Nick Kennedy is the creator of SIO2PC, the hardware and
software combination that allowed Atari 8-bit computer users to use
a PC as a peripheral. In 1989, this was unprecedented, a new way to
connect the little Atari to the bigger world, to the (relatively)
massive storage and speed of a computer running PC-DOS. For the
first time, Ataris could use a PC as storage, RAM disk, and
printer. Nick also created the .ATR file format, which quickly
became the standard for using virtual floppy disks on Atari
emulators.
Nick also created 10502PC, a cable that let you connect an
Atari floppy drive directly to a PC; and AtariCOM, a less
well-known utility that allowed two Atari 8-Bit computers to
communicate using the SIO and joystick ports. And, he created
Atari-based amateur radio tools: a terminal program for packet
radio, and Morse code keyer software, which he and I talked about
in detail in our previous interview.
