Just for the record, some days ago I stumbled over physical manuals for the STC 2920, to be specific 'Storage Technology Corporation 2920 Tape Subsystem Maintenance Manual, January 1986'. Volume 1 and Volume 2. Original STC binders. Volume 2 still in unopened plastic wrapping. They're heavy and would be expensive to ship from Norway I guess. But if in the future anyone would need them I may still have them - will try to find somewhere to store them, for a few years at least. But they appear to be approximately the same as is on bitsavers already. Looking at the ebay link in the earlier post, my Volume 1 has a page that looks the same, except that my copy has 'January 1986' printed as well. Volume 2 is called 'Logics'. As I haven't opened it I haven't checked exactly what's in there, and/or if that is covered by the bitsavers scans. -Tor

Al - I have had them with 7 and with 9 but never lucky enough to get the dual headed one... yea... well worth putting online. do you have a link to any sales info on this?

It's in the configuration matrix in the service manual. The 7/9 configuration is read-only. If nothing else, I should pull it out, clean it up, and shoot pictures of everything inside. When Crisis was shutting down, I also bought every 7/9 head stack they had.
Re: Short test programs for pdp 11/34
Hi Devin, if you have the M9312 boot strap card: do you see the console emulator prompt? If the machine HALTs on power-up, some micro coded diagnostic failed => bad! If you see the M9312 prompt, you can use PDP11GUI for further testing Then you can write own assembler programs and download paper-tape based diagnostics. Contact me for more.

Re: Short test programs for pdp 11/34
Thanks, I look forward to trying that out tonight. Thanks for the quick info on how to operate the front panel. As far as the boot card goes, I do have one, but I do not have the vt100 connected at the moment. I. Will get it all set up and post back tonight, using pdp11gui to load the dec diagnostics sounds like the way to go.

The boot ROMs do contain minimal CPU and memory diagnostics. > using pdp11gui to load the dec diagnostics sounds like the way to go. The CPU and UNIBUS have to be basically working for the boot ROMs (and the console emulator they provide via the console serial line) to work; ditto for PDP11GUI. Note that the console emulator will work without working memory, provided the correct boot option (console emulator without diagnostics) is configured on the card that holds the boot ROMs. You won't, of course, be able to load anything without working memory. And the Programmer's Console doesn't require working memory either, and a lot less of the CPU working - the CPU only has to respond to HALT requests from the console. (I had one /04 - very similar to the /34, uses the same front console - which didn't run because there was a bit stuck on in all the registers - but the console still worked.) It does require the UNIBUS not to be wedged, though. Noel
Re: Seeking docs and schematic for Novation CAT modem
Joe - is that the direct connect one of the acoustic coupler? I any event SMECC would love a copy to for our files at the museum here. A side issue there was a Novation coupler - modem... a white one that the phone would sit on. with coupler cups to the side. Does anyone have any photos, advertising, etc etc... on this ?

Just two random pieces that I've been after for my collection: #1. Sun Voyager tote bag. The bag the computer goes into. #2. BeBox front plastic part, and the IO board for a BeBox. Have a dual 66Mhz that is case, PSU and mobo only. Would like to complete it. Thanks. -- Ethan O'Toole

Hi, Joe, No. The original CAT is an acoustic coupler and only does 103, not 212. http://www.computerhistory.org/collections/catalog/102656602 https://upload.wikimedia.org/wikipedia/commons/7/7c/Acoustic_coupler_20041015_175456_1.jpg The Smart Cat came along several years later.

Re: Short test programs for pdp 11/34
Thanks for the helpful quick start information. Plenty of info for me to get started with, thanks. I will post back with the current configuration of the machine. I do have a M9312 card installed, I just need to get the vt100 connected and see if I can get to the console emulator prompt. --Devin On Fri, Sep 23, 2016 at 11:52 AM, Noel Chiappa wrote: > > From: Devin Davison > > >> If the machine HALTs on power-up, some micro coded diagnostic failed > > There are no microcoded diagnostics in the 11/34.

Noel, >> If the machine HALTs on power-up, some micro coded diagnostic failed There are no microcoded diagnostics in the 11/34. I'm talking of that data path check up after power-on. See http://bitsavers.informatik.uni-stuttgart.de/pdf/dec/pdp11/1134/MP00082_1134_Vol2_Sep76.pdf PDF page 40.

Quite detailed information on the logic analyzer trace. I picked up a hp logic analyzer, never used it yet. Hopefully i do not have to get that in depth just yet.

Re: Short test programs for pdp 11/34
> From: Jörg Hoppe > I'm talking of that data path check up after power-on. Huh, I never knew about that. (The manuals don't mention it.) I was just last night looking at the microccode for the 11/04 (a very similar machine - they share the front consoles, etc), and it doesn't have anything like that (see the /04 power on ucode at pg. 130 of EK-KD11D-TM-PRE). Looking through that /34 ucode flow diagram, I discovered that the /34 supported the M[FT]PS instuctions - I thought that was only the QBUS CPU's, etc. Live and learn! :-) Noel
