Hey First I think you people all rock for doing those great machines by yourself and for sharing all the experiences. I'm not an expert and my knowldege for electronic circuits is more or less equal to zero.Soldering should not be a big problem since I'm quite familiar though with it.Since the documentation on the site is so good, I understand most of the processes but there are few things I am confused with.My initial goal is to just control 1 Sid for the beginning and later on upgrade it to the 4 Sid variation.So far I don't see any touble later to upgrade the CS since it is also very nicely documented on the site (the pics are just great !)I got already the 6581 Chip from an old C64 so I am about to start assembling parts.Before ordering I wanted to know the following things: 1.How to connect Midi to the CORE Module? (is an LTC Module needed for it or do you connect a midi socket directly to the Midi Port of the core) 2.The power supply Which parts from the original C64 board do you need and is there smth. like an assembly guide for it? ;D(or pics) 3.How to connect the AUDIO out? If I don't mistake it goes straight out from the SID Module, but then you just conect it to mono female jack or are ther some more parts involved in it that you have to assemble yourself? That's it basically.I would have posted another question but I couldn't figure out how to put a picture (yes, my html sucks too :-[) So if somebody can give me a hint for that I would be thankful so i could update the post later on regarding that question. Thanks to you all for the help, I'm excited to get started.
