Replaced TD4B PCB

A project log for TD4 CPU

TD4 CPU is a "4bit CPU that runs". It is very interesting for what can be done with so little.

Replaced TD4B PCB

Well not much choice, EasyEDA corrupted the PCB after an upgrade (gone wrong again?).

Anyway, this version does not have the RAM add attached or the page register:

The PCB is public so if you want you can get your own version of the PCB (x5) from EasyEDA.

It is fuctionally the same as the last one I built, just redrawing the PCB. It is quite a neat CPU (but very limited). Certainly a good choice for a transistor or relay conversion.
