Can it be run from a PC with MACH3 or other standard software?

The simple answer is that any machine that will accept g-code can be run
"from a PC". Most any competent CAM package could be configured to
output the correct g-codes for it. But the pc doesn't _control_ the
machine, it merely sends the list of machining operations to the
machine's own control. The internal controller on the machine does the
"running" of the lathe.

Mach3 is a control, not a g-code generator, per se. This machine already
has its own control, but the seller doesn't know (or won't say) if it
works.
