I had an HP 7580B plotter on its (non detachable) stand. It was 4ft high and about the same wide, 8 pens and serial / GPIB control. It had auto sheet size detection and manual jogging, as well as the ability to use it as a semi manual scanner to report x-y coordinates back to the comouter. I used it as a vinyl cutter for a bit and it worked ok but never really had the pen pressure... Incredible pen plotter though, so fast and mesmerising to watch. The built in demo was a work of art. It was still working fine when I sold it about 5 years ago, due to complaints from the space police about the appropriateness of such things in a living room, when it was circa 40 years old...
