Here are the pc components ready to be fitted into the enclosure which also houses the operator interface. I made the decision to put them here instead of the other enclosure which houses the electrical components which drive the machine. I hope this will allow me to interface the operator interface directly to the computer hardware, avoiding any unwanted electromagnetic interference.

I have a piece of abs to mount the components but I may change this to aluminium plate at some point as this plate will also be a rear mounting plate for the keyboard. Next I need to find a suitable flexible conduit or something simalar to connect the operator interface to the drive control enclosure. I will need it to run a 12v power supply to the screen and computer hardware. It will also be used for the parallel cable which connects the Mesa 7i76 breakout board to the 5i25 fpga card. I still need to decide wether to use a separate breakout board for the control interface or wether to run all of the buttons mpg and feed/spindle override knobs back to the 7i76 in the other enclosure.
I’d be grateful for advice on this.
