93Z511PC
2K x 8 One-Time Programmable (OTP) PROM (Programmable Read-Only Memory) microchip. It was originally manufactured by Fairchild Semiconductor and was famously utilized by electronics and arcade companies like Atari in their hardware builds - Component Type: Integrated Circuit (IC) / Non-volatile memory.Memory Capacity: 16 Kilobits (configured as 2K x 8-bit architecture).Programming Method: One-Time Programmable (OTP), meaning data cannot be erased once burned.Package Style: 24-pin Dual In-line Package (DIP-24).Mounting Type: Through Hole technology - The 93Z511PC chip (and its generic designation, the 93511 PROM) was used across Atari's late 1970s and 1980s arcade cabinet hardware rather than home consoles - Le Mans (1976): Atari's classic top-down racing arcade circuit board utilized 2048x8 PROMs for its core program execution memory bank.Starship 1 (1977): This first-person space combat game relied directly on this specific memory architecture layout to handle its complex analog vector-like raster sprite graphics.Tank / Tank II (1974): Early production variants and field-service updates by Atari's Kee Games subsidiary utilized this exact 2K x 8 pin-compatible architecture on the main logic board.Vector & Raster Eras (Late 70s–Early 80s): According to veteran arcade documentation archives, the 93511 / 93Z511 chip family served as the master cross-reference hardware replacement standard for older, failing custom Mostek and Fairchild ROM configurations across early Atari black-and-white vector cabinets
