Frighteningly, I do remember working with one of those machines. I used it with Lotus to build a database for the company I was working for, before every desk had a computer on it.
What in the world did we fill our desks with before keyboards and monitors?
I learned all about rs-232 ports and serial interfaces trying to get information off an osborne and onto a commercial strength automated printing offset press (!!!)
Ultimately successful but what a learning process. (Love them non-standard serial cables. Have soldering iron will travel.)
