From the project
Systems-matching the requirements of novel-ideal in metal to architecture
A project to build a system that uses my concept of novel metal to architect a new kind of computer system. This repo serves as a single point-of-reference containing hardware (in PCB form) and software. Multiplicity is the theme.
I adored my 6809 machine - A Tandy Color Computer CoCo 2 - it took a significant amount of effort to obtain one. I had asked my parents one Christmas in 1981 but the $399 price tag was too much - considering I had just asked them a few months prior to help me purchase a used Hewlett-Packard 5036A Microprocessor Training Kit where I could learn the ins-and-outs of…
