George, Are you talking about the 802 (which someone said is a terminal) or are you talking about the computer? (model number ???) If you mean the computer then I listed it but I wasn't offering. It's still at the store. I was hoping they might turn up the computer. If you need a copy, I'll see about getting it and making you a copy. If I don't find the computer sooner or later then you may end up with the original. If you mean the terminal manual then it's also still at the store but I don't want it so if you do then let me know and I'll see about getting it for you.

OT: SoCal TRW Swapmeet

by jpl15＠netcom.com

Another month whizzes by! But, what fun! The TRW Ham Radio Swapmeet is this Saturday, 30th January, at the TRW Facility in El Segundo, CA.. from 07:30 until 11:30 hours PST. Any Classicmp denizens who will be in/around the SoCal area on saturday are invited to attend. Afterward, I am planning on brunch at the local eatery, right after Marvin gets done taking 1st place in the ham transmitter hunt contest. (again) Anyone interested in getting together at/after the Meet, or who wishes to use one of my two prime spaces to sell some Vintage Computer gear.. respond by private e-mail for further info. Or, on second thought... never mind. There's never any Good Gear there, anyway... nothing at all. Please sleep in. Wash the car. Walk your ferrets... I want all the Goodies for me...... :) Cheerz John

Televideo 802 computer?

by edick＠idcomm.com

It seems to me that the 802 was a televideo terminal with an integrated workstation. These worked in conjunction with a server unit to run an OS called MOST, I believe, and I have a couple of the server units, the number of which will occur to me when I look at one again. These were fairly late technology, using 64k DRAMS and a 4MHz Z80A. The servers had four or five serial ports using Z80 SIO's and either 10 or 20 MB winchesters to go with their 5-1/4" floppies. They used the WD1000-series HDC, which used an 8X300 microcontroller (I2L technology, Harvard architecture) and the WD1000 5-chip set. I always admired the packaging technology, which was first rate. I have to believe the workstations were up to the same standard in convenient packaging. Televideo was late getting into the desktop workstation market, but did it in a big way with these numbers, as they had all you could want. The OS was purported, by some users I knew, to be quite a bit superior to MPM, which was quite established at that time (late '70's, early '80's). If anyone is interested in the server units, I can make them available, less drives, and possibly a couple of SIO/2's which I scavenged years ago, for the packaging/shipping cost.

Reiability of wrong media (was: is out of 5-1/4" diskettes

old IMSAI hardware

by edick＠idcomm.com

I've got a couple of old IMSAI parallel interface cards, one with two 8255's on it and one with 8 8212's and a bunch of LED's. WOuld anyone have information about these babies? I've had them on the shelf for about fifteen years, thinking I might actually use them for something but have never bothered. I believe I even once had the schematic of the 8255 board, which has two 50-pin edge connectors with the I/O signals and a 26-pin between them which apparently bears some of the control signals from the bus. Unfortunately, I've lost track of the doc's. Anyone have information, e.g. schematics switch settings? Dick

IBM PC-JX (was: Reiability of wrong media)

by guerney＠uq.net.au

Fred Cisin wrote: >The PC-JX is NOT PC-Jr. >Although there are a few superficial similarities, and many of the same >letters in the name, it is a different machine. Among other things, the >JX uses a 720K 5.25" drive. I think it must be a derivative of the PC-Jr design. With no disk in the drives, it boots up into a 40-col screen with IBM PC Jr BASIC Version J1.00 copyright IBM with 42646 bytes free, all white letters on black background. The initial boot screen is a multi-colour rainbow affair with 64K written at the bottom left. The system box has plugs at the back for keyboard, monitor, RS-232, 2 joysticks, printer, audio, cassette and light pen. My unit has a white 5.25" drive with "360K" written on it in pen - so I guess this is only a 360K drive, but is probably a replacement as I doubt IBM would have clashed the colour scheme with the rest of the black system.
