From the project
Collection of homebrew P2000T cartridges
A SLOT1 cartridge designed to enable selection from 32 memory banks, assuming the use of a 512KB ROM chip. It features a dedicated bracket PCB for holding the DIP switch, which can be connected to the main PCB using either six wires or a custom flex cable. Additionally, this cartridge includes a soft reset switch, equipped with a debouncing circuit using a 74HC123 multivibrator. This cartridge uses THT components.
