I've decided to build one of those MIDIBox SID thingys since its documented so good and the modular design makes it a very nice project. I still have some questions that i am unsure and i´d like to be sure, before i start :p 1. Where do i get SID chip(s)? I dont have any old C64's and buying those rare old machines costs a fortune? Is there someone selling SID Chips? 2. What is the difference when you have 1 SID chip and 4 SID chips and how bout 2 and 3? How many should i have? 3. Can i have the Complete Control Surface with only 1 SID chip? 4. Internet site in Germany that sells electronic parts
