Excuse the name, I don't really want to call this a replica, partly in respect to Vince's great efforts, and partly to avoid confusion. If you have a better idea, let me know.
I have all the hard to find parts on hand and am working on the finishing touches of the PCB. Take a look at these pages to what I have going on and please provide any constructive feedback or ideas before I commit to fabbing an initial batch of PCBs.

Thanks for your feedback and interest.
PS I have been helping an obtronix board owner investigate an difficult to bring up board. As part of this investigation, we have discovered a possibly missing trace on one, of his two Obtronix boards. The board with the missing trace was purchased as a bare board. The board that is not missing that trace was purchased as a kit and is working fine. This trace also appears missing on the scan that Vince posted, a while back. If you are having trouble bringing up or have had success with your Obtronix board, I would be interested to discuss this with you.
