It looks identical to the 950 but with different electronics. Downloaded the operating system from a multiuser box. I had several of them. I think I still have one of the Televideo 800 terminals in my storage locker. Paxton Astoria, OR

Bill, Toggled in the program that you sent me and it actually works. Well... It didn't work the first few times because of operator error but, it works now :-) I AM ABSOLUTELY THRILLED!!!

X10 revived - looking for modules, switches, etc

by rhblakeman＠kih.net

Anyone have a stash of cheap excess modules, switches, etc for X10/BSR/etc. I know people mentioned sometime ago that they have bought boxes full of stuff for a few bucks but I don't have those same resources here and am setting up an "easier way of life" for my 64 yr old mother in law that has trouble getting around and forgets to turn lights off, falls asleep with the TV on, etc. I have the 2 way module to the PC and a remote that she can use but wall switches, appliance and lamp modules, etc are still needed. Email me direct if you have excess and want to make space. We can either work a cash deal or trade as I have lots of PS/2 equipment around and some older IBM PC equipment I can trade with. Thanks in advance.

Well, money's a little tight so I'm not getting much computer-related stuff, but I did buy an SGI Indy for my fiancee. ;) She's getting very impatient for it to arrive too.

9-Tracks Drives, especially Overland Data

I don't know anything about that specific drive, but I'd guess the answer is "yes". It might do 3200, which is phase-encoded like 1600, but probably not 800, which is NRZI and needs different electronics (and is actually harder to do reliably, according to some manufacturers). -- Pete Peter Turnbull Network Manager University of York

6502/Z80 speed comparison (was MITS 2SIO serial chip?)

by ajp166＠bellatlantic.net

Cp/m page zero was not required for the os functionality only commonality. The best worst example was the TRS-80 version that had page zero relocated +16k higher to allow for the fixed rom, keyboard and video IO. The aspects of CP/M that would work for a 6502 (or any cpu) are the dynamic filespace allocation and the standized IO interface (BIOS) concept. there are other aspects but the file IO and system IO concepts were the strong points. Ah, and you found the hidden register bug in the z80. You can select either absolutely but, you cannot know which was in use save by some arcane test procedure. Works ok if your building software and enforcing a protocal for use but a multitasking OS where random routines may use one of the other is a mess.

Appletalk h/w

by jrasite＠eoni.com

Does anyone on the list want a pile of Appletalk tranceivers and cabling? I came into a box 18x18x36 of it and would rather give it away than pay to take it to the landfill. This is not Localtalk, but jan-u-wine AT. Round connectors, not RJ11. If anyone wants it for the price of postage, drop me a line. Jim

AN/UYKs

by aw288＠osfn.org

I recently aquired a small number of military Data General clones called AN/UYK-19(V) and AN/UYK-64(V). These are Rolm and Loral machines. Does anyone have any information about them? William Donzelli aw288(a)osfn.org
