I made some of these display panels for fun around the year 2000. It's actually quite a neat little circuit with a good visual effect in a small area. The microcontroller is an old PIC16C54 rc-p, which basically means it's not reprogrammable and uses an RC oscillator as it's clock. The initial code would have been tested on an EEPROM based version with a quartz window for UV erasing. It made small software modification quite time consuming as you had to wait several minutes for the chip to be erased before loading the new software.
It’s the prehistoric Supercomputer!!!
where could I get the pinout for this display?
I've always thought someone may have been having a bit of fun with non-native English speakers when they suggested the Kingbright name…
