PC-1600
2. Block diagram
Since the printer,
cassette,
and floppy
disk drive are all
controlled
by the PC-1600, the CE-1600P and PC·1600F
can not operate by itself.
Battery, however, can be recharged without intervention
of
the PC·1600.
A 32KB ROM within the CE·1600P
contains the program
to operate the printer, cassette, and floppy disk drive.
