Sometimes the bush league amateur stuff is all that is needed !

It should not be impossible to get a 100$ FPGA board, generate a VGA display,
use a 100MHz flash DC and have 100MHz logic analiser / digital storage scope
for little more then that plus the price of the probe and a few discrete
components.
Like for example here:

100MSPS != 100MHz

Thanks for the link - by sheer co-incidence I was also looking for something
like that, and it looks like a good one too.

Visual Analyser is free. Uses your soundcard as a scope, spectrum
analyzer, audio signal generator, voltmeter etc. Scope has zoom,
trigger, calibrate, screen capture and more.
