I have the schematic of the cable and adapter board somewhere but I won't
have time to look for them anytime soon. The adapter board has some tricky
wiring on it and IIRC the cable IS NOT straight through. I've had a hell
of a time getting non-Intel disk drives to work in the MDSs. I have quite a
few of the same model drives (with different revision boards) and I haven't
gotten ANY of them to work in a MDS. Yes, I've set all the jumpers. I've
spent at least three days trying various drives but never could get one to
work. My suggestion is to search out an Intel drive in the surplus places.
Intel sold a LOT of these systems and there used to be a lot of them in the
surplus equipment places.

Hi Joe
When I worked at Intel, ( I recall ) I was told that the
M2FM drives had a few capacitors changed in the input amp section
to increase the high frequency response. You might compare
the components from an Intel drive with the same model
drive ( mostly SA800's I thought ). It might be resistors
but it seems like I recall being told it was capacitors.
You could then post this for people that were bringing up
their MDS800's but didn't know where to find drives.
If I get a chance this weekend, I'll look at the drives
I have to see what changes there might be.
