You can implement the very old Intel hex routine on the ancient computer
data
to convert the programs to ASCII hex. You then 'print' the ASCII hex to
the
serial port. The modern computer can (in DOS for sure) have its console
redirected to com1. It will appear as if someone typing the ASCII hex
very
rapidly to the modern computer. I believe that command was 'mode
con:=com1:'

You can then use debug to convert the ASCII hex back into binary data and
save the program to modern media.

Thanks for the info. I have an original 5150 I can try that on, but
the computers I'm referring to are non-IBM. Commodore 64, Apple II,
TI-99, TRS-80, etc. There's RS-232 style solutions for these. I just
need to implement the connections.

There are 8080 / Z-80 assembly code examples of the Intel hex program, see
if you can find these. Of course, if your program to be saved is in
assembly or
basic or some other printable form, just list it to the serial port.

I did this long ago to move paint formulas for Roach Paint from a Sol S-100
computer to an IBM PC.
