HP-65 - 1601A03250 - Compatibility Issues ? - Advice needed

Hi Tony
The part numbers are different
The sense amplifier is different
If you look at the last four pictures of the album you can see the differences
The original one came with the unit
The final one we had as a spare and is older (we think)
Definitely pcb release is different and the sense amplifier is different
Since we didn’t take any measure we cannot say if the original magnetic head was working or not ...
Take care !!!
