Hi all,
I got a UNIBUS ESDI controller and I'm currently shopping for a disk drive
for it. What I was thinking of doing is mounting a bracket inside the
BA11-K and powering the disk drive from the BA11-K power supply, just using
a molex connector to one of the unused harness connectors on the power
distribution board that supplies the correct voltages.
Would doing this pose any sort of problem? i.e. violating amperage limits
etc? It would probably be something like a Maxtor XT-4170.
I can't believe it will take too much current for the BA11-K regulators,
but one problem you'll run into is that most (if not all) hard drives
need a +12V line, and that is not supplied by the BA11K. There is a +15V
line which you might be able to regulate down, but that one is not rated
for much current (4A?). Probably enough, though.
