Molex78802 Module
This is a 3d-printable plastic carrier and matching empty PCB template to fit in the carrier, and both together fit in the option-rom socket in Tandy models 100, 102, 200, & 600. (and any other machine that has that same socket, such as Epson PX-4 & PX-8)

To start a new PCB design based on this PCB template and carrier
- clone the github repo
- copy the PCB directory to a new directory named after the new project
- open the files in the new directory with kicad

Variants
These versions can all be generated from the same OpenSCAD source file.
"chamfer" is the default version
The "bump" version of the carrier can also hold a plain rectangle pcb with no polarity features. It can hold an original REX1, if you are willing to sand the edges of the pcb down a little.
The "max" version maximizes the available usable pcb real-estate on both the top and bottom surfaces. It is not yet tested.
The "pin" version uses a pin and a hole for polarity instead of a chamfer. There is no special advantage to this version over the "chamfer" or "bump" versions.
