Tim,
This email is to respond to your earlier email about having some VGA kit to replace the CRT.
I have an idea. Since all the display section does is to take the signal to be display (y-axis) and sweep the screen with sweep signal (x-axis), I can make up a digitized circuit that does the same thing as what CRT will do and connect the output to a LCD module that fits right into the window of HP 8565A, I can have a cheap solution for replacement of CRT tube circuit.
My idea came from here:
.
About the normalizer part. I am thinking about build up something based on the same design of normalizer in SMD and place the circuits inside the large cavity where CRT is in. I can then have all the functions I need in the same box. I am thinking about changing the weird AUX connectors to some easy to get connectors from Digikey (same pin numbers, same dimensions.)
