Dear Gary:
This is marvellous! I used to work quite a bit on a 3600 in 1968, and it is
good
to hear that there is some form of revitalization for that machine.
Unfortunately I have not retained any software from that time, so that I
cannot help you there.
However, I would be very interested in hearing any information about
the simulator you wrote. Is there / will there be a report on that project
somewhere ? Could you send any description ? How do you simulate
the console ? What do you do in hardware / in software ??
Interested in swapping ? I wrote a simulator for a Siemens S 2002, and I have
a copy of the Algol compiler that went with that machine (no operating
systems at that time, ca. 1960). The S2002 was a binary-coded-decimal
12 digit machine, the one I worked on had 10 K words of core and 10 K words
of drum, and all of that is in the simulator. I have compiled and executed
Algol programs on it - the simulation on a PC runs of course faster
than the original hardware at that time; do you have some timing
estimates for your simulator ?
Very best regards
John G. Zabolitzky
I have been back to the library and grabbed some more books. Again, I will
send to anyone who has a real need/desire for cost of shipping. People who
are already getting books may wish to add some of these to their order...
BTW I'd never heard of CORAL or PARLOG before. Anyone with experience want
to comment?

Beyond all of that this just logically dosent make sense if the intent is to
make sure (just) that a computer gets a good home/is saved from the trash.
If there is already an existing bid on an item, then the computer has
been... *ahem* saved. And publishing an auction just because the current
bidder is a non-member of this list seems a form of discrimination that says
*we* know better.
A service I would more appreciate Marvin, would be something like: Hey,
someone *tried* to sell a system here and couldn't, here's an e-url...
- Wheez: dogas(a)leading.net
OK.. I guess I'll have to appologize for starting this flame war.
Of the lists that I subscribe to, this one has always impressed me by how
cooperative and sharing the members are. Every single day I see members
donating their time, effort, knowledge, and hardware to promote the hobby
of collecting computers. Unfortunately, It's threads like this that kill
the spirit of the group.
In my own defense, I'd like to say: I am not a "conniving, sniviling, wheez
who would probably step on my own mother to get at a cool computer". I
don't think most of the other members would either. I hope anyone that
does, gets exactly what they want!
Secondly, I'm not just the guy with the bull horn. Just check the bidding
history on the SOL and see who the first bidder was! I posted it in the
group because, someone here might want it more than me. If they do, then so
be it...
If you check any of those listings you'll see they have really obscure
terms like "computer" in the description. Now, if that's hidden in a dark
corner where it'll get overlooked, then I'll eat my hat.
Thirdly, there have been a number of times that I have intentionally
skipped a bid when I knew that a member of this group was bidding on an
item. IE: The "Ohio Scientific" thingy that Andrew Davies was looking at a
couple of weeks ago. Sure I'd like to have it but, I wouldn't bid against
someone that REALLY appreciates it.
Fourthly, I for one am willing to share my good fortune with the other
members. I'd much rather see something from my collection go to someone in
this group that anywhere else. When I decide to get rid of something,
you'll (group) be the first to know.
Also, I don't think this set any kinda precedent. I've seen plenty of
similar messages.
Finally, I really do appologize. If I had realized that it would be taken
so personally, I would have never posted it.

That's what makes your actions even more ludicrous to those of us who do
buy stuff on ebay -- the guy at the swap meet with the bull horn is not
there to buy or sell, he just came to advertise using his bull horn!
Ebay advertises their service nationally, and they have a $10 billion
market cap to draw from. I don't think they need your help. If your only
concern is that every orphaned computer find a home, then I think the only
right thing for you to do is to make sure that every one of the contacts
>from whom you get your old computers has the name and phone number of
everybody on this list just in case you're out of town when they call.
You expressed concern when you found that somebody was willing to pay a
higher price than a closing bid. Did you have that same concern when you
paid a few dollars for an Altair or an IBM 5100?

Dual-floppy drive TRS-80 Model 4 microcomputer for sale CHEAP (only $10).
NOTE!!!! THIS IS -NOT- A MODERN COMPUTER! IF YOU NEED TO ASK IF IT IS AN
IBM COMPATIBLE, THIS IS *NOT* THE COMPUTER YOU WANT!!!
Please see "The Catch" below.
Picture available at http://www.plbm.com/trs80.jpg
I just powered it on and it works fine. I have two diskettes; one boots
to TRSDOS and I just ran CDRAG (Sea Dragon) off the second disk, so both
drives seem to work fine, although some files on the disks don't seem to
run.
Notes:
The little sticker on it says 16k RAM. I didn't verify this.
Spare parallel centronix printer cable.
Conformal dust cover included.
See picture at: http://www.plbm.com/trs80.jpg
THE CATCH
I absolutely do -not- have time to take this to the post office or Mail
Boxes Etc, and stand in line to ship it somewhere, even if you're offering
to reimburse.
Therefore, you need to come here and get it. I live in Costa Mesa,
California (in Orange County) and you can email me at trs80(a)plbm.com to
arrange a mutually-convenient pickup if you're interested.
If nobody is interested, it goes to the dumpster in a few more weeks.
DO *NOT* SEND EMAIL ASKING IF I CAN SHIP IT TO YOU. I WILL NOT SHIP THIS
COMPUTER! I WILL DELETE ALL SUCH EMAILS WITHOUT RESPONDING!!

I'm sorry, but I don't know the vital distinction between the two, and
would like to find out. As I understand, Linux is somewhat less secure and
less stable; but what else? And why is Linux less secure/stable?
For anyone that cares, I just got this from IBM .

I read once that all solids are actually just very slow moving liquids.
Apparently the floor of Ft. Knox (where a lot of gold is supposedly stored)
has a tiny but significant amount of gold in it that has seeped in from the
bars sitting on it.
I would think that 100 years could be long enough for the drive platters to
warp slightly (but enough!) or whatever else.

shows some induhvidual selling some IBM family one machine, most likely a 5150
pc with a minimum bid of $500. Gee, i wonder if he'd buy my 'rare' 5140 for
that price... lol.
I don't remember if I asked for information on this computer before.
I'm looking for any documentation or history of this Sherwood Medical
computer. 'A Brunswick Company' is proudly proclaimed on the front
panel adjacent to where it reads Sherwood Medical S-Twelve (which
oem'd this MITS Altair for blood gas analysis).
The Sherwood S-Twelve has eighteen slots, a heavy duty power supply
and the following boards, all made but MITS:
8800 CPU BD REV 0
4K STATIC BOARD REV-2 X4
88-2 SIO REV 0
8K PROM BD REV 0- X2
INVERTER BD 88-IS SH REV 1
88 (SIOB) SERIAL TTL REV 1
MITS MODEM BD
88-MUX REV 1
MITS A/D CONVERTER REV 0
If you have any information about MITS 8800s sold to industry as in
this case, please let me know.
Thanks,
