No. the 765 was available for sale in late 1980, CP/M systems were 
3+ years old by then.  Even after that point the 765 was not the 
common part used for CP/M systems.  That a PCism.

CP/M systems were largely a common coperating system a that allowed
for diverse hardware by way of a BIOS that the user or manufacturer
could configure for that hardware.  There were many different disk
systems, formats and in the games space deliberate attempts to make 
the disks uncopyable by standard systems.

What you need is a CP/M familiar person here (actually close to the developer)
in the usa and the data once extracted can be shipped via the internet.
Systems that convert formats are common enough for people that actively 
collect and restore.
