OK, this is starting to get interesting. I've got a box labled VT100
boards, and it's definitely part of the guts of this terminal (the terminal
works as a terminal).
The terminal has had it's front nameplate removed (probably doesn't mean
anything, they were all this way). On the back is a Digital tag declaring
it to be a VT100-AA. Next to that is a ARC (Agency Records Control, Inc.
of Bryon, Texas) declaring to be a Model ART 01.
The box has the following:
M7270 - KD11-HA - 11/03 CPU Board (dual)
M8021 - MRV11-BA - UV ROM/RAM (dual)
M7949 - LAV11 - LA180 Line Printer Interface (dual)
_Another_ Xebec controller (Wierd disk I think) (Quad)
ARC DFV-11A (Quad)
ARC EIA Switch two 2x5 connectors, 2 switches (RUN/HALT and OVRD/NORM)
1 Vector Plugboard (prototyping board) unused, though the bag has been opened.
I the ARC EIA goes in the options slot on the VT100 board. I think it's
third party version of the card that Megan mentioned in a post today. It
has one of the cables and it's 2x5 pin a connector on both ends.
I don't know if all these board belong to this system or not, I'm pretty
sure that the plug board doesn't.
The MRV11-BA has 256 words of RAM, and 2 1k ROMS
I dug through the manuals I've got, but couldn't come up with anything on
what on earth a DFV-11A is.
Off the top of my head I'd say I'm missing a SLU, and I need a disk controller.

Errr, I was pretty thorough. That's why I set it back down, because I saw
no way to hook a modem to it.

I'll be unsubscribed for a few days to get Linux up and running on my

Nobody kill anyone while I'm gone, OK? ;-)

I don't think ZDNet will post my comments, as mine started with:
Piracy YES. Commodore 64 NOT!
This computer is a lame attempt of a failing PC clone manufacturer to
monopolize on the nostalgia of users and an internet fiasco.
I summed up how not a 64 it was given it has NO 64 interfaces (save for the
keyboard) so you cannot hook any 64 peripherals on it (joysticks, light pens,
REUs, not even 1541 disk drives). And it was merely an encouragement for
owners to download pirated commercial Commodore-64 disk images off of the internet.
Also I added: it may run 64 software, but in no way will it give the owner the
reassurance or feeling that they actually 'own' a Commodore 64.

I think this company is gonna have legal problems from places such as
Broderbund and Eletronic Arts (or more likely CMD, who has alot of ownership
of 64 licenses) if they actually do sell some of em...

So are carburators. You just have to study how they work and learn what
part does what and when. I can make a Carter AFB do anything including
sing. You should hear two of those on a 426 Hemi at WOT!
And if you tweak the engine for more efficiency,

Yes but I can still swap a jet faster than I can burn an EPROM! The big
advantage of the EFI is that it's more precise than a carburator, can
monitor and adjust for more conditions and employs feed back sensors for
even more precise control.

Thanks, Bob. Looks like you may be getting me aboard the
Starship Enterprise after all. I will give it my best shot.
I have the SOL docs somewhere in this nightmarishly cluttered
and disorganized museum I live in. May have TARGET too.
I will take your advice and copy the Trek 80 cassette.
I am curious about one thing. Is the Trek 80 among the
very earliest examples of game software for microcomputers?

Yesterday I picked up an Osborne 1 from the dump. It seems to be in
relatively good physical condition apart from a missing CAPS LOCK key
(which I luckily found nearby). Unfortunately, it had been rained on. The
keyboard was separate from the main unit, and it was full of water. The
main unit seems to be slightly better off (at least water didn't pour out
of it when I picked it up). I haven't pulled either apart yet, so I
haven't seen what condition the internals are in.
Can anyone give me some hints on restoring this machine? What's the best
way to clean mud off circuit boards and electronic components? I'm going
to check the power supply separate disconnected from the main unit, so will
it need a dummy load? Is there anything in particular I should check on
the Osborne 1?
Finally, is it possible to make a boot disk using a PC to CP/M program like
Alien or 22Disk? Where can I find a boot disk image?
Thanks in advance.

I just grabbed a portable terminal called an Informer. It says its from
Los Angeles and is model #207P Serial #55861 -4055
Anyone know anything about it before I try to fire it up?
colan
I am wondering if anyone knows of a good source of Radio Shack
TRS-80 Pocket Computer information. I just picked up a Pocket
Computer (presumably the 'model 1', as it doesn't say Pocket
Computer II, etc.). It is catalog 26-3501.
Anyway, it came complete with the Printer/Cassette Interface
unit.... which you snap the computer into, and the 'expansion unit'
has cassette interface plugs, as well as a small calculator-like
printer. Pretty snazzy little unit. Looks like it has never been
used, and works like a charm. Also, I got the little guy for free!!
Here's my question: It starts up to BASIC. And there are several
modes of operation.... DEF, RUN, PRO, RESERVE. With a little
tinkering, I have managed to figure out that the PRO mode is to
program in BASIC programs. And, the RUN mode is to run them, etc. I
am curious for full information on these modes. I also am wondering
how to access the printer. Say, listing a BASIC program to it, or
printing messages, etc., to the printer. On first guess, I figured
it might use the LLIST and LPRINT type commands such as other early
TRS-80 BASICs did (back in my days of adventure game making :-) ....
but, I have been unable to get them to work. It seems whenever I
enter those commands (or other incorrect commands), I get a
1................................ up on the screen, this seems to be
some type of syntax error.
I guess I just don't know much about this part of the TRS-80
timeline and am looking for any help. Accessing the printer, error
codes, mode explainations, cassette commands in BASIC, etc.
Thank you,
CORD COSLOR
