Parport schematic...?

["P.K. Ferrick" <ferrick-at-telenet.net>]

Hi all,

Sorry to repeat this question, but it seems as though it might have
gotten
lost in the NAMES shuffle...!

I've come across a really nice CNC tutorial that I don't recall seeing
any mention of on the list or in the faq, so I thought I'd post a link
here.

Most importantly, it has a really nice schematic of a parallel port
interface that includes 4 axes and ganged limit / home switches.  Maybe
somebody could take a look and comment on the usefulness of this circuit

to EMC?

thanks,
Pat
