Hi,
Is the 'call control unit' -- the electronics
chassis on the right hand
side -- the same?
On *my* 390 there is a slightly different "call control
unit". But I
have several 33s and nearly each has a different ccu. Normally you don't
have to worry about that if you have a current loop device in working
condition. There are also a lot of different wiring options for the
machine.....
where the mechaical bits are normal Teletype ones, but
the
call control unit is very different. It's built on a couple of PCBs (!)
and can handle both RS232 and current loop interfaces.
Hey, that's cool. PCBs
are normal in all CCUs.
It will be hard to find schmematics for that.
Believe it or not, the Teletype manuals for the Model
33 do have cleaning
and lubrication charts for the cover...
:-)
... but there's no information about glueing together broken pieces of
grey plastic.... :-)
