Thanks for the heads-up, TomKeddie and southerngentuk. As time is at a premium for me just now, I'm going to hold off on drafting a formal group buy agreement until I get some insight into the viability of creating new PCBs for the generation 2 chips. It doesn't sound like it'd take much alteration, but I could be wrong.
There are no bids yet for this product.
Unsurprisingly there doesn't seem to be a huge demand for these chips. There isn't much point to an auction when the starting price is the price you expect for something. Will be more interesting if these come back onto the market at bargain prices.
