This active low high current driver issues a low
pulse for each track-to-track movement of the
head.
This input senses that the drive door is open
or that the diskette has possibly been changed
since the last drive selection. This input is
inverted and read via bit 7 of I/O address
3F7H.
Active low open drain outputs select drives 0-
1.
These active low open drain outputs select
motor drives 0-1.
Indicates the drive and media selected. Refer
to configuration registers CR03, CR0B, CR1F.
This active low Schmitt Trigger input senses
from the disk drive that a disk is write
protected. Any write command is ignored.
This active low Schmitt Trigger input senses
from the disk drive that the head is positioned
over the outermost track.
This active low Schmitt Trigger input senses
from the disk drive that the head is positioned
over the beginning of a track, as marked by an
index hole.
Indicates the drive and media selected. Refer
to configuration registers CR03, CR0B, CR1F.
Receiver serial data input for port 2. IR
Receive Data
Transmit serial data output for port 2. IR
