I just opened up the LCD and took a look at it. The main connector is labeled CN1 (pretty standard), there are three LCD connections, one on the side and two on the bottom. Curious, each of those are labeled U401, U402 etc... and the two bottom ones have a black square on it, where the one on the side has a piece of what looks to be silicon. So, my bet is that there is an acutal IC directly on the ribbon cable that connects the board to the lcd, probably just drivers.
Either way, there seems to be 8 bits going to each of those connectors, and the 8 "bits" that route to the left most LCD connector on the bottom, also seem to make their way to the right connector under the main board connector.
So in all, it seems to be a fairly simple and straight forward display. Perhaps a counter type driver for the rows, and a data type drive for the columns on the bottom.
I'll have to look more at the main board and see what drives those connectors and where those lines go, maybe then I'll have a bit more info.
Too bad there are no useful part numbers or manufactureer information on that LCD. I'm considering building a custom computer board that will fit inside that handy dandy little box. I wish there was some way to contact some rogue employee at Cidco or something.
