manual that came with the jr for cost plus shipping. Cost for PCjr and book

It's a model LT-3200 40 by Paoku P&C LTD. I plug it in and get nothing, no
power brick is used, cord plugs into back of unit. There are no sounds,
lights, or anything when I try to power on the unit.

I forget who (Murray Leinster?) wrote "A Logic Named Joe", which very
closely describes the information explosion of the Internet.
I have just had an IBM 5100 "Portable" computer (circa 1976) donated,
along with a 5103 printer and a 5106 tape drive. No documentation or
software, so could anyone tell me what I have, what operating system it
used, and what kind of tapes?

I've never heard of a microcomputer that used EBCDIC, but there are a lot of
things of which I've never heard. It is used in IBM mainframes and minis.
Here at HUD we have a Hitachi mainframe that emulates an IBM, and it uses
EBCDIC internally. We have file transfer utilities that take care of
translating into ASCII as necessary.
What does it stand for? Gee, it's been a long time. Let's see.
According to the "SAS Compantion for the MVS Environment," it stands
for Extended Binary Coded Decimal Interchange Code. That sounds redundant,
but that's IBM for you.

A number of the 8 series aquired desktop status but never by intent
portable. They simply weren't rack bound.
The HP???? struck me as something portable(toteable) as it was a complete
machine that could be moved be moved from one place to another as a unit.
The earliest thing I'd seen that was portable was a home brew 8080 system
with build in keyboard and TV RF output back in '75 and it wasn't a PT SOL.
Though the core of it was S100 boards from an altair.

What I saw demonstrated at the Science Museum (part of the British
Museum) 5 years ago was a working _difference_ engine. This had a
couple of design bugs fixed (one in the ripple carry mechanism IIRC) and
I don't recall anything about an analytical engine being built at this
time. Has it been done since? Do tell!

I have the PC-10 here, so I knew about this. :) There was also, from
memory, the Commodore Colt and PC-30. I also seem to think there was a
PC-5, but I can be corrected on this. I imagine there were later models as
What was interesting for me was spotting a Commodore MS-DOS laptop
recently. I thought that the only commodore laptop was the prototype C-64
laptop - I wasn't aware that Commodore made any more, even if it was only a
pc clone. UNfortunatly they were asking too much for me, although I would
have considered it if I could afford the machine.
Has anyone ever built a Braille writer out of a punched tape machine? It
seems to me that slight mods (i.e. embossing, not punching) would be needed.
