I'd love to hear from anyone else who has one, or who has worked on
I have one, and not suprisingly, I've also had it apart. They are fairly
modular (although removing the complete typing unit chassis is a lot of
work), you can remove the punch, reader, encolder and decoder very
easily.
A couple of things to watch for if you're taking it apart. Firslty, you
need a set of Bristol Spline keys, the grubscrews have that type of
socket. Secodnly, the carrigage feed escapment has 4 rows of loose ball
bearingsm of 2 sizes. If yoy're tempted to strip this, take great care
(or ask me...)
one. I've downloaded the MIT memos regarding the
operation of the
PDP-1 and TX-0 Flexowriters from Bitsavers, but that's literally all
the documentation I have. I'm not even sure what character set this
one has -- it is lacking the upper-case symbols on the number keys,
for instance, and the "1" key seems to be on the right ("2, 3, 4, 5,
6, 7, 8, 9, 0, 1"). I understand they were frequently customized
with their own character codes, as well.
Mine has separe shift up and shift down character codes that move the
type basket, I think. I've used one that worked in ASCII and which did
the shifts automatically.
The Flexowriter in question is "not working", although it looks like
it's in excellent shape physically. I've become quite handy with
typewriter mechanisms recently (don't ask), so I'm hoping that
The basic mecahsnim, is that of an electric typewriter, with the
motor-drivven roller running across the chassis and snail cams that are
released onto the roller when you press a key, they in turn and drien
ronnf by the roller and then operate the typebar linkages.
