I find it a little hard to believe that anyone would try to build a band-saw controller on a Windows box in the way suggested by the post and assumed by so many of the comments.<p>It seems likely that the Windows PC is just a job manager and GUI for a simpler embedded controller that actually controls the band-saw. A standard PC doesn't have, as standard equipment, any I/O capabilities suitable for machine control, after all. When I did software for industrial controls, most of the controls that had PC interfaces were built that way; an embedded controller in the machine, running a real-time OS, actually actuated all the relays and optos and was responsible for all the safety interlocks. The PC would talk to that controller through a serial port and put a pretty face on the front of things. If the PC crashed, the operator wouldn't be able to run the machine, but the machine wouldn't go berserk.<p>I understand why someone would say that running a browser on the Win 3.1 machine is a bad idea, but it may not really be that bad.
