not detecting the board either. The problems when you start doing board-level activities.
TC 5.4 will bump the heads but never step beyond track 0 when reading a floppy in. It will however step outwards correctly when writing, but you're going to create an unusable floppy.
TCM 5.4 will read in a floppy and step the heads correctly but then give a CHECK DISK when writing it out, even if the floppy is known good.
Macintosh disk functions all error out immediately. No idea if reading in a disk or formatting is being done correctly as it can't verify so it tries, then fails on the write.
TC 4.7 gives a CHECK DISK as soon as you try and read a floppy in. Again, known good floppy.
PK likewise fails with an 80h error
TC 3.3 immediately stops when you try to read in.
I can boot directly off a DOS floppy and try in case it's something loaded into ram but it's all the same. It's almost like the board is bad? I don't see any configuration options so I don't know if it's just misconfigured or something.
