The key layout was given as a mock up in an earlier post in this thread 4,. The top keyboard row is unused for the HP2x and HP3x series. Except that some of these keys are used to select a different calculator model. 5. No, they will be supplied or assembled if required 6. They will be complete. I am going to try and make the board sit in a freely available small plastic case, but I won't be supplying them as the end user might have better ideas. As an update... I finally figured out how the HP29C and HP34C manage their constant memory functions and have programmed the PIC to mimic the operation. Both seem fine. cheers Tony |
