But I could not yet test whether a key was hold down. Also the PRGM/RUN switch was not yet to detect. I needed the whole day to achieve this. Now the HP-19E ACT in conjunction with the newPIK can detect the state of the PRGM/RUN switch, and detect whether the SST and R/S key is still pressed, and I was able to enter my first program. Congratulations for persistence, Bernhard! |
