Hi Montegoman,

yes still using nee software and controller and the security device is still functioning. The machine is now a bit long in the tooth but still working. Programs were all written out by hand - no cam software at the time (at least that I could have afforded then.)
Some of the G codes are different than the latest ones - G81 for instance.
I have noticed that the cam routines generated are quite long to take into account the speed of the latest machines, nothing like the short compact routines I had to come up with because of slow speed of the software inside my skull.
