Re: @Jake
"You got a 24-oh-whatever to connect to a "Pee-Cee"?!?"
It's not all that hard. Most of the 1970[0] and later pre-PEE CEE computer peripherals had an HP-IB/GPIB/IEE-488 option (this can easily be retrofitted if needs be ... usually). Slackware drives most of it quite nicely with a little bit of tweaking, and the various BSDs make life even easier. (This last is subjective ... BSD and I grew up together.) You're on your own if you run Redmond[1] or Cupertino[2] consumerware ...
The fun hack was convincing Slackware that yes, a 1963 IBM 1402 is indeed a valid printer, and gibberish is NOT what I intended to print.
But usually the mainframe peripherals are connected to their respective mainframes as Gawd/ess intended. Some people meditate. I collect and restore big iron.
[0] That's not a hard cut-off. In fact, the line is about as blurry as they get.
[1] How in the hell can Microsoft release an operating system THAT obese, and yet not find room for a couple K worth of print drivers for a line of printers that'll probably happily take a direct hit during Armageddon and come out unscathed?
[2] I rather suspect that Apple's underlying BSDness can be beat into compliance by a properly cognizant hacker. It's on my listie o'things t'do in my !copiousfreetime.
