Options:
The void to the right of the two floppy drives can be either open, for convenient storage of a handful of floppy diskettes, or blanked up to conceal one of two options:
Another option is
If either UPS or 8088 options are present the rear or the void is blanked off with a screw-on plate. If the 50-pin 8" disk cable option is present the rear of the void is changed to a clip-on panel securing the 50-pin cable connector.
If no options are fitted the rear of the floppy void is a blank clip-on panel.
If only the 50-pin option is present the floppy void is modified internally with a plastic jacket to prevent stored diskettes from interfering with the rear of the 50-pin header/cable assembly
