You didn't list the cards in the rear I/O cage (the IDs should be on the card ejectors). However, if you have a 12821A HP-IB Disc Interface, you could run the standard HP diagnostics, which are quite thorough. They're available here: http://www.hpmuseum.net/display_item.php?sw=567 You'd also need the 12992J CS/80 Disc Loader ROM, if it's not installed (the binary is available at Bitsavers, and the chip is a fairly common 256 x 4-bit bipolar PROM), a $50 GPIB card for a PC, and Ansgar Kueckes' HPDrive program: http://www.hp9845.net/9845/projects/hpdrive/ ...which emulates a cartridge tape drive (among other HP mass-storage peripherals). That setup (12821A card/GPIB card/HPDrive program) also opens up the possibility of running some of the HP disc-based operating systems without requiring an HP disc or tape drive. Without removing the CPU, you can't easily tell which loader ROMs are installed in sockets on the PCB (there are up to four, with the first being a paper tape loader), except by loading each one into memory and comparing it to the binary listings in the 12992 manual. Also, you can't easily determine if any optional firmware instruction set PCBs are installed (they mount to the CPU board via standoffs). Removal of the bottom chassis panel is simple, which will reveal the firmware PCBs, but the part numbers are on the underside, i.e., facing the CPU board, typically requiring their removal from the CPU PCB for identification. -- Dave

Re: Identification of an HP minicomputer
Fun! I have 4 HP minis at the moment: 2116C that was running the last time I checked 2 2114B that are in various states of “not working”. Interestingly the most promising one (e.g. the one that hasn’t had various parts clipped or otherwise buggered) is where I can’t get it to power up at all (not even the fan). So I have to go and dig into the power supply a bit more…it could also be that the power cord is wired up incorrectly since it uses an old style hubble twist-lock that I may not have wired up quite right) HP-1000 M Series TTFN - Guy > On Aug 12, 2019, at 4:38 PM, Guy Dunphy wrote: > > Hi Guy, > > If you didn't see this, it may be of interest: > http://everist.org/NobLog/20131112_HP_1000_minicomputer_teardown.htm > > It won't help you identify your system model, but could be of help with > disassembly. > > Funny coincidence that we have the same name, and similar HP-1000 > minicomputers. > > Sigh... 2019 slips by, and I still haven't returned to that project. > > Guy > > > At 02:52 PM 12/08/2019 -0700, you wrote: >> Hi, >> >> I have sitting in my pile of stuff an HP minicomputer that Iâm trying to >> identify (at least in terms of exactly what it is and what sort of >> configuration it might have). >> >> As far as I can tell, itâs an HP-1000 M-Series minicomputer (that should >> hopefully get us *some* details).

The original M-Series machines were the 2105A and the 2108A (9-slot), which sound like what you have.

Pierre, I would suggest that as you haven't seen one in ages, the price reflects the rarity and the vendor is hoping for a rich collector to buy it. I don't know off hand of anyone who uses one. I know that the 4341 at LCM uses emulated DASD as does the ICL 2900 at TNMOC in the UK which I think has some EDS300 drives https://farm9.static.flickr.com/8314/7939054098_08c37818fe_b.jpg which look almost identical to the CDC drive on E-Bay, there are a few more pics here https://hiveminer.com/Tags/bletchleypark%2Cicl There are people using smaller exchangeable drives such as DEC RL01 and RL02 drives, and the similar drives on the IBM1130 and IBM1800 but those are a totally different ball game...

I am not a CDC CPU expert but I know that various CDC SMD drives, especially the 9762 and 9766 were found on PDP-11s and VAXen owing to inexpensive (compared to DEC) 3rd Party disk controllers (and drivers for various operating systems). The drive mechs were also repackaged and put behind modified SMD-Massbus interfaces and were available from DEC as the RM02/RM03 (9762) and RM05 (9766) but they were DEC badged not CDC badged (colors, labels, etc) so you wouldn't mistake one from the other externally. I happen to have a 9766 (and at least one SMD interface for either Unibus or Qbus) but no pack. -ethan

Would this have been connected to a CDC Cyber back in the day? I noticed that this is in Athens, GA, home of University of Georgia.

Re: Control Data 9766 drive on epay
Well, crap. I got rid of my 2 9766’s and all the packs that I had for them a couple of years ago for nothing what this guy is asking for his. ;-) I probably still have a pile of heads for them (but they’d probably go to the guy who purchased the drives/packs from me). What are folks using these types of drivers for? Media content recovery or just using them as intended?

Maybe the CHM? We don't have one in working condition, and we're unlikely to attempt any work on multi-platter media recovery any time soon. I have three Pertec top-loading drives and several Diablo 30s, but haven't had time to try flux-level recovery on several dozen high archival value targets, including what may be the only surviving Burroughs B1700 packs.

Ah, the *Emulex* TC02. You had me going there--DEC also has a DECtape controller called the TC02. Looking at the TC02, there are 374s to latch data coming from the Qualstar and use the termination packs, but there are also 7438s driving the lines from the TC02 to the Qualstar. Those have no terminators. The TC02 reference manual says that you get run lines up to 30 feet long between the TC02 and formatter. My point is that the driver technology for the Qualstar (i.e. read data and status) is inappropriate for long cable runs. The spec calls for 48 ma OC drivers. --Chuck

Never > had a problem. I stand by my commentary re Qualstar 1xxx drives. They're not up to the task of driving long cables. Who has one such drive with 10' cables operating correctly? Until someone comes up with actual experience with said drives, we're just guessing. I note that my 1260S does have the capability to be used as a Pertec interface drive. I suppose I could re-cable from one of my other drives and test it, but at this stage, I hardly see the point. --Chuck
