Maybe you can educate me, I haven't been in there in a while. I beleive that my X-surf only has A1200-style clock ports on it. In my E-mails with Jens, he never mentioned another method to interface the Delfina to my system. He did have me remove a few resistors on the back of the Delfina. This made no difference. I also tried a half dozen versions of Delfina.library. In the end, he admitted that the drivers were not finished. I got the impression that he designed the hardware and someone else was supposed to deliver the software. In truth, I was sold a half-finished and untested product. ("...There is nothing we can't improve.." sour grin)
This is how it was left a few years ago. Has anything changed?
For what its worth, I've had no problems with the X-surf.
