Ah yep I see it on your image. Don't know how I missed that :roll:

Looks like IDE connectors have a missing pin...

Though as they in packs of 20 I'll just pull a couple pins out assuming the missing pin has a hole for it..

Some headers do have a missing pin for keying purposes, but some don't. I think it's better to use a "plain" header with all the 40 pins.

If you don't find the headers with all the pins at Ebay, just buy them at Mouser or Digikey. I know they will be more expensive, but we don't need much and I'd gladly pay a bit more for high quality headers. Or if you prefer I can order them myself and make them ship to you direclty.

If my other PCB stuff doesn't fail this time, this board might actually get produced soon. Probably take a couple weeks before I get it. Then will have to solder the headers on etc.

Looks fantastic. Do you want me to order to headers, or you will? Thanks a lot.

it looks cool,
I wonder whether it could be used as PiSTorm relocator for motherboards where the CPU is under the keyboard.

Its a custom pinout so doubt it.

There is this relocator for the 70789 already https://www.exxosforum.co.uk/atari/store2/#0237
