If you have any questions about the true story- I would be more than happy to
help- after all- he was my father-and yes, I can prove it if necessary as so
many people love to doubt that!

If you are talking about the original Mac (the 128k Mac), then I believe
they are pushing the $100 mark if they are complete with keyboard and
mouse. Software, manuals, and guided tour audio tapes will push the price
higher. I'm not a pricing expert, that just seems to be what I've seen
them hover around on ebay and other trading lists.
Of course, sometimes they go much lower... I picked on up not long ago
for $25 shipped to me. I only bought it because it was offered on a list
for a few months and no one wanted to buy it at all, and the owner was
threatening to throw it out.

If you are talking about the G4 Cube, then I would want one if the price
is right. Are you talking about those, or are you refering to the old
classic Macs that have the built in 9 inch black and white screen? (the
old Macs would be more the era of the IBM PC)

Hi, I keep seeing original IBM PCs and Apple Macintosh cubes and
although it's tempting to snatch one for myself this small stuff
isn't really my collector's specialty and I have not enogh room
anyway. But thought that may be some people here think it's
interesting enough to be saved. Since this stuff is shippable
and if there is real big interest I might go through the hassle
and pick such things up ship them.

I have been attempting to get my ASR33 teletype connected to something
and communicating, but so far I have not been successful. I have built
the interface here :
http://www.daedalus.co.nz/~don/computing/20mahack.html , but it didn't
seem to work at all. I connected the teletype to a PC clone running
Linux. I set the baud rate to 110 and tested it with a DEC VT100 set to
110 first, to make sure that the PC was communicating over the serial
port properly. Then, I plugged in the teletype in place of the terminal
with the little kludged adapter, crossed my fingers and turned to knob
to the left. The teletype just rattled, not printing anything, and
nothing from the keyboard printed either. Then, I turned the knob to
the right. The teletype works fine, just as it had before. I can type
on the paper, punch tape, etc. Before, when I was just testing the
teletype without connecting it to anything, I got the exact same
results - with the knob to the left, it just rattles, almost like
"Break" is held down. When the knob is turned to the right, it works
like a very heavy, loud, electric typewriter, and I can punch tape. On
my teletype, the knob isn't labeled, but I am assuming that the knob
must be Line/Off/Local. Does anyone have any ideas on how I can get
this to talk to something? I don't know a lot about teletypes, but I
downloaded the wiring diagrams from pdp8.net, and have been trying to
figure it out. I think I am connecting it to the correct terminals on
the barrier strip, based on what the wiring diagrams say, but then
again, I might have something wrong. One problem is that I don't know
what the Teletype is _supposed_ to do. I have never seen one
operational, so I don't know if the constant rattleing if not connected
is normal or not. There might be something wrong with it that I don't
know, but chances are, it's just something I am doing wrong.
I got suggestions to try using an old Apple Serial card, or an original
IBM XT card to connect the teletype to, but I have neither. I have
several Super Serial Card II's, as well as several early clone XT
serial cards, but I don't think that they will work. At this point, I
don't really care what I connect the teletype to, I would just like to
get it to do something, and verify that it works.
Eventually, I would like to build an RS232 adapter that would allow me
to use the teletype on PC clone hardware, Pr1me hardware, whatever. I
understand that the teletype uses a 20mA current loop, but I'm afraid
that I don't really know anything about current loop technology. Anyone
have some schematics for a true 20mA to RS232 adapter? Something tells
me that this little kludge I found on the 'net probably isn't the best
or most reliable way to do this.
Any help would be greatly appreciated. Thanks!

I came across three DEC Etherworks Turbo PCI 10 Combo cards (DE450-CA)
(vintage 1995, so not quite OT) with manuals and software. Free for postage
(one or all) from Chicago. Reply to r_a_feldman(a)hotmail.com.

Hiyas,
One of the results of today's 400mi drive is a box of Qbus cards that
once were in custom PDP-11 based systems in use at various locations
at Marconi. Most are the usual suspects found in such systems, but
there's also a bunch of weird ones:
- two Data Systems Design cards.. half-height, some RAM, some PROMs
and a fair bit of logic. One 16Mhz xtal. One connector (28 pins
or so)
- a bunch of what look to be custom-made boards, with the Marconi
label and typing. M-12 and such.
Does anyone know more about these?
Cheers,
Fred

Several weeks ago I picked up an early 6800 based computer that came from
an original member of the Home Brew Computer Club. The computer is based on
S6800 prototyping boards that were purchased as part of a group purchase
through the HBCC. I just finished posting a webpage about the computer and
what little I know about it along with pictures of chassis and all the
cards. Please take a look and let me know if you can shed any light on the
computer or it's history or the group purchase. BTW this computer ran Flex
and I did get one disk with it containing Flex.

I would like to know if you have any of these chips available. They are
the direct flash replacement for the 27C512 that I'm looking for.
Thanks
Mehdi Mir
I came across your website and read that you have 29F512 chips. Are
these 28 pin DIP and will they replace the 27C512 eprom? Also if they
are compatible are you able to sell me a few pieces.
Thanks
Mehdi Mir
