Not quite a ribbon cable... "internal" massbuss cables are a set of 3,

pulled one apart to check). This would connect to a multi-board
massbus controller in the machine.
Oh, and it uses three-phase power (as do all the RP disk drives). The
RP06 isn't too bad, power wise, it only is rated to use 12A at 208V 3

We're running our 2065 at the PDP Planet site
off an RP06. An
interesting experience, to say the least. -- Ian
Please continue.
I wish I'd paid more attention when the DEC service guy was doing PM.
I assume it's massbus, which means (i'm out of my depth here) there
is a ribbon cable from the drive to a controller which in turn
connects to the backplane?
