Awhile back I was looking for a caddy for my RRD40, but the ones I
found and received (thanks Joe) weren't for the RRD40 but for RRD42.
RRD40 takes a weird plastic-only caddy that looks like a pair of
pincers, precariously pinching a CD at the edges...(anybody who'd like
a pic can email me offlist).
Anyway, my RRD40 I discovered unfortunately was nonfunctional *sigh* :-{
The caddy with VMS7.1 was jammed inside and I had to strip the drive
down to the internal unit to extricate the caddy and CD. There doesn't
seem to be an EJECT button for the RRD40????
So after I've extricated the caddy/CD by raising the motor/spindle
clamp manual, I discovered I cannot insert/load the caddy/CD with
raising the spindle clamp. Of course I could only do that with a
topless unit...
I could only conclude that the load/eject mechanism is kaput....
Any clues anybody? Or time to look for another RRD40....
/wai-sun
p.s. I had hopes for the RRD40 to be a boot device for my u/VAXen...

Well the caddy is supposed to be a beige plastic "antlers" AND a
transparent plastic "case". If you only have one part, maybe that's
your problem.
IIRC to insert the disc (which is held by the "antlers" inside
the "case" you push the "case" into the drive "antlers"
first.
Then you withdraw the "case" and the "antlers" + CD stay inside.
The "antlers" have DATA written on one side - the CD data (non-label)
side has to be on this side. The case is inserted with the CD label
side uppermost.
As the Haynes manual would say, "Extraction is the reverse of the
above"
There are two LEDs on the front. The lower one indicates power present,
the other indicates a CD inserted.

I suspect it WAS perfectly functional. Whether it is functional
now is another matter :-)

No eject button needed!

From your description, you are obviously missing a
case.
p.s. I had hopes for the RRD40 to be a boot device for
my u/VAXen...
If you have nothing faster (TU56, paper-tape etc. :-)) then it will
happily work as a boot device for MicroVAX 3100 systems. It would
probably work for MicroVAX I/II systems as well, if you have an
appropriate interface card (either Qbus SCSI or a KRQ50).

Err...you would have a case handy would you? :-}
Yeah I have the KRQ50...
Do you have the pinouts of the LMS interface connectors (10pin and
16pin) behind the CD?

Yeah I'm caseless..... :-(

Hmm...the antlers/CD were jammed inside with the antlers facing the
frontpanel/user...

Yup I saw that.

Power LED is fine.
I can get the CD present LED to light up but manually inserting the CD
in, so sensors should be OK.
