This is my first post so lease bare with me. I recently got a 1987 ycm-40 supermax with anilam crusader controls. I'm in the process of cleaning it up which it is in bad shape. I want to use mach 3 and am at a lost with which bob, controller, drivers, vfd to use. As soon as i think i found which components to use, their site is years outdated. Anyone please lead me in the right direction lease? I'm leaning toward huanyung vfd, viper200f, us digital e5 or e6 encoders (if i really need them), still not sure on BOB.
