I shipped out one prototype, not heard back how he got on installing it yet though. All the SMD work is done, I just need to sort the rom sockets and pins and there will be some in the store. I am very sorry for the delays.
I have a few built, I am weary of selling them as they need rather complex installation! If you are confident you can attach the jumper wires correctly and have a JiffyDos with a manual switch you can control that too
