olivetti programma 101 repair

[Simon Claessen]

Hello all,

well, i've remade 53 clips for the backplane, but unfortunately things 
do not inprove. Its even wors now. I can get no reaction from the 
electronics at all. I suspect that not only my clips are wrong, but with 
every insert of a card, other clips are starting to break apart.

for now i've shelved the project and I will look at a way to let all 
clips produced somewhere. fortunately, there is a business in bending 
metal not far away.
