content: Anyone got a busted C64/C128? Or any SID chips you're not using?I really want to build either a MIDIBox SID or something similar, and the prices for SID chips on eBay is crazy! If you've got some you don't want, I can probably offer you something.Let me know!

content: You may well be able to get a whole C64 cheaper than an individual SID, keep an eye on this one:http://www.ebay.ca/itm/Commodore-64-complete-working-system-C64-extras-disk-drive-keyboard-joystick-/161090836623

content: C64s, original and C64C are common as dirt, don't spend good money on eBay, can prolly get one out of a garbage bin or garage sale.The C128 on the other hand, you'll be hard pressed to find anyone who'll part with theirs ;-)

content: They are much cheaper in Europe, where the C64 was most successful. I bought a C64C a while ago for less than 3 euro on eBay.

content: Is it just the SID chip your are interested in?I have a few yamaha synth chips they used on arcade games back in the 80s.I could spare you one of these when I get to my spares in a couple of weeks.

content: I have a few of the sound chips from the sega genesis and Ti-99http://en.wikipedia.org/wiki/Texas_Instruments_SN76489They are really easy to control, just feed them a 4MHz clock and throw bytes at it. I could spare one if someone was going to do something cool with it.Hmm... combined sn76489 and SID synth?

content: Why a real SID? You can download a free VST, like this:http://delamanchavst.wordpress.com/2013/10/21/minisid/And then you have as many SIDs as you want.But what do you think of a MIDI interface for the C64? Currently I'm developing one:http://www.frankbuss.de/c64/midi/index.htmlWith such an interface you could use a SID inside a C64, leaving the C64 fully working. I could try to write a VST and the backend on the C64 to control it. Or maybe there is already a documented interface and a VST to control a SID over MIDI?You can even use the C64 to create music

content: There are a few different variations of SID chips used throughout the production of the C64, I'll crack mine open in the garage to see what's in there come to think of it.
