The only reason this product was never released must have been it would have required too much of Jens' Time to put into production.
Either there was a design fault with the original card that needed to be fixed, the production was particularly difficult, the accompanying software was never finished or something... (Perhaps he held off sale because he felt it might steal sales from Clone-A?)
I reserved mine right at the start of the project back in 2002 and was told by Jens that he had pre-orders for the first 200 and more.
Profit and demand were not deciding factors I believe.
