Hello to one and all

Have joined this group to see if I can get advice on upgrading my software to modern standards.
At moment I run Supercam on 3 milling machines and Flashcut on my two lathes
I use an old version of AutoSketch for some drawings and produce other drawings with Supercam its self
Unfortunately all my software will only run on win95 and win98
Old computer systems are getting harder to find so I will have to bight the bullet and find a new software setup to replace my old obsolete systems
Any advice would be appreciated on which drawing system and cam system to use .
Thanks in advance from an old cnc dinosaur.
