David,
I picked up about three dozen sealed boxes this weekend,
Verbatim Datalife 5.25" DSDD.
How many do you need?

Hi all ... I arrived here in Mountain View today, up for hanging out tonight who whoever's around and I haven't previously flamed. :)

Get any dumb laptop with a 386 or higher plug in an external keyboard
and load dos, under dos load your favorite terminal emulator. I have
a Modular Systems 486/50 with 32Mb ram brick running W98 to do that.
It has NIC, Parallel, serial, PS/2 Mouse, PS2 keyboard and S7 VGA
in a 3"x5"x12" package and runs off a 12V at 1A wart. It was designed
as a thin (diskless) client but a 2.5" 1gb disk mounts nicely. SIIG
also made bricks that would do well for that also. Bottom line is
there are plenty of small systems with more than enough power to
do a VTxxx. If not you can get PC104 with dualcore. But really
DEC did VT52 with random logic, Vt100 was 8080, Vt220 was 8051
and VT320 used two 8051s. It doesn't need a lot of CPU to do
terminal other than PC display interface and keyboard is high
software overhead. So there exists enough hardware out there that
is smaller than the keyboard and a 15" LCD already.

I have yet to find a PC terminal emulation that gets the keypad near
right. Some fail badly on VT52/100 emulation as well. So when
the OS want a VTxxx I have a VT100/125/320/340/1200 as needed.
Another area where they fail often is the DEC request "what are you"
and often most terminal emulators put squiggles on the screen rather
than handle the ESC correctly.

I'm looking for Digitalk Visual Smalltalk Enterprise for OS/2 including
PARTS Workbench. Let me know if any of you have a copy available. Thanks.
Peace... Sridhar
I'm going to VCF/nanotech thing by plane and I thought this would be a
good way to bring Al some 8" floppies (PLATO system!) to
archive/image, but I wondered if the airport x-ray scanner would do
anything bad to them? I'd hate to damage them on my way to having
them archived...

Just in time for my VCF exhibit this weekend, I've finished putting up some
pictures and commentary on the Tandy Radio Shack Pocket Computer line. The
site is split up into PC-1/3/8, PC-2 and PC-4/5/6/7 pages, with catalogue
number listings, specifications and links. See them in person this weekend!

20,000 for the core or for the mainframe?
How sure are you about it being Burroughs? Wouldn't they be using
U.S. components rather than British?
I know Cadburys bought an ICT 1300 series machine around 1963/4, and
its now in a museum in NZ. It was a 48 bit machine, but I think it
had a much smaller store of 1200 or 2000 words and would have cost
around 100,000 GBP. I have read there was an option to replace all
the 'barn door' core stores with a single store of 4,000 words of 48
bits, though I've never seen one, nor the logic diagrams. I have
always wondered whether it used a full binary decode (using 16384
words to provide 4000 words of usable memory) of the 14 bits rather
than a BCD decode. The 1300s use lots of Mullard components.
Just a small piece of a jigsaw puzzle, maybe not even the right puzzle!
