Hi jon.
The ver 94.1 p4-3 is the highest software level compatible with the 1400-3 and 1400-4 cpu.
The -3 runs a whopping 8086 processor while the -4 is running a 80286 dx 40 if I recall.
The main difference from an operator standpoint is the -3 does not support a graphics card, according to a recent conversation I had with Neal at Fadal.
If you attempt to use the graphics function, nothing happens (as there is no card)---This is a pretty good tip off that you do not have a -4 cpu.
BTW: All the manuals are available from Fadal online as .PDF files, it is a no brainer that if you dont have one you should endeaver to print one off as it can be quite helpful untill you become more aquainted with the quirks of operating the controller keyboard functions.
I had close to 20 years experience on various controls when we bought our first Fadal and frankly, I was clueless even after exploring the keyboard for a couple of days. So I spent some time actually reading the manuals. For instance, pressing the manual key repeatedly toggles the controller between the command prompt and the mdi mode, this can be quite confusing at first. Add this to the fact that repeapely punching the space key makes various other menus appear and, well, you obviously understand what I am getting at.
So if you keep punching buttons and still seem to be clueless as to how the controller operator interface actually works, hopefully reading the manuals should help some.
Good luck,
