Hi guys! A small quick project, I did as usual for myself, but I will be glad if it will be useful to someone else. 2 years ago when I was translating the manual for Apple II replica Mike Willegal I found a description of a very complicated way of making these jumpers, but the result is much better. My project is something between soldered wires and the method of the respected Mike Willegal. In the archive there are 2 versions of jumper blocks for 4 and 16kb.
