Hey all

I've been in and out of the classic computer collecting 'circles' over the
past decade and a half, but these days don't have much time to play with the
old toys.  I thought I'd divest myself of some of the items that I've been
collecting and though I wasn't sure if it were appropriate to advertise 'for
sale' on the list, it's probably OK to let people know that I have these
items and that I'll be happy to provide pictures and/or information for
historical reasons.  If you are interested in trade/sale discussion please
contact me privately (andrew - at -  General questions about
functionality/history can go to the list.

I have a DataNumerics DL-8A.  This is possibly the only one still alive,
certainly the only one I've heard of in a decade+ in collectors' hands.
It's a front-panel machine very much like an early Altair - lots of blinking
lights.  Very nice visuals, and appears to work perfectly - I fire it up
every year or so.  Inside it's an 8080, I think - haven't had it open for a
while.  Totally wirewrapped, quite neatly made. and with a low serial number
in the 20s, from memory.  I'll be happy to do images and/or provide
additional information as requested.

I also have a Dulmont Magnum with original manual.  This is one of the very
first laptops, comes with a fold-up 4-line LCD display.  I haven't had this
one working, nor have I tried.  I'd be guessing to say it was functional,
but there are no obvious issues like battery damage, etc.  Weighs a ton, but
for its day it was no doubt a portable marvel.

I do have an extensive collection of early Soviet calculators and handheld
computers.  I collected most of these in the mid to late '90s when building
my site Museum of Soviet Calculators - .  The collection includes a
prototype or two, including one of the only two known MK-98 machines.  The
collection as a whole (100 machines?), but not individually is available for

Finally, I have a very interesting homebrew machine built by a fairly well
known Australian electrical wizard of the '70s and '80s, who published many
articles in the aussie electronics magazines.  This particular machine was a
Signetics 2650 machine, but configured to run 8080 code (and hence, CP/M)
through a software emulator.  The whole machine, including the video card,
was designed and built by the one guy and can be considered historical and

That's about it, really.  If anyone would like pictures and/or further
information on these just ask.
