olivetti programma 101 repair

[Simon Claessen]

we have one datacard but the rollers in the reader are gone to goo. 
Fixing that is the last thing on my mind at the moment. :-) the diameter 
of the rubber rollers on our version with the geared printer drive 
(older versions had a separate belt) is +/- 12mm.

I've taken the electronics module apart as I want to find out where the 
clock is generated or derived from as there is no xtal on the machine 
and there is no ac from the psu going to the electronics.
