qubex qa2000 disk tester

by marvin＠west.net

Is anyone here familiar with this disk tester? I'm actually looking for the operators manual or even better/more unlikely a service manual. I found this while digging through some of the "stuff" I've accumulated over the past 40 years or so. Marvin

I think this is the guy who has the warehouse full of crap in Texas that was going to be scrapped, but now has its own facebook group. If you find and join the group, there are photos of it there. https://www.facebook.com/groups/433516373950693/ Vintage Computer Warehouse Liquidation (Houston) thanks Jim

DIBOL manual

by jnc＠mercury.lcs.mit.edu

> From: Chuck Guzis > Calling DIBOL "COBOL-like" is stretching things quite a bit. OK, so I'll change it to "vaguely COBOL-like"... :-) Seriously, though, there some high-level similarities, and not just the purpose... Noel

Eyring PDOS - paging Camiel Vanderhoeven

by mattislind＠gmail.com

I have a odd TMS9900 machine with floppy drives that would be interesting to get an operating system runnig on. The Eyring institute PDOS looks interesting and I have found a page describing it. https://www.vaxbarn.com/index.php/other-bits/105%20-pdos Unfortunately none of the download links works. I sent a few mails to Camiel but it seems like they might have ended up in the garbage folder so I am trying this public mail instead and hope that it gets through! I really appreciate if the links could be fixed so that I could download a copy. And source code for the boot ROM would be nice. Or is there someone else that have a copy of the manuals and the binaries? Thanks in advance! /Mattis

Wanted: 360k floppy mechs

by technoid6502＠gmail.com

I am in the middle of refurbishing two drive controllers, a Percom At88 with doubler board, and a Percom At-88SPD. Neither has mechs and my search for them has been frustrating. The mechs are like hens teeth online, and when I find them they are insanely expensive. I know there's gotta be a pile of them out there just rusting away. I'd like to give as many as four a good home. Mechs I can use are, in order of desireability: 5.25" 40 track, double -sided, 80-track double-sided, 40 track single-sided. 3.5" mechs (preferably with adapters for 5.25" mounting, have got to have jumpers for drive number selection. Most 1.44's will work on these controllers as 720k drives if the right media is used, or, better, if the drive has jumpers to force the density select. I hate to bother with such a petty thing, but I could sure use some help getting these things running. They are nice drives. I repaired one already, and got it driving a broken MDD210, the only mech I have, but that is so flaky it is of no use other than to let me know my repairs have got the controller working again. Best, Jeff

Mystery chip SCM44506L

by wrm＠dW.co.za

> >Very likely a semi custom or custom memory device, due to the prefix. Armed with that and the fact that pin 1 connects to the leadframe I figured maybe it's something like the 6830 Mikbug prom -- 0V on 1, 5V on 12, data on the left, address on the right. Tried reading it like that (for all 16 combinations of chip selects) but 0xFF throughout. So I popped the lid, stuck it under a microscope. The chip says "MCM6816" which is in fact a 1k ROM. Anyone have more information on the 6816 ROM? Thanks W

DEC Rainbow Univation Docs / Software

This is a bit of a hail mary... I recently won a Univation Intenral Hard Disk System for the DEC Rainbow 100 card, memory and drive. But it came with the wrong docs and no diskettes. Any chance that anybody has anything in this area squirreled away somewhere? Warner

"Older HP equipment of little value"

by sales＠elecplus.com

There are 28 pallets of older HP and Cisco equipment being sold by a broker in Germany. The equipment is located in Hungary. If you can handle taking in a huge amount, and you are in Europe, please contact me. This is not a pick and choose. It is a "take all" situation and will require payment. I do not know the requested value for this lot. I also do not know what the equipment is. A list is available on request.

IBM 5110 power supply schematics?

by mattislind＠gmail.com

It turned out my friend was wrong. The power transformer is most likely ok. But one of the main choppers were short circuited (yes, it is a switcher, again to little info from my friend). Anyway. The chopper transistors were TI made in 1978 but marked T484. Probably some IBM marking which no one has the cross for. I replaced them with nice high voltage high current TO3 transistors The only thing i could get from the original transistors except for the physical appearance was the polarity. With a 5.6 ohm resistor on the 5V i fired up the PSU with a 60W lamp in series with one of the mains leads. Nothing happened on the bases of the switchers until I got to around 190 VAC input. At that point the base went high and stayed there. Really strange. Of course I have no schematics for this IBM thingie. Does anyone have a schematic for the IBM 5110 PSU? I think I really need it to understand what is going on. Tracing it out is an option but then all those square metal canned IBM ICs... /Mattis

A fellow who was putting the air in "Microsoft Tire" (c) is going to prison. Microsoft claims that the air they give free with the tire is not free. You can download the air and install the air and use the air, but noone can help you do it or they will spend 15months in federal prison and pay 3/4 of a million beans in damages for helping you and charging nothing for it but a quarter for the electricity it cost to put the air in. https://www.latimes.com/business/technology/la-fi-tn-microsoft-copyright-20… Jeff

Able document at VCF Midwest

by jnc＠mercury.lcs.mit.edu

This is a long shot, but... There was an Able Computer document at VCF Midwest, and through a miscommunication, it wound up on the 'free' pile. Did anyone here get it? If so, I'd like to try and get it scanned in, and made available. The thing is that documentation for Able products is hyper-rare; we only have those for the UNIVERTER and QNIVERTER, and some preliminary notes for the ENABLE. So if this can somehow be located... And while I'm at it, if anyone has any documentation on other Able products (there's a list here: http://gunkies.org/wiki/Able_Computer which I think is fairly complete), it would be great to get that scanned in too. (Not advertising brochures, we have a couple of them.) Thanks! Noel

Fw: [rescue] Very Last Chance - E6000 and/or parts

by Arno_1983＠gmx.de

Hi everybody, as I don't recall seeing this offer around here (may be just rusty memory on my side however...), I thought I'd forward this for good measure. I'm considering making the 2k mi trip together with my Dad but would do so only as a last resort to save the machine from being scrapped. I think I have some excess CPU boards, maybe a clock board, spacers and PCU/fan boxes from a gutted E4k class machine here (southern Germany) so I might be able to help people looking for parts.

Computer Automation Alpha LSI minicomputer

by dwcar49us＠yahoo.com

Hi, I am restoring a Computer Automation Alpha LSI/2 minicomputer and need some help with software documentation.?I have a?Computer Automation Alpha LSI/2 minicomputer and cards, and I have binary images of the paper tapes, but I don't have the manual for using the software library tools. By any chance does anyone have any of the documentation for the standard software library that came with the machine? BLD, OMEGA, LAMBDA, STP, etc? There was a standard paper tape that had all the basic software for assembly language coding and for loading and linking. The tape images are on bitsavers.org, but the manuals don't seem to be available. The manual was called the Software Documentation Manual.? Thanks for your help. David Carroll
