online cross ref hosting found, still need a few other things

by sales＠elecplus.com

A volunteer has come up for the hosting space and software (all open source, Linux) I have the data, and will put it into uploadable formats, and provide templates for others who want to contribute also. I am NOT a php programmer, so a volunteer is needed who will design the site and create a script to do the searches and display the results. Any volunteers? _____ No virus found in this message.

QX-10 / terminal software

by jules.richardson99＠gmail.com

Morning all, I thought I'd try and get the ol' Epson QX-10 running as a dumb terminal. AFAIK, there's nothing on the 'standard' set of disks to do this (e.g. valdocs has the 'mail' program which is aware of the serial port and which I think can talk via a direct link rather than a modem - but I think its functionality is all quite high-level and there's no 'terminal' mode). So... MEX looks like a possibility, and an overlay for the QX-10 seems to be available (although I'm not sure how much work is involved in merging them yet). Does anyone know of any other options[1] which will work with the QX-10's serial hardware? Or, does anyone happen to have a QX-10 enabled version of MEX archived already? [1] does CP/M abstract serial hardware into a set of common calls, or is that outside its scope? cheers Jules

Need Kermit for Xerox 820-II in .IMD format

by xmechanic＠landcomp.net

(Think I may have goofed on my earlier post (excess formatting)) Hiya, Just wondering if anyone has a Xerox 820-II with CP/M 2.2C that already has Kermit installed, that could make a Image Disk of it and upload it someplace? I have Dave Dunfield's Image Disk program, and I've successfully transferred several programs to the machine this way, but I'd like to have a comm program to transfer stuff, as I'm using a modified cable from the existing 8" floppy drive to an old win98/DOS PC for transfers, and I don't like to disconnect and connect those 50 pin edge connectors on and off the boards too many times. I actually have the .HEX files for the machine, but I tried to get them transferred with 22disk, and it doesn't seem to like 8" drives too much (ver. 1.42 or 1.44). I also tried the host terminal transfer, but hex files seem to wreak havoc and don't transfer properly. So I'm kind of stuck between a rock and a hard place. If anyone can help out, it would be greatly appreciated! Thanks. Dave Land Land Computer Service

online cross reference?

by sales＠elecplus.com

Is anyone interested in hosting an online cross reference for components both small and major? I have a fairly large (3000+ line items) of cross reference for hard drives, CDROM, CDRW, NIC cards, video cards, etc for computers and servers that I would be willing to contribute in spreadsheet format. Also MANY hard copy sheets of old printouts for parts that go into HP and IBM servers. Cindy Croxton _____ No virus found in this message.

DG Nova repair etc.

by RolexTM＠gmx.de

Hi all, Tony, thanks for your input, we will check the PSU on Thursday when we get to the machine again. as Christian pointed out, the problem is not so much the pure amount of components but the puzzle game of identifying them since they have been relabled. Whats definitely worse when comparing to out old VT100 is that the DEC manual has one complete definitive service manual that covers all schemes and logic. For our NOVA i failed to find a comparable thing. I have constantly to go back an forward through all kinds of docs. Again I may be unable to find a "real" service manual, if you know any let me know ;) Bruce, I am looking forward hearing from you. It would be great if you come up with anything helpful before Thursday so we can check everything out. Dwight, we are currently missing the exact schematics for our machine. I hope thats where Bruce comes into play. The only real schematics i found were for the NOVA 2, and a quick glimpse showed that the machine is different (at least the layout of parts). None the less we will keep our eye on the clock(s), i guess it will do no harm and make our scopes and logic analyzers happy ;)

networking via SCSI

The machines are configured as multiple initiators and can send storage requests over the SCSI bus to shared disks or arrays. You still have to have another connection (usually Ethernet) for machine->machine cluster communication. While I haven't looked into it much beyond pinouts, DEC produced the proprietary DSSI which, in some cases, used SCSI ASICs - indicating that at some level it was similar (HSD-05 used, I think, an Emulex at either side. Can't check now, but can later). The protocol was different, and cluster communications could go over the DSSI bus between machines. I'm not sure whether the lack of a similar setup for SCSI is more because of impossibility or because Fast/Gig Ethernet came about and there was no longer much of a reason to not use the Ethernet for cluster comms.

HP-UX 10.20 or less for series 800

by saquinn624＠aol.com

I have an old G70 that's currently running HP-UX 11 (I had 11i v1 on it for a while - bit slow for that, and the patches would break it if you weren't careful). Anyway, I have a workstation for all my HP-UX 11 needs and was kicking around the idea of putting 10.20 or 9.04 on the beast to give it a bit more vintage flair, but all of the CDs I have and have seen have been 10.20 for the 700s. Anyone seen a 10.20 for 800 around?

