oddly enough it actually works.
pretty cool .

thanks

That one is the Televideo 800 IIRC. 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.

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!!!
Thanks, SteveRob

If I remember I've got 2 manuals at home that are *this* easy to find so
I'll dig 'em out hopefully today......

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.

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).

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.

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.

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?
