I have a couple of HP flat bed plotters (7220 style). At least one of them doesn't work (drastic fuse-blowing problem, probably aged power supply capacitors).
I saw one on ebay, advertised at a silly collector price - is this just wishful thinking on the part of the seller or are these something rare that I should preserve ?
I could hack them up to use for building things (pcb handling stuff) but this is something I wouldn't do for calculators. Should I recycle old plotters ?
