Hello,
i have a chip from a bally MPU but i do not remember the position i extract it.
The chip says "5A-9903" 7743

5A-9003 is a Williams number, and is 6810 RAM.

Jim,
I know it is williams but the part number says 5a-9903 not 5a-9003
For that reason i am not sure if it is a 6810.
Is it the same 9903 with 9003?
