1) Does anyone have a spare set of control and data
cables? I'm willing to
pay for 'em, or visit Maplin for components to make up a set, since they're
probably easy to make with IDC connectors and ribbon cable.
If you want to make them, then it is very easy. They are just
straight-throught 20 (data) and 34 (control) cables. IDC header sockets
on one end, edge connectors on the other. I am not sure if Maplin still
do the necessary bits, but RS/Farnell do (and IIRC the latter sell IDC
ribbon cable in short-ish lengths).
The original IBM PC/AT control cable had a twist in some of the wires so
that boht drives cound be wst to the same DS line. But unlike the floppy
cable, whenre the twise is needed to geve separate motor control for the
2 floppy drives, the twist in the hard disk cabel is not necessary. You
cna use an untwisted cable and just set the DC links appropriately.
