In which I swap out driver ICs to get a Compaq Portable 386 gas plasma display working again. I'm pretty sure the Compaq Portable III uses the same screen. Probably a lot of portables that use a 640x400 display use one or something very similar.
These screens are Matsushita (aka Panasonic) part number MD400F640PD5
Parts I scavenged from the parts screen are:
SN751518 - PNP Open Collector outputs, used for Column driver
SN751506 - Open Drain JFET outputs, used for Row driver
