Erroneous HP-16C

[damaltor]

Thanks, that sounds good!

Update: I have now transplanted the CPU from a (working) 11C into the 16C and vice versa. And voila:

The 16C now works perfectly!

The 11C instead does now the exact same thing which the 16C did before: his program memory starts at 85 and the keycodes are wrong etc. Still, the 11C passes both self tests.

I guess the CPU is faulty. As the 11C is easier/cheaper to replace than the 16C i will happily leave it like that. Still i would like to fix the 11C, but the CPU is almost definitely faulty. I need a 1LF5-0301!
