When I did the goo<->o-ring swap in my HP41 card reader,
two of the coloured wires that connect the card reader
with the pcb came off.

I had thought they were soldered there, but they seem to be just plugged in.
Can anyone give me the correct sequence ?

(top down: red, yellow, blue, orange, black ?)

BTW does anyone have a large quantity of correctly sized
o-rings and can send me some ?

George

At least in my reader, the sequence is the same you posted, I remember it formed the R Y B O K "word". After fiddling with the contacts, I decided to solder them lightly to keep them in place.
