I have to remake an EL02 cable (Or at least the board > bulkhead part)
for this to work. (This being the RL02)
Is it a straight through cable?

[RL02 cable]
I have a straight-through cable I snagged from a DZ11, I'm trying to use it. I can
get the FAULT light to go out, but I can't spin the drive up.
When I have it connected, I get no lights on power on, WRITE PROT will switch
on and off when pressed, LOAD doesn't, and putting a pack in doesn't help.
Is the drive dead?

Stupid question:
You are putting the bottom cover of the disk pack
on top of the disk pack before you close the top,
aren't you? The "lid closed" microswitch won't trip otherwise.
Tim.
Here is an even stupider question. Bare with me, I've not seen a RL02 pack
yet, but I've used simular drives on Honeywell and UNISYS mainframes. The
bottom cover sort of clips onto the bottom, right? You take it off, screw
the pack into the drive and twist off the top cover? So you're saying you
then put the bottom cover on top the disk pack and close the lid?!?! I'm
hoping the bottom part of the cover is now sticking up!
Am I understanding this correctly?
Somehow I'm glad I saw this prior to finding any diskpacks for my /44! I
don't think I would have ever figured that one out :^/ Don't mind me, this
just sounds SO wierd, compared to the drives I'm used to.

Uhh, no, the directions didn't mention that...
I'm supposed to put the bottom cover of the pack on top of the pack, then close the
lid on it?

Here's one - when I put my - probe of my voltmeter to the -15UNREG
and the + on +15UNREG, I get 28VDC. Not good?

Here goes...
1. Put it back together. OK, gimme a sec...
2. Cable drive to controller. Substiuting DZ11 cable for RL02 cable.
3. Power to drive... OK, fault for no sync... and CPU, OK.
4. close lid... OK
4. LOAD switch: Lamp's burned out... WAIT!
Interesting! When I leaned on the cover for a sec, it started spinning!
Maybe if I go sit on the drive... Ehehe THAT WORKED!
Apparently the interlock is shot, 'cause the drive won't spin unless
I'm sitting on it! I've gotten the crews as far as they go...
I'll go sww what's buggering up. At least I know what! Oh,and the heads
load, 'cause READY comes ON. Thanks!

[Sit on switch]
That solution got old real quick :) Lid is too hard.
(And I'm afraid I'll break it)
Fix ended up being sticking a screwdriver in the side of the lid, by the switch
The cover wasn't pushing down hard enough to trip the switch. Now, I've booted
RT-11 from that one pack (Worked just fine!), Copied it to DU0:, and tonigh
I'm gonna kermit over the V7 Unix pack image and write it to the pack.
Any special trick to doing that? I remember a long discussion about doing something with
the bad-block table at the end of the disk...

[Servo failed?]
It must have - I have NO movement. If I remove the cable from the logic
to the AC servo stuff (By the motor) and reinsert it REAL slowly, thr drive spins up
untill the cable is fully inserted, at which point it fails.
and spins down. As soon as I remove the cable the fault light comes
on, so no using this to spin it up...
No movement, no buzzing.
