Multi Calculator Kit

[teenix]

Hi all,

Another update.

After much frustration, I managed to get the HP-10 KISS calculator microcode completed and working properly. I ran the calculator through every problem in the owners manual.

Attached is an image of a calculation example from the manual, with the final result on the LED display on my earlier prototype. There is also a copy of the printout as generated from the PIC which has intercepted the printer data from the HP10 microcode and transferred it to the PC for formatted printing.

Just have to run some last tests and hope all is well before I get a chance to build one next week when I get home.

cheers

Tony
