Latest Pendant design with wiring diagram W/Keyboard Emulator

I've been working for a number of weeks on the concept of using a
terminal emulator (such as the IPAC-4 or the Hagstom KE-72 among
many others) to eliminate much of the control wiring which we are
used to stringing around our machines. My tool is a Brideport 2J to
give a sense of scale, but the concept will work on both larger and
smaller tools. The design is with MACH2 in mind, but should be
pretty generic as the control is hardware multiplexed based.

OK, actually got the chance to put the wiring diagram on paper.
I've posted it along with my latest idea for a control pendant. By
using a keyboard emulator, my diagram went from something that
looked like a bowl of spagetti thrown against the wall to a svelt
almost blank piece of paper.

I'm not sure what the Spindle-Auto is connected to (my diagram was
wrong, so I'll have to physicaly check it out).

If anyone has any suggestions, please be brually honest as I'm
getting close to tearing out my current control wireing (working :-)
and putting this stuff in place.

Whoever said "if it aint broke don't fix it"?
