Diode PROM

Here is the Diode PROM:

The "CS" DIL switch allows up to 8 PROM cards. I am only using one this time.

The board layout is as follows:

Laying out the diode PROM is quite time consuming, and near the limits of the Easy EDA auto-router. So I will add the CPU design to the diode PROM schematic and PCB design.
