- Hello!
-
- I have written a prg for the Amiga and the C64 for PARALLEL communication.
- It uses the 8 bits PB0-7 on the Amiga (the ones connected to the parallel-port)
- and the 8 data-bits of the USER PORT. A cable must connect the PB0-bit of the
- AMIGA parallel-port to the bit 0 of the C64 USER PORT and so on.
-
- PB0 PB1 PB2 PB3 PB4 PB5 PB6 PB7 -Amiga parallel-port
- . . . . . . . .
- | | | | | | | | -My cable
- . . . . . . . .
- D0 D1 D2 D3 D4 D5 D6 D7 -C64 parallel-port
-
- The Amiga-program (called FT), should be run as a backgnd task.
- Start the C64 program, choose source-computer (computer to transfer FROM),
- enter the source-filename (the C64 will look for this file on unit 8, but
- the Amiga can be given a full path, such as df1:fromC64/data/this_file).
- Then just enter the destination file, and the transfer will start.
-
- Ex:
-
- Choose source-computer (A)miga or (C)64: C
-
- Source-file: Data (This file must be located on the diskdrive unit 8)
- Destination: df1:data
-
- Transferring...
-
- Operation succesful.
-
- The Amiga-program FT will recieve the file 'Data' and save it as 'df1:data'.
- The C64 program will tell you if the transfer was succesful. (I have never
- discovered an unsuccesful transfer so far).
-
- !You have to find out which pins are PB0-7 and which are D0-D7 on the ports.
- I don't remember that right now...
- !The Amiga-program is accesing the hardware directically. Be sure no printers
- or other parallel equipment is attached before you start the program.
-
- The only problem is the cable. You have to make one for yourself.
