Help with Post Processor

Hi everyone, I am looking for help in acquiring a post processor to use on Alphacam advanced mill to allow me to run in DNC full 3 axis mode.
My original post was written in 1998 by a company called Cyncro Ltd who no longer exist.
Without this I don't think I can run full 3 axis so any help very much appreciated. I have the DNC dongle to allow the use as 3 axis but without a processor I'm stumped.
The machine is a Prototrak 2000 with an MX3e controller by South Western Industries. Original machine supplied by XYZ Machines Ltd

Does anyone on here either write posts or can point me to someone who can help me out?

cheers
