HP97 The journey begins

[teenix]

Hi all,

After just half hour of poking around, repairing a few dodgy solder joints and a bent CPU board connector, sill dead.

There was another CPU board in the box, which I didn't hold much hope for as it had no static protection, but on replacing it and making sure all pins were in good contact, it fired up and seems to work ok, accepts and runs programs too.

I set the input voltage to just where the low battery LED extinguished, and no nasty current flow from the power supply, about 160mA (no battery connected), and changing the display from 0.00 to -8.888888888 -88 drew an extra 60mA or so. The chips seem cool and happy, so that seems a good start.

Alas, the printer and card reader are not happy at all, so I think this is where the fun will start.

cheers

Tony
