I’ve had my fun with it: https://tomverbeure.github.io/2022/10/05/Sony-CHM-9001-00-CR... and https://tomverbeure.github.io/2022/06/17/HP16500a-teardown.h..., but they’re just to bulky and heavy for bench top use.
The IR touch screen is awesome though: I reverse engineered the whole PCB into a schematic (it’s a pretty pedestrian LED matrix), and one day I want to do something fun with it.
