which was definitely an IBM system, or at least fully sponsored by
IBM at MIT. It was either built or maintained in Lincoln Labs, but
it had IBM components and was originally supported by IBM.
- Sure - but IBM had nothing to do with the TX0 - it was a Wes Clark (LINC) design built at MIT's Lincoln Labs.

That kinda makes me want to cry: there were 2 of them in my high school around 1977 from a long abandoned LGP-21.
I used to see them at carnivals for the "handwriting analysis" fake computer! The paper tape reader on the left was clever concealed by the cabinet, lest you see how it was merely printing pre-recorded messages from the paper tape! Perhaps that's a source of Flexowriters as they upgraded to a laptop running any kind of printer now!

really neat machine. I have the protocol information for it and hope to
interface it to something (possibly USB!) at some point in the not too

- About 1970, we had a Friden to create copy for our college newspaper.
Like the ones described, for this one, the operator typed the copy
onto paper tape with a machine similar to a teletype. The Friden
itself, was about the size of a pool table and each time one started
it he had to run four paper tapes through that carried the operating

back further than that. The Colossus at Bletchley used these. You can see one in
the Wiki article here:-
think the KDF/9 (an old English computer) also used these. When I first
started work at an insurance company we had a room full of these. They
were used to prepare the "fancy" life policy documents as the Mainframe
printer would only print upper case and this wasn't "good enough" for
policies. Each girl (there could have been some men, but I don't remember any)
had master tapes for each type of policy. The flexo's had an second punch
attached so the master was read and this typed the fixed wording on the policy.
It stopped at various points at where the girls then typed in the variable
information, policy holder, premium, sum assured etc. As she typed these one
tape was punched for later input to the computer, and the other was used to
print a very posh envelope for sending the policy to the
tapes were not actually read directly into the computer system, they were
fed into a modified key-to-tape machine which created a tape for input to the

would have been the I/O device for the PDP/1 or IBM TX-0 mini. A "cheap"
way to get a real historical item. If it was w/i driving distance I
might consider it, but to ship is very expensive. Still, this is a holy
grail item for
