At the seminar in Toronto (June 16), we were advised that Firmware v1.50 was released to accomodate the 12C67x which has a different programming specification than others. No mention was made of changes to the programming specifications of the other 12 bit core devices. For older PicStart Plus programmers, the firmware is supposedly available on the website -- download it and burn it into a 17C42 before dismantling the programmer and inserting the newly programmed 17C42 in place of the original.
