Hi all, FOR SALE: 5x 6581s and 2x 8580s I thought I would offer these here, first refusal stylee, before I put them on the 'bay. Prices reflect a combination of what others are selling them for and the amount of time I took to test them. They are all harvested from various C64s I picked up here and there and are all fully functional. I have tested them all using Plogue's SID benchmark program on a real C64 (http://ploguechipsounds.blogspot.com/2010/05/one-page-basic-sid-benchmark
