Re: [CAD_CAM_EDM_DRO] Stupid Newbie Tricks

At the local state surplus agency there are a couple of racks of IBM tape
drives, probably a dozen or so, that they want $100.00 for. I was thinking
about buying them for the servo motors, but I was unsure as to what kind of
motors were in them. Can't remember the model numbers of the drives right
now but they are large cartridge type drives, not the reel to reel type.
Anyone know if these are worth going after?
