1. Guys, guys. Why don't you read this first?
http://www.e3b.de/usb/main_mounting_e.htmlThere's no pin 1 on original clockport, that's why there's no marking on Deneb. Original clockport in A1200 starts with pin 20. Nevermind it, just read the above link.
2. I do not expect any problems here, but you need to specify additional paramater to DenebClockport program. DenebClockport can emulate some other Zorro cards with clockport. You can't use emulation of X-Surf if you already have real X-Surf! Try with others that are supported by Delfina. Though I'm not sure how one should specify emulation of other card when using DenebClockport as Flash module...
