Hi all

I have been tasked with programming a 1995 Busellato Optima 55 CNC router.
I have worked on similar machines on days gone by but have never programmed this particular one.
Does anyone have or know of any information to get me started?it's an ancient DOS based setup!
I'm sure with a bit of know how I will be away!
Any help will be greatly appreciated.
Thanks in advance.
