If you use that conenctor, you need a 40 pin BERG-to-BERG cable (whcih
you can trivially make) to link it to the controller. AfAIK it'll work
with an RL controller, nop matter what DEC normally supplied.
Seems silly but it might be easier to scavenge
the connector off the back
of a dead RL01 or RL02 and make it into the transition than to find the
actual transition!
It's the same part, AFAIK. What I have on one rack is a special DEC
mounting bracket that can accept two of the round-cable-to-flat-cable
transitions - it's a bit larger than a pack of playing cards and
easily affixes to an H960. Mine has one transition connector, but
there is room to mount a second one. Having worked on a few RL01/RL02
drives, ISTR it's the same part that's bolted to the back of the
drives. All drives: round cable with ZIF on each end to go
from drive to
drive, plus ZIF-connector terminator that is externally identical to,
but not electrically identical to RK06/RK07 terminator.
The cables are differnet betwene the RLs and the RK06/07 (the latter has
all pins bet one (termintor power) connected, the former has rather fewer
wired), but AFAIK the terminator is the same (it terminates all signal
pins. I think at least one RL controller printset shows the exploded view
of the terminators with 'First used on Option/Model : RK06' specified.
