Does anyone have a way to have an RS-232 port on a C64 WITHOUT an extra
cartridge? Can the data lines of the user port be expanded, or the user port
be accessed for the proper signals? Ive seen in C64 books that there are
routines to access the port, but doesnt show how to make a standard port.
There are signal discriptions of the pins on the port, can these be extended
with an edge card connector for the proper RS-232 signals? Ill bet if it can,
it can only go 2400 Baud - close enough.
Ill give it a try and tell you guys what happens.
