in the .zip format be downloaded. They must be free. I could probably eventually find them on the internet, but it would take a while. I believe, I still have a simulator around but its a bit cumbersome tpo put in the machine code for assembly language and would like to go to some simulator that does not require machine code.
I'm not implying that my primary interest is a simulator. Software to run a programer is neccessary. I'll have to build the programer myself. A little tricky. The bottle neck might be with the serial port, improvised programer interface. Whats coming out of the serial port is possibly not common knowledge. I've done a simular feet before, successfully. Maybee, I got a little lucky.
