Re: Syntax for Bridgeport Boss 6 canned cycle?

Unless my memory has gone south, when I used to program these things
over 20 years ago, they had a few canned cycles including pocket
milling, bolt circle and maybe others...

...and yes I believe that they did in fact have polar coordinates.
The control that I was programming was a Boss 5. I'm amazed that
this old machine that I purchase for my garage still has most
everything still operational...

Does anyone here in this Group have an old Bridgeport CNC
Programming Manual?
