Get a parallel output A/D and drop it on the printer port - there is 
a parallel port FAQ somewhere that would tell you how to drive the 
port in software.

Unfortunately I have access to a Fluke scopemeter (which gives great 
waveforms on injector signals, coil primaries, etc.) so I don't need 
to rig up one of these PC scopes!

ps. I think one of the Aussie Elecrtonics magszines (Silicon Chip or 
Electronics Australia) had a project to build a device like this a 
few years ago for around $60AUS
