I have a 19c that is waiting for Bernhard to release a 19c version of his new ACT. I might have a spare original ACT for you then.

The new ACT can be used itself to repair an HP-67, it is a good HP-67 CPU but it cannot handle the card reader. Indeed I promised to develop an HP-19C replacement chip and didn't accomplish yet. The start into a new year should give me a new motivation.

Bernhard

A friend repairing the card reader for one of my HP-67 noticed that after running a magnetic card into the calculator, it crashed or displayed Error. Suspecting the CPU he temporarily put a CPU from another machine and that calculator worked just fine. So the need for a good CPU includes support for the card reader.
