This PC was several years old when I bought it reconditioned in 2010 for my CNC setup. It has worked reliably ever since running mainly Mach 3 under Win XP, driving a lathe and mill through the parallel port. It will come with its external power supply, mouse, keyboard, VGA cable and adapter, plus 3 25-way cables and a changeover switch box. There is also a "Shuttle Express" which can be used for jogging. The PC has Mach 3 installed though it may need some reconfiguration to revert to using the parallel port. I will delete the Mach 3 licence (transferred to my new machine). It has a few other useful but free apps such as Libre Office and G-Simple. This is FREE to a good home provided the buyer collects from near Cambridge - or will rendezvous to hand over within 20 miles of Cambridge.
