I have a Leadwell from the late '80s. I've ask FANUC in US, they do not have the sheet with options for my controller. Since Leadwell TW doesn't have the build sheets for older machines, the only source I have is old manuals. There is one guy in TW that allegedly has the old build sheets, but he never replied to my emails.

My personal opinion, anyone using '80s cnc controllers should be supported and sponsored (from mfgs' mkting budget) as a testament to the controllers' durability.
