I have the software and manuals, all you need is a DMC-1020 (2 axis) Galil card.
These are legacy cards due to them being ISA bus, but for these applications they are more than powerful enough.
I have got them off ebay for as little as $50.00 each.
I have several program examples, back-gauges etc, using the OPINT software.
It is extremely easy to use and screens can be set up in minutes once you gain a little proficiency.
Steppers do not use encoder/scale feedback, I would defiantly look at servo's if using a scale etc.
You can also use a scale with a proportional valve controlled by Galil.
The DMC-1000 manual can be had off the Galil site and you also just need to learn the Galil two letter commands.
