Bill Of Materials
Once you get the Development Cartridge (ShadowRAM) PCB, it's time to gather all the necessary components. Make sure you pick up all the component for a particular configuration; some components differs due to the chose options and the desired configuration.
Note
Assume all ICs are in DIP package, resistors are rated 1/4 W and capacitors 10 V or higher, unless noted otherwise.
