I was a poor college student and had access to engineering samples from a local manufacturer. Discarded parts gave me twin 15" LCDs for free in the mid 00's. Also, to see if I could. It was a fun challenge. These are different revs of a controller that were outfitted in several slot machine prototypes. They gave me many years of service. I probably still have inkjet prints of the pinout and signal diagrams, somewhere.
Seems like a fun project to me too. It also seems like things have changed since the turn of the century, with regards to interoperability.
Oh, things are way better now than they were back then. I'd still confirm via documentation that the interfaces are compatible :)
I retired from embedded systems design and design-for-manufacture a decade ago. Reading datasheets was most of the job. This doesn't look too daunting. It's a single interface between two readymade components. I've identified where some issues might come up, and there are probably some that I don't know about yet. Still this seems less like building a circuit around existing ASICs and more like hooking up stereo equipment to me.
