Re: [CAD_CAM_EDM_DRO] Group Buy Group Design Group Controller

There was a book "Universal computer interface", by Bruce Chubb.
There he describes how to make modular, expandable interface for the PC.
Consists of a mother board,plugged into PC bus and I/O modules, servo
control modules and so forth.
Can be good for CNC! I believe he has them available at a very reasonable
cost.
