J14 (Optional Floppy Disk Interface Connector)
J14 is a surface mount connector location for a 26-pin optional floppy disk (located on
the solder-side of the board). This interface is provided primarily for single board
computer operation (without an STD 32 backplane. STD 32 users should use the
ZT 8954 Floppy Disk Controller Interface for floppy support).
The pin assignments are shown in the "J14 Optional Floppy Disk Interface Connector
Pinout" table below. See Chapter 18, "
Optional Local Floppy Disk Interface
" for more
information.
