I cut one end off a generic yellow-tipped RCA wire and stripped back the insulation. Insider there's one insulated wire (yellow) and one bare copper wire. Which is the positive/negative? Rest assured, I'm experimenting on my own Pi, not the museum's. :) ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)(3) educational non-profit evan@vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation instagram.com/vcfederation
