TOPIC Hardware

[photo of TOPIC hardware]

TOPIC is a combined programmer/project board for the 16x84. The photo shows my prototype and this is slightly different from the final version; you can probably see that the PCB pattern was drawn by hand. The TOPIC schematic shows the simplicity of the hardware but it can be further simplified if all you want to do is program a 16C84 (a brief description of the necessary changes is included with the documentation).
