HP-67 Reads cards but does not write

[Trevor Gale]

Thank you Tony,

I shall take the HP-67 back into my workshop this evening or tomorrow and examine those switch offset settings. I have a very well-equipped electronics workshop (also with mostly HP / Agilent test & measurement equipment!) and I have performed several repairs on my HP-41 card readers in the past, so I am fairly familiar with the procedure to dismantle the things, etc..

I have never come across this particular problem before, hence my original query - I had not thought of the pressure-switches, so I must be getting old!

I will tell of my results back here when I have had the time to examine the HP-67.
