What is it?

OpenC64Cart16K is an Open Hardware Cartridge for the Commodore 64. It only supports 16 KB ROMs and uses a single (E)EPROM chip. It is the 16 KB counterpart to OpenC64Cart.

Why did you make it?

OpenC64Cart16K is designed to accept a 64 KB (512 Kilobit) (E)EPROM with a 27512-style pinout.

Such chips can hold up to 4 cartridge images, which can be selected by jumpers.

The recommended part is Winbond W27C512 (or W27E512, I don't understand what differences they have), which is widely available, cheap and electrically erasable, which avoids the need for a clunky UV-eraser. This is the only part that was thoroughly tested. Other parts, even smaller in size, will probably work, but will require an ad-hoc configuration.

Usage is straightforward: just insert the EEPROM in the socket making sure that the notch and all pins are aligned, set the jumpers as desired and plug the cartridge in your C64.

What makes it special?
