Whats required to use SIO2PC?
You need an Atari 8-bit computer, a PC computer equipped with a serial port and an SIO2PC interface (cable). SIO2PC will run on the oldest, slowest PC hardware. If you’re using the system to transfer Atari files to the PC, you will also need (at least initially) an Atari compatible disk drive such as the 810 or 1050. I don’t believe SIO2PC will work on an Atari ST emulating the PC.
