Hi new member requesting some advice please

Hi I am new here and just getting started with CNC machines, I have acquired a Boxford A3 HSRi from my work.
Everything works off the front panel as it should the only issue is that I don’t have the computer with the software to use the machine in auto mode.
I have read on here and the internet that the Boxford software isn’t very good and at a cost of £614 + vat for a single use license this doesn’t seem worth it.
I have read about people modifying / upgrading this machine to bring it in to the 21st centur and make it work better.
So I’m just after some advice on what steps to take or what parts people recommend to upgrade this machine please.

Cheers Tom
