Recommendation for Upgrading an Original parallel port KX1 to USB or Ethernet

[JimG]

I'd go UC400ETH. Runs Mach3, Mach4 or UCCNC if you fancied a change.

Or buy a used dell with pport, load XP on it, and away you go. That's what I did for my mill. (but I already had retail discs XP from 2005 so not an issue for me).

I finally went for an ESS installation and that has worked well and it installed with pretty well no problems. I had already gone through the second hand Dell route a few years ago and it was this computer that had given up the ghost. I thought that the supply of old parallel port PCs would probably dry up and thought it was about time I moved on to something that would work with up-to-date PCs.

Jim.
