5.5.5. Connector X801 (Floppy)
All signals are TTL compatible.
DR0#
Drive select 0.
INDEX#
This active low Schmitt Trigger input signal senses from the disk drive that the head is positioned over the
beginning of a track, as marked by an index hole.
TRK0#
This active low Schmitt Trigger input signal senses from the disk drive that the head is positioned over the
outermost track.
WRTPRT#
This active-low Schmitt Trigger input signal senses from the disk drive that a disk is write-protected.
RDATA#
The active-low, raw data read signal from the disk is connected here. Each falling edge represents a flux
transition of the encoded data.
DSKCHG
This disk interface input indicates when the disk drive door has been opened. This active-low signal is
read from bit D7 of location base+7.
MTR0#
This active-low output selects motor drives 0.
HDSEL#
This active low output determines which disk drive head is active. Low = Head 0, high (open) = Head 1.
FDIR#
This active low output determines the direction of the head movement (low = step-in, high = step-out).
STEP#
This active low output signal produces a pulse at a software-programmable rate to move the head during
a seek operation.
WDATA#
This active low output is a write-precompensated serial data to be written onto the selected disk drive.
Each falling edge causes a flux change on the media.
WGATE#
This active-low, high-drive output enables the write circuitry of the selected disk drive.
