you can make system backup using Central control mode "S". There are at least two mode control switches in Main Control Cabinet. One is "overtravel release" and other one, next to "reset" is control mode. Select maintenance mode and your control boots up to maintenance menu. You can re-install from there and you can make a backup copy from there. I'm not sure, if it makes bootable, tihe 1st one floppy.
but first. First You make sure, is the floppy the device for system restore. Paper tape reader could be the one for such an old machine
