Heh. Congrats :-)
What OS are you going to end up driving this from? (It is on a PCI card isn't
it, rather than a USB interface?)
Regarding earlier question about bringing some address lines out to the I/O
connector... the logical choices I suppose are a 40 pin header or a 50 pin
header.
40 doesn't seem like enough though assuming you keep odd pins as ground still;
it's only another 3 pins, and won't you need one of those for the write
precomp line for 8" drives?
50 would give you an extra 8 pins to play with[1] though. If one of those is
reserved for a write precomp line, that still leaves seven unused. Say reserve
four for addressing, and the other three for the uses which we haven't thought
of yet? ;-)
[1] Assuming the ability to have two drives on the same cable as per the PC
standard... if you don't do that I suppose it frees up a couple of pins of the
'standard' connector.
