Re: Looking for DEC RA80 (or RM80, R80) service manual (EK-ORA80-SV or similar)
My RA81 print set is REV A. I can ship the RM80 pocket guide for scanning, but want it back. I'm shipping some other things to a list member, and will see if he will scan it. It is a copy, about 40 pages.

Re: Looking for DEC RA80 (or RM80, R80) service manual (EK-ORA80-SV or similar)
I have RA60 prints, with notes, RA81 Maint Guide AA-M879B-TC RA80 MG AA-M186B-TC RM80 POCKET SERV GUIDE EK-0RM80-PG-001 RA81 Field Maint print set MP-01359? I also have prints and or manuals for RP04/5/6 RK611, RK06/07 TUxx and parts for mass bus devices which I will never use. I have no problem selling heads and other parts, but not sure on documentation yet. If i do sell them, the buyer must agree to scan and send copies to Al. I still want to sell off all my q-bus- about 10-15 boxes, and maybe 600 or more boards. All Vax is going. I also have several 8-E boxes, and some boards. also 100 or so non- DEC boards such as Able, CMD, Dilog, Emulex, ETC.

I pulled some RA60, R80, R81, etc. prints and manuals earlier, but left them in the basement when I came upstairs.I will bring them up tomorrow and put out a list.

The service documentation that's available for the R80/RA80 is somewhat useful but lacks detailed technical information, it's a step above a board-swapping guide for service techs, basically. I spent some time yesterday with the schematics (which, annoyingly, don't match my revision of the boards...) and immediately discovered that the optical sensor on the spindle wasn't working anymore -- it was definitely operational when I first started working on it but apparently it gave up the ghost after running for a few hours. So at minimum I need to fix that, there may still be other faults. The sensor picks up light, but it looks like the LED light source on the other end of it is dead.

I'm guessing you mean AA-M186B-TC "RA80 Maintenance Guide", but if not, that's there. (Assuming I've not mis-typed something, I seem to have a later version, AA-M186C-TC, but I've not scanned that).

I'd completely glossed over eBay even though I'm pretty sure that listing showed up in my google searches. I guess I need to pay closer attention... The price is definitely right -- I'll get that scanned and sent off to Al. If anyone has any experience debugging these, do let me know. (I should also note that there is an R80 service manual on Bitsavers -- I misspoke (mistyped?) in my initial e-mail. It doesn't provide a lot of details on the drive's operation and I was hoping the RA80 or RM80 manuals might be more detailed...) Thanks again, - Josh

Looking for DEC RA80 (or RM80, R80) service manual (EK-ORA80-SV or similar)
Hi all --
I have an R80 drive in my VAX-11/730 cabinet that I'm trying to get
running. Symptoms are: most of the time when the Run/Load switch is
depressed, the drive will begin spinning up for 1-2 seconds (sometimes as
long as 3-4 seconds) and then stop, faulting with error code 01 ("Spindle
Timeout Error"). Every now and again it will spin up and go ready -- the
other night it ran for several hours, long enough for me to get a dump of
the disk with no read errors (*).
I've checked the usual -- the motor and the spindle spin freely and the
belt is good and tight. Connectors have been cleaned and reseated, as have
socketed ICs. Power supply voltages are OK. The motor start cap tests
fine. I'm getting pulses from the optical spindle sensor. I suspected
that the brake might have been slowing things down during spin-up as it was
a bit noisy (due to some light corrosion), but the spin-up error persists
even with it entirely removed.
I haven't been able to find the actual service manual for the R80 (or the
very closely related RA80 and RM80 drives). Anyone have a copy stashed
somewhere? Anyone have any debugging advice?
Thanks as always,
Josh
(*) The drive contained a 4.3BSD system used to run a bbs and uucp relay,
"Darkstar 730" out of Beaverton, OR. Looks like it was last run in the
early 1990s. Now I just need to track down the owner :).
