[sdiy] Those darned Casio chips!

[Rainer Buchty]

While we're on the hunt...

Anyone got datasheets or at least a register interface description
(where appropriate) for

CZ-series:
	upD933		(Music LSI) PD sound generator

FZ1 sampler:
	upD65042G052	(GAB) Sound Generator
	upD65081G012	(GAA) Sound Generator
	upD65012G074 	(GAS) DRAM controller/multiplexer
	MBG653121 	(GAX) harmonic noise eliminator
	MB87186		(DCF) digitally controlled filter

	HD44350 alias HM-350	LCD controller
	HD44351 alias HM-351	LCD controller/driver

I have as much information as included in the service manual, but that's 
about it. Hitachi Japan told me that they indeed have datasheets for 
those LCD controllers, but I would require a signed authorization by 
Casio to get those.

Needless to say what email Casio not even bothered answering :)
