Hi Tony,

It's wonderful to see you analyzing the HP-67 code. I'd liked to have the time today for a look at the code and more comments.

I liked also to have the newACT for HP-67 reading/writing cards. The problem for the chosen PIC processor is, it doesn't have a buffered SPI input (not mentioned in the data sheet!), this makes reading the DATA line in real time extremely difficult or impossible. I hope your hardware doesn't have this problem.
