No
PIN ASSIGMENT(by: sort)
DESCRIPTION
1
STB#/DS0#_D14/_P14/_D12:O An active low pulse on this output is used to strobe the
printer data into the printer. The STROBE output is the
complement of bit 0 of the printer control register. Refer
to parallel port description for use
of this pin in ECP and EPP mode. Active low outputs
select driver 0.
2
PD0/INDEX3#_P14/_S:IO/I
Port data 0.
This active low Schmidt trigger input senses from the
disk drive that the head is positioned over the beginning
of a track as marked by an index hole.
3
PD1/TRK0#_P14/_S:IO/I
Port data 1
This active low Schmidt trigger input senses from the
disk drive that the head is positioned over the outermost
track.
4
PD2/WRTPRT#_P14/_S:IO/I
Port data 2
This active low Schmidt trigger input senses from the
disk drive that a disk is write protected. Any write
command is ignored.
5
PD3/RDATA#_P14/_S:IO/I
Port data 3
Raw serial bit stream from the disk drive, low active.
Each falling edge represents a flux transition of the
encoded data.
6
PD4/DSKCHG_P14/_S:IO/I
Port data 4
This input senses that the driver door is open or that the
diskette has possibly been changed since the last drive
selection.

PD6/MTR0#_P14/_D12:IO/O
Port data 6
This active low outputs select motor Drives 0.
9
PD7_P14:IO
Port data 7
10 ACK#/DS1#_T_D12:I/O
A low active output from the printer indicating that it has
received the data and is ready to accept new data. Bit 6
of the printer status register reads the ACK# input. Refer
to parallel port description for use of this pin in ECP and
EPP mode.
11 BUSY/MRT1#_T/_D12:_I/O
This is a status output from the printer, a high indicating
that the printer is not ready to receive new data. Bit 7 of
the printer status register is the complement of the
BUSY input. Refer to parallel port
Description for use of this pin in ECP and EPP mode.
This active low outputs select motor Drives 1.
12 PE/WDATA#_T/_D12:I/O
Another status output from the printer, a high indicating
that printer is out of paper. Bit 5 of the printer status
register reads the PE input. Refer to parallel port
description for use of this pin in ECP and
EPP mode. This active low high current driver
Provide the encoded data to the disk drive. Each falling
edge cause a flux transfer on the media.
13 SLCT/WGATE#_T/_D12:I/O
This high active output from the printer indicates that it
has power on. Bit 4 of the printer status register read the
SLCT input. Refer to parallel port description
For use of this pin in ECP and EPP mode.
This active low high current driver allows current to flow
through the write head.
It becomes active just prior to writing to the diskette.
14
AFD#/DSB#_D14,_P14/_D12:O
,O/O
This output goes low to cause the printer to
automatically feed one line after each line is printed.
The AFD# output is the complement of bit 1 of the
printer control register. Refer to parallel pot description
for use of this pin in ECP and EPP mode.
15 ERR#/HDSEL_T/D12:I/O
A low on this input from the printer indicates that there is
a error condition at the printer. Bit 3 of the printer status
register reads the ERR# input. Refer to
Parallel port description for use of this pin in ECP and
EPP mode. This high current output selects the floppy
Disk side for reading or writing. A logic “1” on this pin
means side 0 will be accessed while a logic “0” means
side 1 will be accessed.
16
INIT#/DIR#_D14,_P14/D12:O,O
/O
This output is bit 2 of the printer control register. This is
used to initiate the printer when low. Refer to parallel
port description for use of this pin in ECP and EPP
mode. This high current low active output determines
the direction of the head movement. A logic “1” on this
pin means outward motion, while a logic “0” means
inward motion.
17
SLIN#/STEP#_D14,_P14/_D12:
O,O/O
This active low output selects the printer. This is the
complement of bit 3 of the printer control register. Refer
to parallel port description for use of this pin in
ECP and EPP mode. This active low high current driver
issues a low pulse for each track to track movement of
the head.
