I've seen this machine and pics before have you asked before.?

Going to be blunt here and say that if you have no experience then your going to struggle with getting this machine going with Mach.
Not saying it won't work with mach it most likely will but not unless you know the machine internals and what pins are what.

It's not as easy as just installing Mach and cable then it works. You need to tell Mach where to send out going signals for motors etc and where to watch for incoming signals E-stop switches etc.
If Mach is sending or looking in the wrong place nothing will work. Even if it is looking in the right place it only takes one wrong setting and it won't work or start.
So first you need to determine what pins on the Machine control what on the machine. Then the cable going to the PC port MUST match this same pin layout. IE: if pin 3 on the machine controls X axis Direction on the drives then pin 3 at the PC port of the cable must match, then in Mach you set X axis dir to pin 3 in motor outputs.
Also in Mach you must provide the PC address of the Port your using and if this is wrong nothing will happen.? So for instance if you are using the Serial port like you mentioned and not the parallel port then chances are Mach by default is looking and sending signals to the wrong place. Thou I suspect you have just called parallel port by wrong name.? But It still highlights how it doesn't take anything more than one little thing and nothing works.!!

Problem you will have with this machine which if your the original person who posted ages ago you where told before is the fact it's an Isel machine and they often used Bespoke hardware and Software combo's so you'll most likely need some modifications to use Mach3 or any PC based control software.?
This is why I say you don't have the experience because if you did then you wouldn't be asking this question again.!! . . . . . . If your not that person then I appologise and just say it's not simple and you'll need to do a lot more research and dig into the machine for the info we will need to be able to help.

Again sorry to be blunt but I'm only trying to stop you going around in circles.!
