Hi folks, I?ve held onto this collection of manuals for the last 3 years and now they really need to go because I?m having to move house in the next 2-3 months, my landlady is selling up. I thought it was too good to be true being in this house for 7.5 years! The RSTS manuals are V10 (1990) and there's 3 RSX-11M V4 as well as RSX DECNET. I don?t have the time to scan them myself otherwise I would?ve done ages ago. I?m heading past Jim Austin?s place in a couple of weeks? time so if nobody else is interested I can drop them off there if he?s up for it. Cheers, -- adrian/witchy Owner of Binary Dinosaurs, the UK's biggest private home computer collection? t: @binarydinosaurs f: facebook.com/binarydinosaurs w: www.binarydinosaurs.co.uk

It seems When I joined HP in mid-1979, the first week I spotted an IBM Series/1 in a small conference room ... with an IBM repairman. The HP engineers had apparently blown out a memory board somehow while "looking" at it :) >From the HP 3000 viewpoint, we weren't worried about the Series/1. Stan

looking for a 7-track reel tape controller

by p.gebhardt＠ymail.com

Hello Paul, thanks a lot for your hint to the DEC controller. I wasn't aware that the TM11, TMA11 and TMB11 controllers can handle 9-track as well as 7-track NRZI-encoded tape drives. However, all these controllers seem to be very rare in the public out there. Not too surprising considering that DEC TU and TS tape drives themselves are rare and that 7-track tape drives were soon replaced by 9-track tape technology in the early days.

PDP-11 Emulation on VAX Was Re: Alphaservers for free in Athabasca, Alberta

by raywjewhurst＠gmail.com

If I am not mistaken the 8600/50 were the last VAXen to feature PDP-11 emulation. After VMS 3.x the functionality was dropped so it was very short lived on the 8600. Ray

Alphaservers for free in Athabasca, Alberta

A mere 1,000km, South I assume since you gave the distance in miles but I don't think you want a 7 foot rack of ES45s in your living room - the power bill, the heat, and the fan noise would wear on you after a while. Without looking it up, I imagine I am about 1,000km the other way from Kamloops. We could meet in the middle, have a beer together, and trade trailers. :) -- Richard Loken VE6BSV : "...underneath those tuques we wear, Athabasca, Alberta Canada : our heads are naked!" ** rlloken at telus.net ** : - Arthur Black

Control Data Cyber 960 available

by wdonzelli＠gmail.com

I just received a pile of goodies from BT Federal, the last remaining bit of Control Data. Part of the goodies included a complete set of spare CPU boards for a Cyber 960. This means my extra Cy960 is surplus to my needs - I bought it strictly as a source of spare parts. So it needs to go. The world is not all DEC and IBM. Play around with machine that has Seymour's fingerprints all over it. This is an ex-Florida Light and Power box. Mind you, this is a serious machine. It sucks a lot of power, and weighs a lot. 5000 pounds total in three cabinets. Completely over engineered. See the cray-cyber guys website for more specs. This is the CPU only - no disks or tapes, but I could include a DI with it (sort of a channel attached comms box for connecting terminals, printers, and networks). I think the cray-cyber guys are working on getting an emulator working for disk and tape. Software and docs are very available. No goofy license needed. Anyway, available pretty much immediately. Located in the Hudson Valley of NY. Serious machine, so serious inquiries only, please (off list). -- Will

Needed: instruction manual for AVA 103C

by wh.sudbrink＠verizon.net

I just picked up an AVA Model 103C Floppy Exerciser. While it has a few quick tips silkscreened on the bottom of it, I think it would be helpful to have the full manual. I've done a fair bit of googling, but all I've turned up is several repair manuals for other equipment, suggesting the 103C as the ideal tool for testing and repairing their gear.

Various Mac PowerPC, Dec and Sun equipment available in Houston TX

by nospam212-cctalk＠yahoo.com

The clearing continues... I have several system that are free to anyone who wants them before they get tossed. Local pick up gets preference but I'll ship if you are willing to pay for UPS packing and shipping. None of the systems have been powered on in several years and the DEC and Sun equipment is incomplete, see notes below. All systems are as is and include base system only, no monitors, keyboards, etc. All of the Macs came from a company that did audio/video production work. I believe these were mostly used to record and edit audio in a recording studio though some may have been used in their art department for graphics work. Systems include: Mac PowerPC 9600/300 Five Mac PowerPC G4s (Couple of the systems have cases modded for rack mounting) The DEC equipment is as follows: MicroVAX 3100 - No idea what is inside or condition. Case has an opening where it appears a tape or removable drive once was installed but is no longer there. DEC Storage Expansion - Believe this went with the MicroVAX above but not sure, no idea what all is inside or condition. And finally the Sun: Sun SparcStation 5 - No idea condition of what is inside, probably incomplete or missing components but no idea. All the above are offered free for local pickup or you pay to have them packed and shipped. Located in Houston, TX. Contact me off list if you have any questions or want to arrange pickup. Best, David Williams www.trailingedge.com
