> Speaking of old HP minis, does anyone have an HP-3000 in their > collection? CHM has a Series II, Series III and a model 44. Finding MPE that will run on these is the problem. There has been talk of a classic 3000 simulator for a while, but I've not been able to find early enough software releases for the machines with good hardware documentation. The 4x series machines have a console processor is a HP proprietary microcontroller unlike those that came out of Fort Collins.

HP HP-2117F on ebay

by steerex＠mindspring.com

>>10) Two microcircuit boards. I happen to REALLY like these. If anyone buys this sytem, I'd be willing to pay for one or two of these cards :) Jay, I have 4 or 5 complete HP1000's and a bunch of spare boards. I wouldn't offer them to just "anyone" but, if you need a couple of microcircuit boards, I'd part with them for the cost of shipping. If there's any other boards that you "REALLY" need, I might be willing to part with some of them as well. See Ya, SteveRob

Matrox cards (including 220, G100, G200 and G400) have a fully programmable dot-clock, so they should be able to drive it. They'll drive a Commodore 1080, which is also a TV-rate monitor -- I just tried it. Of course, you won't get a valid display until the OS comes up and sets the video mode. I believe there's a tool to flash the video BIOS so it'll power up in the desired mode, but then you won't be able to use a VGA monitor with that card any more, unless you flash it back. -- Adam

History of EDA (electronic design automation)?

by Bob.Adamson＠sli-institute.ac.uk

To add a twopennyworth to the thread, I used a transient analysis program (a bit like Spice for those who are familiar) around 1970 to help in designing MOS integrated circuits. It was called TRIMOS, written in Fortran for the PDP10 and also run on a local university's ICL4130. I had a much-reduced version which I translated into Focal and ran (if that's the right word) on a PDP-8/I around 1971 which was OK for working out DC operating points. The same company had some layout tools again for MOS ICs called IIRC Lady Jane which ran on the 10. This fell into disuse when Calma brought out their DG Nova-based GDS1 system somewhere around 1973. I wouldn't want to go back though. Bob Adamson

Looking for old VMS and Ultrix releases

I have a list of tapes of which I have little knowledge. Currently I cannot (easily) read these tapes. Is there anything of interest. I think they are all for RICS.

TI Silent 700 models

by adamg＠pobox.com

>Did any model Silent 700 ever do "true" lower-case, with descenders and >ascenders, as opposed to small-caps only? On a printout from my TI terminal, the tails on the lowercase y and g do extend below the baseline, but not into the line below. The uppercase O is weird, though -- it's rectangular. According to my notes the terminal is a Silent 700 Model 707. It's in storage so I can't look at it now. It's one of the smaller ones with a direct connect modem. I can scan the printout if you like. -- Adam

The power supply of my vax 3900 is making a weak squeaking sound

by tshoppa＠wmata.com

> It is on the CPU side. It sounds like there is a high voltage leakage > problem. You turn it on, and it goes "squeak squeak squeak squeak"? Maybe the LED on the supply is faintly blinking at the same rate? This is the symptom if there isn't the required minimum power load in the Q-bus backplane. The power supply begins to start up, doesn't see enough load, and shuts down, and this repeats every second or so. For minimally configured systems there was a Q-bus card with a bunch of resistors to suck up some current. I think in the box, that one of the two power supplies does the odd-numbered slots, and the other does the even numbered slots. Loads must be distributed to cover both supplies and both supplies need their minimum load met. Sometimes even if you have the required minimum load the power supply will not start up with this symptom. Adding more load seems to help! Tim.

Q22 BUS parity check?

by vax9000＠gmail.com

Hello, I read the Q22 specification (search "Q22 specification" on this page: http://www.chd.dyndns.org/qbus_ide/ ) but the parity check function is still not clear to me. My questions are, 1. Is there parity check when interrupt vector is read ? 2. Is there parity check if IO page is read? 3. What is the polarity of the parity bit? Those questions are not answered from the specification. Any expert here? Thanks vax, 9000
