RE: HP-65 more on the card reader
In the scheme I have these looks like Inductor modules, which could be responsible for some noise.
Again, we have some spare parts, but I would find extremely unlikely that on both keyboards these are giving exactly the same fault.
It may be worth to shield the carder reader amplifier to see if in this way it is protected from interference.
What do you think ?
