What is the make and model of the hard disk? I susepct it's actually some
standard drive.
I think its a MFM (ST-506?) style hard drive with a SASI adaptor
board. I'll try to get more information on it.
I have no idea what the Jade probe actually does, but
have you done the
normal tests of checking the supply voltages at the processor oard, then
checking if the CPU clock is running, checking that the reset line isn't
stuck asseted, and then looking for activity on the address and data
lines? Ues a ;scope or logic probe.
The BUS probe is a double height S-100 card that provides a front
panel type display. It has LEDs for the clock lines
specifically. The clock LEDs light up with my 186 card, but not with
the CPU card that came with it.
