EasyFlash

Schematic

Possibly you want to look at the schematic.

Note that the actual cartridge has a slighly different pin assignment, because e.g. logic gates have been swaped to simplify the PCB layout.

The professional PCB

There are many ways to build an EeasyFlash. One is to order the parts from the online shop for8bits.

The First Prototype

Here you can see the first fully working prototype built on a Rademacher PCB Nr. 944 (Conrad 521250). Using a wiring pen or even ordinary magnet wire can be a simple way to get an EasyFlash cartridge. But some patience is required :-) If you want to find a PCB which fits perfectly without the need to cut something, the 8 Bit Baby could be your choice.
