Hello to the group,
I know the LCD conversion is nothing new for the 892x series. I recently, thanks to member "DCFluX" mentioning this, added external VGA out the back of my 8920B.
I wanted to share to others that if you want to use the 0.1" header on the LCD board and not wire directly to the terminals here's the part numbers for the connectors and pins.
I also cut the #2 ground pin and inserted a block in the female connector to add polarization of the connector to avoid "oops" in the future.
TE Connectivity 12-Pin Female Connector? p/n: 87456-7
TE Connectivity Female Pins p/n: 87667-3
I then cut a VGA panel mount cable made by Cables2Go p/n: 52096 and took the HP 8920B blank cover plate off the "Option Interface" on the rear of the 8920B and cut/filed/sanded a place to mount the VGA connector to so it looked factory.
The VGA cable barely fits through the LCD/CRT cable port.
I do need to find a native 640x480 monitor now to complete the setup.
The 8920B is by far my most favorite test equipment that I have ever used.
