The Maximite Computer

The Maximite Computer is a small and versatile computer running a full featured BASIC interpreter with 128K of working memory

It will work with a standard VGA monitor and PC compatible keyboard and because the Maximite has its own built in SD memory card and BASIC language you need nothing more to start writing and running BASIC programs.

The Maximite also has also 20 input/output lines which can be independently configured as analog inputs, digital inputs or digital outputs.  You can measure voltage, frequencies, detect switch closure, etc and respond by turning on lights, closing relays, etc – all under control of your BASIC program.

The design is free and open source including the software and BASIC interpreter.   And all this is powered by a single chip which costs just US$8.44.

The Maximite was described in the March, April and May 2011 issues of Silicon Chip magazine.  This web page is intended to provide support for people who have built the Maximite and are looking for new firmware, corrections to the articles, etc.
