Passive one-to-three Commodore 64 user-port expander with an onboard reset button.

The Arcadia by Eye-Box listing was out of stock on 2026-07-27. A reviewed Shareware Plus unit exposed three connectors. The right-hand position can obstruct the cassette port, and the passive board has no per-slot disable controls. Connect or remove peripherals only with power off.

Three-slot C64 and C128 cartridge-port expander with per-slot switching, a fuse, status LEDs, and reset.

AMI64 presented a current-priced listing on 2026-07-27. The seller explicitly excludes the Commodore 64 Ultimate and Ultimate 64. Cartridge combinations can still conflict electrically or in the memory map, so change connections only with power off and enable only known-compatible combinations.
