HP97 The journey begins

[teenix]

Thanks gentlemen for the kind words, much appreciated.

I have begun work on the 97 again. I fitted the board to the calculator and made sure all the wiring fits properly. The printer ribbon cable is off by 0.050 inches when it lines up with the removable socket assembly but that won't matter, there is some room to spare.

I next want to enable some test code to verify the motor and print head output is working properly with the 2 processors before hooking the heads up to power. I have enabled some protection features which will shut the PIK processor down in the event that something happens that shouldn't. Hopefully this will make sure the print heads and motor are always de-energized if this occurs.

cheers

Tony
