RE: HP-67 weird behavior after reading a card
Just wanted to add that also the unit that was constantly giving an error message
when reading cards has been fixed

After replacing the CRC, ACT, ROM0 with no success
we fixed it, as suggested by Tony, replacing the 47microF
capacitor in the power supply

We have now only more unit to fix and that’s the one that
doesn’t turn on immediately… we’ll keep posting

Thanks again !!!
Edoardo & Alberto
