The people making the A608 are users, not business people they are trying to get them produced but only as their hobby. The PCBs are made, the components on back order and have been for months. Then they need assembling by hand.
Yes and this is why I decided to be very patient regarding the A608, because I realize that it's a hobby project after all. But it would still have been nice to read progress reports every now and then, that was one of the points of the A608 site or what, and now the site seems to be down as well.
While waiting for the A608 to become available, I finally bought a 2MB PCMCIA SRAM card on ebay, and I discovered that my A600 indeed got faster and more useful with it

In addition I have a A603 and 2GB CF card + IDE adapter in my A600 right now.
But I must admit that the ACA630 card sounds more and more tempting.
