Just an update about availability.
Since a few weeks there is a large interest in FPGA boards for BTC mining. (More than ever, Obviously a matter of BTC price). Because I'm not willing to produce these FPGA Boards on my full own risk anymore they are only produced upon request now. Estimated lead time is 8-12 weeks. A fraction of the production costs have to be paid in advance, before the parts are ordered. Details can be found at

Production of one 1.15y batch has been started last week. It can't be increased anymore. Another one will probably start by end of next week and can be increased within a few weeks. That means I also can accept 10 and 20 unit packs until mid of May (or until the capacity limit has reached.)
