6116 2K x 8 static RAM pinout
DIP-24. 2K x 8 static RAM.
A 2K x 8 static RAM; the stock RAM on the HERO 1 and HERO Jr. HERO 1 has two (U416 at $0000-$07FF, U415 at $0800-$0FFF) on the retained VSB rail during sleep. HERO Jr has one at U203 and takes 8K parts in U204/U205 for BASIC; its supply jumpers (J202, J204, J206) decide whether RAM keeps its contents during sleep. A bad bit shows as a program that fails in one place.
