The most "fun" I had like that was when working on a contract with Lennie
Rosenberg's brother Ted.

Ted had spec'ed the hardware, using some really cheap terminals with an NCR
Tower.  The terminal recognize the code to switch output to the printer,
after sending it through to the printer!  This would put the printer in
something like 6in per line (not 6lpi) mode, resetting things like pitch.
I had to hack my "C" code to keep track of the printer state, resetting it
completely after sending the printer-on code to the terminal.
