It's the pinout and the wiring mess that ensues that is discouraging. I also have some intact 40(?)-pin 3½-digit LCDs that I could also use too but not sure of their pinouts or if I want to use them for this purpose -- though the 2-digit LCDs I have a boatload that I could do destructive experimentation on...
BTW, another torture I put on that 3½ display I pictured - I drove the decimal points with square wave DC which is bad. Not for way too long though, but I'd expect it to only affect the decimal points and not the other segments.
