Hi Lawrence,
Thank you for the interesting pics and videos of the Selectric
terminal. Not long ago I tossed an IBM model 50 electronic
typewriter, which I had had since 1988. Have felt bad about that ever
since. Now I feel worse! :) It wasn't working though, and I didn't
know how difficult it would be to convert it into a terminal. By the
way, the uneven spacing you were seeing is something that it would
do, when the proportional spacing (PS) selector was set wrong.
(Unlike many Selectrics, the model 50 did support PS.)
Also enjoyed your pages on the IBM 360 model 30. Having just finished
reading the excellent book, "IBM's 360 and Early 370 Systems," by
Pugh, et al, the additional coverage of the "baby" model really hit
the spot. Your VHDL implementation of that machine is truly stunning!
All the best,
Steve L.
The ET50 is the same as Carl Claunch has adapted for use as an 1130
console:
http://ibm1130.blogspot.co.uk/ and he's doing an equivalent
project to mine on his typewriter. In fact his whole project
parallels mine, though he is going for the full-size replica approach!
If any one has one spare, in the UK, I will trade for a Selectric
Electronic Composee which seems to only do proportional, unless some one
can tell me different...
.. mind it would be a shame to butcher it for a console..
