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...)
Good to know, thanks! I'm really *not* tempted to take it apart to
that degree. I think I would prefer to leave that to a professional
typewriter shop if necessary.
I regard it as a sin to get anyone else to repair anything I own... This
probably explains the number of service manuals I own, and the number of
hours I've spent loking for that little nurgle that's flwon across the
workshop.
Anyway, back to the flexowriter. There are metal cvoers on the punch,
reader, right hand side of the machine (where the carriage return drum
and clutch, and the keyboard encoder contacts are, and behind the
carriage over the relays. All those can be removed (Phillips head screws
IIRC).
You can stand the machine on its back (there are wheels and feet to do
this) mad hten remvoe a couple of screws (may beven br thhumbscrews) and
swing the complete encoder unit out. If you want to remove it totlaly,
the shaft it pibots on is locked by a setscrew in the main body casting,
I think it's a Bristol Spline ont.
The punch and reader cables plug into sockets inside at the back near the
motor. After removing those, the punch and reader units can be removed by
undoing one captive screw in each and pulling them off. There is, IIRC,
a leather washer that acts as a shaft coupling that's loose at this
point, but that's the only problem.
The receive decoder unit, rigth at the front under the keyboard, is held
down by 4 screws. You then have to unhook the output links on this from
the keylevers (IIRC, just lefit the unit towards the front of the
machine. Then with it part way out, unoplug the coonectors inside and
take it all the way out.
All this is 'safe' in that there are no small parts or spring loaded
parts to fly out.
I haven't picked it up yet, so I don't know
what character set the
upper case prints. Based on the photographs, I'm assuming it does
not print any custom computer characters seen on the PDP-1 or TX-0
flexowriters. I think the vast majority of flexowriters in the field
were used for generating paper spam, and would have had a normal
typewriter character set installed, correct?
Unlike n ASR33 or similar, the keyboard on a flexowriter is mechanically
linked to the typebards. You can't type and _not_ get local echo.
So, provided the motor is running, the machine will print what you type,
which makes it trivial to work out what characeters it can print.
Ans while you can, I think, have a key that either doesn't print or
doesn't send anything to the line, I don't think you can (sensibly) have
a typebar that doesn't correspond to a key. in that the receive decoder
actually pulls down the key levers corresponding to the incoming
characters. So every character it can print will correspond to a key.
