To make one you need:

May 2022 Update - this is now release 2. Apart from correcting swapped keys that existed in revision 1 (see below) I made a lot of traces simpler. I used KiCAD 6 for this, it just keeps getting better. If you build a revision 2 I would love to hear about it.
Revision 1 Errata: Many people have built it and never noticed. That goes for me too - one person contacted me and said they were having trouble with some music tracker software because it relies on the keys that are not in the right place. I had not noticed because I had not been using software that relied on those keys - sorry if you were affected! The revision 1 PCB should be modified:
The PCB has been revised to revision 2 (the same as Commodore's schematic) now so this is fixed, but if you have a revision 1 and notice the ' and , appear to be swapped then you may need to apply this change.
