Hi everyone,
I just finished building the serial I/O board. I plan to use the USB port to transfer CP/M programs between my s100 Z80 system and a PC. After some searching I found a comment from Rich Leary (?) about his modifications to USBGET, which transfers programs from the PC to the Z80 computer under CP/M. He made the program available as USBGET.Z80. I downloaded the program and compiled it. It works great!!!
However, I have not been able to locate a program, probably called USBPUT, that will transfer a program from the Z80 to a PC. I did find PCGET and PCPUT but these programs are setup to work with the serial I/O RS232 of the Z85C30 SCC.
I am hoping that someone has already developed a USBPUT program. I am not good at assembly language- it has been over 35 years since I did any of that type of programming.
Any suggestions would be great.
Thanks,
Harold
