HP97 The journey begins

[teenix]

Hi all,

Some more progress.

I have the display module mounted and board populated. The original pins have to be used for the display connections and was a bit if a brain teaser to fit them properly. Have to be careful with this display module as it looks the same construction as the Spice which I have seen a few of the LED digits dislodging from the circuit board.

I programmed some simple LED flash code to test the processor and it is working on the CPU board while plugged into the battery board and turned on via the 19C power switch.

Next up, verify the 19C operational code and LED driver routines and see if the LEDs light up. All new circuitry so fingers crossed.

cheers

Tony
