Memory Device Base Size
Sections 2 and 3 of SW1 indicate the base memory device size. 64K is the only
presently acceptable option. Sections 2 and 3 are both positioned to the left; any
other combinations are reserved.
Monitor Line Length
Sections 4 and 5 of SW1 define the monitor line length, in characters, when the
computer is turned on. Position these sections to the desired configuration for
either 40- or 80-character line length.

Set these sections to the positions which reflect your floppy drive complement.
