Not sure this was posted yet but the Talk RETRO podcast is up, with former RETRO Magazine editor-in-chief Daniel Kayser as a guest. They cover the Coleco Chameleon at around the 53:25 minute mark. Daniel was at the show and claims that was not an SNES, but an actual prototype of the FPGA board in there.
