Replacing old NUM 750 to EMC2

Replacing old NUM 750 to EMC2 was created by brunosas
I'm looking to change a NUM750 to EMC2
The machine itself, has
-132 inputs (almost all used)
-132 outputs (also almost all used)
-2 analog inputs for feed and override
-6 analog outputs for the axis (XYZ, UWD)
It has 4 spindles, which are controlled by one inverter: UNI2403, assisted with a analog input to 4-20mA card I think
The axis drives are Digitax DB220.
I think without loop back? Is that possible?
I'm now wondering whether I could change to a system with EMC2, and, if so, which hardware should I use, are those drives compatible etc...
Thanks for your comments already!

Can you explain more of the actual machine? maybe a picture too.
Sounds like you are gonna want to look at Mesa cards if you rally need that much I/O.
I will let Peter advise you on the best route there.

I think you might manage that with 2x Pico PPMC systems:
www.pico-systems.com/motion.html
For about $2260 (2 x motherboard, 2x DAC boards, 2x quadrature counters and 12x IO cards gives 96 SSR outputs and 192 inputs)
This would be your best option if you wanted to interface through the parallel port.
Alternatively Mesa (www.mesanet.com) make various systems based around PCI-mounted FPGA cards. I think that your machine could run from a 5i25 PCI card with 1 x 7i77 on header 1 and then a 7i74 + 2x7i70 + 2x7i71 on header 2 (you would need a second DB25 header adapter for the 5i25).
That gives 6 servo analogue outputs (-10 to +10V) 6 encoder interfaces and 128x 5-32V inputs with 112x 5-32v output drivers. (You can more than double that IO with extra cards, there are 5 card connections unused in that configuration)
That comes to $713 (or $662 if you can use 5x7i69 TTL input cards, ie if the logic is 5V not 12 or 24V).
The output cards mentioned above have 300mA (7i71) or 25mA(7i69) drive capability. If you need 48V and 2.5A per channel then you would be looking at 5 x 7i64 cards for a total cost of $1109, (as you hit the volume break point of the 7i64 cards) for 156inputs and 136 outputs including the ones on the 7i77 card.
I think all the cards have a few low-resolution analogue inputs, though those are normally handled by quadrature counters in EMC2 applications. You might want to consider a 7i73 pendant controller ($49) to add 4 x jogwheel inputs and some digital inputs for keypads etc.
You would need to check these configs with Pico or Mesa, I have no connection to either company.

The machine is an Emmegi Quadra (older type)
I've uploaded some small pictures of the machine.
It's a machine to for cutting/milling/driling on Alu frames for windows.
So you've a conveyer on each side, and in the center the actual machine.

I think it would be possible to control one with EMC2, you might end up with a lot of M-codes to perform cycles.

This is indeed the newer type of the machine.
But it also has 6 axis, and 4 spindles (but only 1 inverter, spindles are relay controlled)
