<Blush>  I got my inspiration and motivation for that (as I recall) 
from two things--a pile of GPIB cables for the printer port of a 
Victor 9000 at a local surplus place--and an HP 5-pen plotter picked 
up at the going-out-of-business sale of a Control Data business 
retail store (gives you an idea of how long ago it was).  I also had 
a fresh copy of SuperCalc for the PC and a 5150 with an MDA.   I 
coded the original routine as a TSR that hooked one of the BIOS  
interrupts, so Supercalc was none the wiser.

Funny how some things come together at the right times...
