I've got a C-128D and a C-64C, both in mickey mouse condition, and working 100%, but I don't think I could ever bring myself to part with them. Plus I've got roughly a 1000 or so disks chocker-block with C-64/128 software. To be honest though, I can't remember the last time I fired either of them up, cool, now I have something to do Sunday :-D
