Sorry I haven't responded sooner, just got back into town.
Yes the air fixed the problem...and I determined ~60 PSI is the minimum
I will take some pictures of the cabinet tonight when I get home, but the machine has 3 DB9 connectors on the back, one goes to a ~4"x4" board bolted inside the wall (looks like an add-on) and that has a ribbon cable coming off of it (maybe 25 pin, didn't count them) but that is not connected.
The other plate that has 2 DB9 connectors appears to have them wired together (maybe same pinouts) and that ribbon cable runs over to a board in the stack. I am guessing that is the memory board. That board has two DB9 connectors on it as well, but they are not connected (just the ribbon cable). I was not able to see well enough to identify if any of the chips on the board were upgraded. I tried to slide the board up, (after unplugging the edge connector on the bottom) but it appears the slides might lock it in somehow.
This machine appears to have the Parajust (not sure if I have the correct word) retrofit. although I am not sure what that is.
I have attached two pictures, on is the console it came with (but wasn't connected) I am guessing this is not needed with the upgrade to load NC code via DB9.
The other picture is the screen that it started up with.
Also,
I ran through the 'check' 'single cycle' 'operate' buttons and zeroed the table. The machine would run in manual mode. I tried all three axis and turned on the spindle and adjusted the speed. I turned on 'coolant' and the air nozzle started blowing air.
