HP-97 keyboard problem

[Dave92F1]

Thanks. The connections look good all the way to the gold traces on the keyboard PCB.

I'll check the voltages tomorrow, but probably it's the PIK. Sigh.

Eventually I'll post it for parts on eBay; I'll post a link to the auction in case somebody here is interested.

Other than that one problem, it's a good looking calculator (esp. after I spend several hours today cleaning it...).
