... and the Buggy and trackerball. Somewhere I've got a Grafpad too; I think 
that was possibly hooked up to the User port.

I suppose in the PC (as in IBM-compatible) world things tended to get their 
own ISA card (if they couldn't be driven via RS-232). IBM really missed a 
trick in not making the PC's parallel port bidirectional from the start. :-(
