My shop is in the basement of a old fruit warehouse. there are 14 shops in it and most of us are woodworkers. for soem reason a couple of the guys I cut parts out for want to get a cnc router. so they buy a older model of this puppy. theirs uses the even bigger then 5.25" floppies.

the all the controller is in it's on box that is refrigerated.
they want to use their own controller on it build their own. I can somewhat see it but I don't know if they will ever get it done.

but the cool thing is how easy this sucker moves. you can push the gantry with 1 finger and very little effort. smooth as silk. thats what impressed me the most. it would be cool to see it run but who knows.
