Something like this was going to be my suggestion, too.  The original 
request was to archive the source files, not the disks themselves. 
Virtually every modem-type program (MODEM7, for example) has at least 
XModem, and of course there are tons of options for the PC end (PuTTY seems 
to be a popular choice).

Hopefully there's some serial port in the system, even if it's not the 
console.  And you do remember how to write 8080 code and make CP/M calls, 
right?  Worst case, since it's "Source" you're trying to archive, would be 
to write a simple program that just reads a file and blurts it out the 
serial port, with no handshaking at all.  Running a serial capture on the PC 
would probably have very few, if any, errors.
