I have been using David Tait's FPP software and his TOPIC programmer with 16F84A PICs with great success. I have just designed a project using the PIC16F73 and would like to use my existing hardware/software. Unfortunately, the 16F73 is not listed and my attempts to get it to work have not been successful. Does anyone know of other software that supports the TOPIC programmer and the PIC16F73?
