     The logo looks like it might be AMD, but ASCII graphics is a little 
     According to IC Master the MSM5056 is an LCD Driver/ALU (!) made by 
     OKI Semiconductors. No other 5056's are listed. I suspect that they 
     are older chips (IC Master tends to not list out-of-production chips). 
     Also AMD is big on memory and CPU's etc. - not audio! I'm all 
     confused. How many pins on the chip?

I have 4 of these MM5056 ICs
The logo is familiar, but I don't know what it is either.

sort of like that.
Anyway, I think they have audio applications, but I'm not sure.
I would appreciate any info.  I looked thru my files and I don't find a 
spec sheet, which I usually get and always keep.
