Please stay safe. That’s the plan. Thanks. We’ve had a fire (when I say fire, I mean wildfire and not what most folks are familiar with which are structure fires) near town yesterday and another one (a bit further away) today. So it’s picking up. To hit the expected 300 for this season, we’ll need about 2 per day! Fortunately most so far have been fairly small (20-80 acres). I know that sounds *large* (our property is 10 acres) but last year’s fire in Paradise was over 150,000 acres (~240 sq miles) and destroyed over 18,000 buildings. It is really hard to imagine the scale of the devastation. So everyone is taking this *much* more seriously now. Today’s fire had 6+ fire engines respond, 2 bulldozers and 2 air tankers respond.

Re: Identification of an HP minicomputer
Thanks Marc. What I’ve done is about all I have time for at the moment. Between work and prep’ing for potential fire evacuations (they’re expecting ~300 wild fires in my area this fire season…we’ve only had about 6 so far…so I expect *a lot* more soon) all of my time is gone. :-( TTFN - Guy > On Aug 15, 2019, at 2:22 PM, Curious Marc via cctalk > wrote: > > I found Brent Hilpert’s site most useful in getting a quick meaning for these > numbers: > http://madrona.ca/e/HP21xx/index.html > http://madrona.ca/e/HP21xx/iointerfaces.html > There is also a very useful series 1000 reference manual that lists most of > the configs and options and cards, I will get to it when I am home and try to > send you a link. > > My experience is that you absolutely have to open them up to figure out what > they actually are.

Re: Identification of an HP minicomputer
I found Brent Hilpert’s site most useful in getting a quick meaning for these numbers: http://madrona.ca/e/HP21xx/index.html http://madrona.ca/e/HP21xx/iointerfaces.html There is also a very useful series 1000 reference manual that lists most of the configs and options and cards, I will get to it when I am home and try to send you a link. My experience is that you absolutely have to open them up to figure out what they actually are. They are so modular and upgradable and interchangeable that the original config sticker rarely matches what’s inside. Actually, I have yet to see one that has a config that matches the factory sticker. Sometimes the motherboard isn’t even the series that the front panel says! Also you need to find out what optional microcode ROMs they are fitted with (extended/virtual memory, fast fortran, vector, scientific, etc...) to know what version of RTE they can actually run, and which boot ROMs are installed. That said they are very easy to take apart, just open front and back, slide out top and bottom covers, slide the cards out, and admire the modular design. They are also very well documented.

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).
