Hi. I'm using ProCad+ on a Kenetic RiscPC. I can plot drawings using Plotter+ to a HP Designjet 500 plotter using the parallel port. I need to upgrade this computer to an Iyonix machine soon, using ProCad+ 106b and Plotter+ 1.06b which offers a USB option in the settings menu. Does anyone use these applications on an Iyonix and if so does the USB option work.
