FUNCTION
PRINTER MODE: ACK#
An active low input on this pin indicates that the printer has
received data and is ready to accept more data. Refer to the
description of the parallel port for the definition of this pin in ECP
and EPP mode.
EXTENSION FDD MODE: DSB2#
This pin is for the Extension FDD B; its functions is the same as
the DSB# pin of FDC.
EXTENSION 2FDD MODE: DSB2#
This pin is for Extension FDD A and B; its function is the same as
the DSB# pin of FDC.
PRINTER MODE: PD7
