Is there anything someone hasn't done? 
Bit-bashing is definitely the kind of thing I had in mind. But the 50-pin connector? My "development system" is a Premium+, so I probably don't have one of those.
I've done a bit of bit-bashing on a dual 8255 interface I was creating long ago (intended to eventually become an SASI / SCSI Controller). Well, it could turn LED's on and off.
Basically, I'm hoping to make a simple, cheap and ubiquitous Parallel Port to i2c adapter and some command line tools to read various sensors and drive devices such as displays and the like.
Why use an Arduino when CP/M will do?
