Does someone already have a KiCAD footprint for the card edge, or a drawing so I can create one?

Since the Apple II connector is being used, I would imagine that there are probably some footprints out there, as expansion cards for the Apple II are still being made, albeit at 'boutique' scale...

I'm hoping that I'll be able to develop some hardware cards for the CX16, mainly as a hoist prototype board. I see +12,-12 and +3.3 V on the connector, but no + 5V one. I assume that a simple 7805 regulator on the board will be retro and support all the old 5V retro logic chips that I have.

I know there are much better regulators out there but the old 7805s are what I have in my parts bin.

VCC is +5V.

Thanks - missed thinking about VCC when I looked at the connector.

I may be wrong, but I think there's still no public information about any PCB because there's still nothing final and things can change. So, creating any piece of hardware for the platform at the moment is not possible.

Now that some comments have brought this up toward the top of the queue, I'll note that I believe that @Kevin Williams has mentioned that they've shifted to a slot with some more pins.

It's not yet documented with the above level of detail, but they are busy working on getting key parts of the system working well, so as always, patience is in order.

I small question. Where is the CPU Clock pin or does this even have a clock signal at all? I have a board being designed right now and it requires the CPU's clock signal.
