@cpfuture:
I bought the same equipment about a year ago with the same result - it doesnt work. I have fitted the Silver Surfer on clockport 0 in "the only way which it can fit without modifying the A500 case".
Also tried all available drivers to no avail.
Tried the Silver Surfer in an A1200 where it worked, so it doesn't seem like I have attached it the wrong way in the A500.
I actually also emailed Jens, asking if the Silver Surfer is supposed to work with the A500 clockport adapter, but never got a reply.
Found the stuff laying around today and googled to see if someone else had this issue and found this old thread.
Would be glad if someone could confirm wether or not it is supposed to work in the A500 with this clockport adapter.
