HP97 The journey begins

[teenix]

Hi all,

Some more progress.

The keyboard, display and switches all seem to be working correctly which verifies the PCB design and PIC code for these items.

Next I'll see if the card read/write code I imported from the 67 works.

One problem is that the ribbon cable between the main PCB and card reader PCB has failed due to cracking and doesn't seem repairable. Has anyone found a replacement for these as 0.1 inch track spacing seems to be scarce for flat film connectors these days.

If no progress, I'll move on to the printer which has a whole host of challenges.

cheers

Tony
