Hi, y'all!
I have a small card with 3 chips. Two are 8K by 8 static RAM
chips (TC5565APL) and the other is marked PAL 20R4AC6N. Across the
top is "(C) 1986 THE ENGINEERING DEPT. INC.". Up the side is
"SR010081".

I did the same thing and got a wealth of information from these guys. They know their shit.
