Whoa, good cross section, and missed the ST351A/X? This is one
of rare drives that can be jumpered for either physical 16bit or 8bit
mode.
Allison seems
to be the only one who's tried this, and, I fear, it may be

a PC-compatible, where all bets are off as to what
really happens.
Obviously visually impaired! I don't hack IO in PCs nor have I tried that
yet.
I may add why even bother, IDE works there as is.
ALL of the IDE work I've done was with 8085, z80s either stand alone
(bus less) or S100 Z80s. Further I'm currently working on a Z280 system
with IDE (Zbus 16bit). This is where I need interfaces and so I can replace
older MFM or non-existent hard disks. I currently have one S100 system
running a connor3044A (40mb) IDE that will be upgraded to a ST3250
(250mb) as it's a better drive.
The drives I've tried include:
I do have two WD PS/2m30 compatable 8bit IDE 20meg drives.
I think this is a good cross section
