Instructions:

This zip file contains two further zip files with the gerber files for the program and character PCBs. You can upload them directly to a PCB manufacturer of your choice, I used https://jlcpcb.com/ , but anyone should work really.

The program board will have 4 layers (a ground and power plane in the centre) and the character board will have 2 layers.

Settings:
- PCB thickness: 1.6mm 
- Surface finish: ENIG (this is a chemical gold plating process)
- Gold Fingers: Yes (this adds a process for gold plating slot connectors)
- 30 degree chamfer: Yes (This adds a bevel to the slot connector)
- with jlcpcb you can set "remove order number" to "specify location", which should move the production code under one of the EPROMs.

The remaining settings can be left as a default. I selected a red solder mask to make the pcbs make stand out, but any colour works. Colours other than green cost extra.

If you're curious, this is more info than what you'll ever want about manufacturing options:
