Write protected. This active-low Schmitt input from the disk drive
indicates that the diskette is write-protected. This input pin needs to
connect a pulled-up 1-KΩ resistor to 5V for Floppy Drive compatibility.
The read-data input signal from the FDD. This input pin needs to
connect a pulled-up 1-KΩ resistor to 5V for Floppy Drive compatibility.
Head selection. This open-rain output determines which disk drive head
is active.

Logic 0 = side 1
Diskette change. This signal is active-low at power-on and whenever
the diskette is removed. This input pin needs to connect a pulled-up
1-KΩ resistor to 5V for Floppy Drive compatibility.
PRINTER MODE:
An active-high input on this pin indicates that the printer is selected.
See the description of the parallel port for the definition of this pin in
ECP and EPP modes.
PRINTER MODE:
An active-high input on this pin indicates that the printer has detected
the end of the paper. See the description of the parallel port for the
definitions of this pin in ECP and EPP modes.
PRINTER MODE:
An active-high input indicates that the printer is not ready to receive
data. See the description of the parallel port for the definitions of this
pin in ECP and EPP modes.
PRINTER MODE: ACK#
An active-low input on this pin indicates that the printer has received
data and is ready to accept more data. See the descriptions of the
parallel port for the definition of this pin in ECP and EPP modes.
PRINTER MODE: ERR#
An active-low input on this pin indicates that the printer has
encountered an error condition. See the description of the parallel port
for the definitions of this pin in ECP and EPP modes.
PRINTER MODE: SLIN#
Output line for detection of printer selection. See the description of the
parallel port for the definitions of this pin in ECP and EPP modes.
