I'm hoping that there is somebody on the list who can help a brother out. I need some kind of basic terminal, preferably something VT-100 compatible, but I'll take what I can get. The screen can have a little burn-in, all that is really important is that it is legible and the keyboard functions, and that I can get 9600 baud serial out of it. Oh, and there's another catch. It needs to be somewhere within an 8-hour one-way drive of eastern Montana (that means Denver, SLC, Spokane, the Dakotas, Alberta and Saskatchewan, etc), or somebody willing to pack and ship on the cheap. I'm hoping to get away with around $100 (not including gas and/or shipping) E-mail me off-list (of course).

software (actually anything classic computer related) directory

Think of this as something like ANSI X.12 (Electronic Data > Interchange). Seth would probably be better qualified to talk about this, but there is an exchange protocol in LOCKSS that may be useful for this, though it is geared more towards electronic copies of documents, including province, access rights, etc. in a distributed content environment.

beware: "Microsoft BASIC" paper tape on eBay

by aek＠bitsavers.org

> did you try emailing the seller and say that? Of course I did, prior to posting the classiccmp message. I received no reply, and the auction is still there, unmodified. Would it have been better not to warn potential buyers on this list about it?

Board ID?

by dbetz＠xlisper.com

I have a qbus board that I'd like to identify. I think it's some sort of SCSI adapter but I don't know if it will support disks or if it is "tape only". The board is labeled "TD Systems (c) 1987 ASSY 210-00031". In another place on the board it says "211 00031 REV E". It has a ROM on it labeled "Viking Q/B A4.1". Is this a Viking SCSI adapter? Can anyone point me to a manual for it? I've already checked Bitsavers and Manx and haven't found it. Also, if it is a SCSI hard disk capable adapter, does it have an onboard boot that will work with a PDP-11? Thanks! David

beware: "Microsoft BASIC" paper tape on eBay

by aek＠bitsavers.org

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=230107368051 You can read the first dozen bytes in the picture, which are 7 bit ASCII, starting with 1010000 1010010 1001111 "PROCESSOR TECHNOLOGY BASIC" most likely 4K Proc Tech BASIC, given the tape length.. Jim B. could probably confirm that.

Hex Keypad

by dm561＠torfree.net

-----------Original Message: Date: Thu, 22 Mar 2007 07:53:46 +1100 From: Doug Jackson <doug at stillhq.com> Subject: Hex Keypad On the subject of Blinken lights and toggle switches, I have had difficulties finding decent mechanical keyswitches to use for projects. Essentially, I need to make a hex keypad, with a couple of extra function keys. I know that now we would simply get a membrane rubber thing made up, but once upon a time, I would purchase 20 mechanical switches, and solder them to veroboard. Sadly, I can't find a source of these switches any more..... Same applies to ACSII keyboards - I am fully aware that I could get a PC keyboard and a microcontroller and have ASCI out - but that is 'yet another pc keyboard' Any ideas? Doug --------------Reply; Let me know off-list if you can't find what you need; I've got several boxes full of old keyboards etc. (including an APL keyboard, although I can't recall what that's from ). mike

Crossbar and NeWS questions

by jonas＠otter.se

The Burroughs B5000/6000/7000 series mainframes used crossbar switches to interconnect CPUs with memory and I/O processors. These machines were introduced in 1961 or thereabouts. Jonas Otter

Don in Tucson

by dm561＠torfree.net

Does anybody have a current email address for Don in Tucson, apparently no longer at THX1138 at dakotacom.net (or are you reading this, Don?) mike
