In case you';re talking about this
http://buchty.net/casio/fz1-simm.html
you'd probably be the first. I never got any success feedback so far,
which either means that noone really tried it or noone trying got it to
work. (And since my own FZ-1 was FBR by "careful" movers about 15 years
ago, I never tried it out myself, either.)

No. It's a custom LCD controller setup, see
http://buchty.net/casio/display.html
for an initial analysis of the protocol.
If that looks familiar to anyone, please let me know. I checked against
a bunch of Hitachi controllers and it's seemingly its own kind (and
recycled from the graphical Casio calculators which introduced this
display setup).
If you want to hook up a contemporary LCD graphics controller, you would
need to rewrite all LCD control routines from scratch (at least print,
plot, cls, contrast setting) and get a proper address/data breakout (as
the existing 6-bit LCD interface is most likely of no use), i.e. hook
the solution into I/O address space. (I hope you enjoy 80186 assembly
language :) )

Re: [Casio_FZ_Samplers] Casio FZ 10 4mb RAM HACK and LED LCD Display replacement
2016-12-02 by Tarkan Sahin
i found a guy who did it. but i he did it on the fz1 and but mine is the rack. i have to check this further and then i will give it a try. but i cant seem to find the right memory chips for this hack....
Concerning the LCD, they guys in the Akai Forums did managed to make a working LED Display for the mpc60 and the S3000 and MPC3000. Which is also using a propietery Controller. So this should also be possible for the FZ?
