i n=know you can't see the pin out and its no sub for schematic
but it shows the chip involved in the ROM/MCU interactions.

the SRM and or ROM should have a large data section with stored
patterns for controling stepper motors in precise patterns so i
thought alot of these chips were there for that tasks ... to get
the data for the patterns out to the stepper controlers.

robb

SRM2016 = 2kx8 Sram
D23256AC = 32kx8 Mask ROM
MAB 8031 AH = 8031 Ecu controller
LM393 = opamp or voltage controller I believe

For the rest goto
www.nteinc.com and look them up.
