When the machine is plugged in, I have power but no control manually-cannot run the spindle, cannot use the jog keys to move the axes etc.....a few lights are coming on alright. I have since found out that the machine was bought in 1986/1987 and ran on the old 5inch floppys. Computer has long since been thrown out, and all documents and floppys too!

Thanks for the advice guys I'll go with this much and see first! Much appreciated! :)
