This is a collection of pinouts and basic descriptions for all of the various chips used in NerdConsole.
There are several different types of chips used in NerdConsole.

This 32KB RAM chip is used for NerdConsole's 16KB of Main RAM. There aren't any readily available 16KB static RAM chips, so the decision was made to use a 32KB chip instead, and only use half of it.  Main RAM was intentionally placed on a separate chip from Extended RAM to simplify bank selecting logic.

There are several different types of chips used in NerdConsole.

Processor

RAM
