The Maximite 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.“
„My Z80 microcomputer is hand wired using the wire-wrap prototyping technique. This method uses thin 30 gauge wire, a special wire-wrap tool, and wire-wrap sockets. The sockets have 1/2 inch long square posts, which you use the tool to wrap (or twist) the wire onto the post. As long as you have 5 or more wraps on the post for a single wire, the connection is semi-perminant. This method was used because it’s easy to change connections and is faster than soldering each wire. Wire-wrapping was a popular method used in building early computers. In fact, the AGC computer used for the NASA Apollo missions were completely wire-wrapped! After I finished my computer, I went through more than 350 feet of wire!“
