Commodore VIC-20 Cartridge PCB 4x16k

This is a multi-game cartridge for the Commodore VIC-20, allowing up to four 16KB games (or eight 8KB files) to be stored in a single module — a total capacity of 64KB.

Main components:

• EPROM 27C512 (DIP28) — requires an external programmer,
• 74LS00 logic chip (NAND gates),
• 2-position DIP switch for selecting the active game,
• Ceramic capacitors and stabilizing resistors,
• Fully through-hole assembly (THT) with optional sockets for chips.

Configuration: The DIP switch selects which 16KB block is active — for single-game versions, switches become unnecessary.
