Oops-- You're right, of course. Can't wait to get 'em spinning... Can the
OpenVMS page file (or whatever it's called) span disks?

The vertical board to the left of the power supply is for a SCSI array.
Seems the chassis could be loaded with RF or RZ drives, choose yer poison.
Alas, I don't have a qbus SCSI controller, nor a quantity of 5.25" FH SCSI
drives to fill it with. Taking donations to fill both needs... :)
Seriously, I could use a couple of FH SCSI drives for my 4D/35.

I *think* I might be able to get away with two of those SCSI cables that
brings out a (HD honda-type SCSI2) connector to an ISA card backplate joined
into one, since I need two female connectors. IIRC the DSSI connector
carries out ground on every other pin, and I could make do with <18" if I
put the two boxen back to back.
