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.

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......
:)

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.

Hmm... then why does a chkdsk a: on a '1.44' drive and disk return
the following:
- - - - -
1,457,664 bytes total disk space
512 bytes in 1 directories
1,185,792 bytes in 20 user files
271,360 bytes available on disk
512 bytes in each allocation unit
2,847 total allocation units on disk
530 available allocation units on disk
- - - - -
You had better check *your* math!
2 * 80 * 18 * 512 = 1474560
Sure looks like at least 1.44 Mb to me!

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?

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.

You know that the german "elektor" had a series of artikels about ?
They called him "scampy" or something similar. With board, cpu card,

I am finally having a clear out of my garage, amongst the stuff I have
there is
A Digital pdp11/70, including processor, 64 ports (emulex controllers)
Kennedy tape deck,
Processor has 4mb memory (Systime), there is a unibus expansion box
which contains a disk controller, and the 2 x 32 port emulex
controllers.
I dont have the disk drives (which were 2 x Fuji super eagles). I have
the software tapes, manuals etc. The sysgen listing and patches for
Rsts/e 9.3.
Is this worth out, or should I finally consign to the skip. (btw all the
above is in a systime double width cabinet.