Data General Nova

by RolexTM＠gmx.de

Hi Bruce, thanks for taking your time to answer my mail! Sorry to leave out details, i know how frustrating it is if people forget the important bits of their problems ;) I have (at least sighted) all documentation from bitsavers: http://bitsavers.informatik.uni-stuttgart.de/pdf/dg/ and read a good amount of code and documentation of the simh project (because i would like to build a media emulator for this machine later....maybe) My main problem is that most of the stuff from bitsavers seems to be for newer machines that have a builtin ROM? My machine does not have the program load option (at least theres no switch for it) and i was under the impression that all documentation i found somehow just loaded a stored program for the check procedures. Am i wrong with this? So, in short i did not find any checkout procedure that looked adequate for my machine so i just hacked in some small asm programs that at least ran on the simulator. Actually, the machine runs simple nop jumps at least 1: jmp 2 2: jmp 3 3: jmp 1 If i remember right when running this program it did not even hang itself up (aka you could "stop" the machine). But i prepared the popular "Hello World" asm example to run without RDOS, and it obviously failed at least because of the stuck ACs. I mean, how can you write anything meaningful without using an AC? ;) By "Reset" i mean pushing the reset switch up when pressing down for "stop" does nothing. Again i may be subject to interpret the meaning of STOP and RESET wrong. Clearly this machine is confusing me ;) We will examine the power supply for sure! It bugs me that we did not think of that, since for now we only get to the machine once per week. We may also have the option to take it home though.... Also a friend of mine (which should be registering here soon, too - and is more experienced than me when it comes to electronics) said that the machine was acting strange when he first powered it up after it sat for a week (aka cold). Maybe that points to another aging/heat related/power supply problem. Thanks for clarifying the internal structure of the machine. I was not aware of that although i looked at alot bus pinouts, transfer timings, signal descriptions etc. See above, confusing! The third party board is unidentified for now. We tried to run without it but saw the same error. We also already noticed that the machine runs only with 2 CPU boards and nothing else, at least the PC counts and the ACs still deposit and load. I promise to take quality photos of anything you like once we get back to the machine. I apologize for the bad photos my phone makes. best regards Alex On 02/15/13 18:03, Bruce Ray wrote: > G'day Alex - > > Your e.mail begs many question. > What documentation do you have? > Are you following the checkout procedures in the DG hardware manual? > What "simple programs" can be run? > What does "reset the machine" mean?

3B2 Winchester (ST4376N/CDC Wren)

by saquinn624＠aol.com

Pulled it out, reseated the cables, checked the connections, plugged it into a big enough power supply, and gave it another go. Spun up, head load or lock solenoid clicked, waited about 4 seconds (no sound of seeking), spin down. Sounds like the problem might be somewhere in the head positioning or voice coil/drive.

I vaguely seem to recall I had a DG equivalence list in the 90's. Or maybe confusing it with something else and my memory is just a red herring. Maybe Carl Friend has it? Poly Paks always had lots of house-numbered TTL, I'm guessing floor sweepings from DG :-) When I had to read DG schematics, if the part didn't have a standard number on it, it was usually pretty obvious from pinout or other parameters, what the standard part was. By the time the Eclipse came along, those were just chock full with bipolar PROM's. Tim

PDP-9 Restoration at the RICM

by michael.99.thompson＠gmail.com

Warren Stearns and I have been working on the PDP-9 at the RICM. Yesterday we got the core memory working and started debugging the processor. Quite a milestone for a 44 year old system. All of the operate instructions seem to work. The JMP and ISZ instructions are flakey, even when single stepping. This could be a microcode problem, or a problem with the data multiplexers. It is an interesting machine because it is microcoded with read-only core memory. I am not sure why they used core for the microcode. Maybe just a board with a bunch of diodes would have done the same thing and would have been a lot simpler? I am finding the schematics a challenge because they were created before ANSI or IEC standard logic symbols were invented. Eventually I will understand the symbology. Some of the design is a little strange because you can abuse DTL logic in ways that TTL will not tolerate. Lots of delay lines where you can adjust the delay by changing wire-wrap on the backplane. Lots of pulse amplifiers to improve fan-out and reshape signals. You can read about our debugging progress here. http://www.ricomputermuseum.org/Home/equipment/dec-pdp-9/pdp-9-restoration We need to fix the paper tape reader so we can load some of the diags. We are a long way from connecting the TC-59 and the TU20. I suspect that getting the TU20 working will be a challenge. -- Michael Thompson
