http://www.amiga.org/forums/showthread.php?t=64691&page=3Now have an Amiga GOTEK running nicely thankyou very much. Time to buy another.
Happy to provide any tips for anyone thinking of doing it. I'm not a great solderer and had 2 pairs of reading glasses on when I was soldering on the jumper pins. Some people have just used wires but I was worried I'd screw something up.
It was a challenge finding the time but fun and certainly not hard to do.
Picture of GOTEK and Soldered pins attached.
Cheers
