It lets you add on such peripherals as digital to analog and analog to digital converters. All address and data lines are buffered in order to provide extended drive capabilities. All address lines are decoded for ease of operation and all internal and external memory is inhibited when you select I/O. A rear edge connector allows you to use other add-ons such as a printer or a RAM pack at the same time. You can add other [Microdevelopment](http://localhost/company/micro-developments/) peripherals to this board (a “BeeperClock” Module or a D/A — A/O converter) or you may custom build your own addons.
