This is not sure-fire, but I've found that if the big label on the back does
NOT have the notice "contains copyrighted code..." that it's most likely an
original version.

Subject: Way to identify original IBM-PC?
Hi,
I was wondering if there's a surefire way of telling if an IBM-PC has its
original motherboard, without opening the case. I saw one at the
Salvation Army today and was considering dragging it home (though I
decided to take another machine instead).
The machine did have a cassette port in the back, with a femal DIN
connector. Is this attached to the motherboard?
The machine also had a full complement of cards in its slots, with lots of
ports coming out of it. And a 3.5" drive that was poorly fitted into the
case.
I'm wondering if I should make a trip downtown sometime this weekend, with
the car.

Well... while it may not improve the price, it may improve the audience...
B^}
While trying to NOT reignite another flame war (which I probably contribute
to), the qualifier on this idea might be that when you post something, post
it with an acceptable price. IMHO that should not be a difficult
proposition for someone who is looking for a good home for a piece of
equipment. If you are just going to relocate an auction, then you are
probably only in it for the money! (boy, am I gonna get yelled at for THAT
one)
What really scrapes my oxide is an approach that I am starting to see more
often in postings in and newsgroups. (it has happened to me twice now in
the last month)
Someone posts an item with an asking price. I respond to the message with
a counter offer. The seller responds with a counter-counter offer that I
find acceptable. I respond to the message with my acceptance and provide
shipping details. The seller then responded back indicating that he has
received a higher offer and that the unit has been sold without so much as
an opportunity for further response.
Now, maybe it is just me... But from my view when responded with a counter
to my offer, we were in the midst of transacting a deal and I should have
'right of first refusal' until the point that either we make the deal or I
decide I don't want it.
I don't appreciate multi-thread dealing going on without being informed.
And it was not like there were any extended delays between these messages.
The entire series of exchanges occurred over less than 24 hours. Very
similar for the second occurrance I mentioned above...
BTW: a HERO-2000 auction just closed on eBay for $4027.78... (sheesh!)

Hi
Yes a reality, and a nic name I got from some friends.
I don't remember the key stroke to open a new file or to save to disk, but
it had some thing to do whith function key 3 or 4 I think remember it's been
a while, after the function key a letter I am not sure whitch letter opened
a new fiel whith a prompt for a file name: you typed in the file name
pressed enter and you wore in the word prosessor, and could type what ever
in.
I used it mostly to write messages on from calls ect, I would leave it on
all day, and get some help later on some one would read it back to me so I
could braille it out.
The drive was ten MB and had Wang dos on it and the word prosser was also
on it.
The monotor was a Wang monotor, I don't know if they are still available.
This Wang I had was baught at a flee market, a fellow had 20 or 30 of them
he was selling complete for $25 about ten years ago.
A friend saw it and snagged one for me he knew I was interested in
computers, and thought it would make a interesting birthday present for me.
I sold it eventually because I couldn't het a sinthasiser that would work
in the card slots, they worent ISA or any thing like that, not sure what
they wore.

If you don't find a use for it, I'd be interested. I remember some ads from
SD Sales in old issues of BYTES's, but the single board Z-80 computer didn't
have any S-100 connectors, etc, IIRC.
I enjoy and would like to
a) figure out the monitor code
b) find out what EPROM it would program. If the circuit is simple, it
probably is for a 2716. What size EPROM is the "Z-BUG" in?
c) Find out if it can use or test various S-100 boards, depending on what
signals are provided. Would be an upgrade for my simple S-100 tester.
Thanks,
-Dave

There is C and H on Cororado Blvd. in Pasadena, but don't know if they have
anything. There is also ECSC in Gardena, if you want to go that far. Their
web site is www.eio.com
The best bets seem to be the Ham radio swap meets, (not the commercial
computer shows). The only one I know of on July 4 is in Santee, near San
Diego. I enjoy the TRW meet the last Saturday of every month. I don't know
if there are any gemeral or antique swap meets this weekend. Once per month
there is one in the Rose Bowl.
Wish I knew other places.
I plan to visit the San Jose area in a few weeks, are there any suggestions
for looking there? I know of Haltek in Mountain View and Halted + Weird
Stuff in Santa Clara.

Once upon a time in the early 80's a man named
Bill von Meister started a company called Control
Video Corporation. (Bill von Meister had been one
of the founders of The Source which was bought by
Readers Digest) CVC started a service for Atari
2600 users called GameLine. Users would plug a
large modem cartridge into their 2600 and could
download a game and play it until they turned
their 2600 off. This service was kill by the Video
game crash of '83.
Next they developed proprietary modems for the
C64 and the Apple II and started a service called
MasterLine. Same thing, you could download and
try software before buying it. This is when I
started with CVC (about the end of 1983 I think)
MasterLine lasted 3 months.
Next they acquired the software from a small
on-line service called Playnet and in 6 months
launched QuantumLink (Q-Link for short). At
some point in here they also changed their
name to Quantum Computer Services. Q-Link was
a C64 only service.
About 1987 they started AppleLink: Personal
Edition (not to be confused with Apple's tech
support service AppleLink) for Apple II, and
IIgs. And about the same time they also started
PCLink running under Tandy's DeskMate GUI.
This is also the point where I left the company
and moved to California. In California I ported
Q-Link's Rabbit Jack's Casino Games to run on
AppleLink but other than that I lost track of
the company. I believe they changed their name
and the service's name to America On Line in 1989.
