to change the subject yet again, be careful with that tu58 eugene! the 
rubber rollers seem to have desintegrated into som gum or glue. stick in 
a known good tape and it will be ruined forever.

I have been thinking about making an Arduino sketch to generate the 
blocks for a new tape, but a olivetti programma 101 with quirks and a 
pdp8 with faulty core are standing in queu before that...
