- Connect the Apple II serial cable to a Serial-USB Adaptor
$ cd /dev $ ls tty.* tty.KeySerial1
- Load terminal emulation software on Apple IIc
- Use screen to connect and run getty
$ screen /dev/ttys.KeySerial1- Ctrl-A, Shift-: and then exec ::: /usr/libexec/getty std.1200
[robg adds: Definitely not your normal OS X hint, and there are obviously many easier solutions. Still, putting an old Apple ][ to work like this is pretty cool.]
