Georg never did a large production run, nor did he ever sell his boards in quantities.
The boards he designs are made Public domain, the groupbuy for 100€ was initiated by someone else then Georg.
@Buzzfuzz:
It's not a normal A1000, as you can see it already has the hugely expanded GB1000 mainboard, which already incorporates an 68030/688882 at 50Mhz.
The exciting thing on this turboboard however is the fact that it only connects to the 68030 socket, that means it might be adaptable to fit other machines apart from the GB1000....
