1.0 INTRODUCTION
The SA4600 Disk Controller is a complete preprogrammed microprocessor based controller
for the Shugart
SA4000 series disk drives and SA800/8S0 Floppy Disk Drive.
The
SA4600 Disk Controller is designed to perform asyncronous
data
transfers between the
SA4000 and a host CPU.
The SA4600 features a general purpose DMA
type
interface designed
to
easily adapt
to
com-
mercially available DMA controller chips.
Several optional configurations also make this interface adaptable to virtually any
type
of
mini or micro computer. Some main features
of
this controller are
as
follows:
A)
Control
of
one
to
four SA4000 drives and one
to
four SA800/8S0 Floppy Disk Drives.
B)
Asyncronous DMA transfer with full sector buffering.
C)
Four
user selectable formats - 32 sectors
of
S12 bytes, 60 sectors
of
2S6 bytes, 104
sectors
of
128 bytes,
or
26 sectors
of
2S6 bytes (Floppy
option
only).
D)
Overlap seek operation (up to four drives).
E) Single five volt supply.

INTERFACE DESCRIPTION (Reference
Figure

The SA4000 drives are interfaced through connectors
Jl,
J2, J3,
J4
and JS.
Jl
is a
SO
pin ribbon cable
type
edge connector which connects the SA4000 drives in a daisy
chain configuration.
Up
to
four drives may be bussed together on this cable. This cable
should
not
exceed 20 feet (6 meters). Refer
to
section
9.l.S
- Cable Termination
Description.
J2 through JS are
20 pin ribbon cable type edge connectors which are the radial connectors
for
up
to four drives.
J2
is
the
radial connector for Drive
1.
J3
is
the radial connector for
Drive
2,
etc. These cables should
not
exceed 20 feet (6 meters). Refer
to
Figure 2 for a
diagram
of
the pinouts for J 1 and J2 through JS.

The status register bit assignment is
5.3.1 Command Busy and Command
When the Host CPU sets a command into the command register,
command busy bits will be set. When the controller reads the command and begins execution, it will reset the command register full bit. During execution, the command busy bit
remains set. The controller will then set interrupt
sequence and reset command busy after the result register has been read. The exception to
this rule is the seek command where command busy

FORMAT DESCRIPTION
As
mentioned
in
the
introduction,
the
SA4600
is capable
of
formatting
four different
formats.
Only
the
three
formats for
the
SA4000
will be discussed.
Each
track
is
divided
up into
data
block
or
sectors. Each
sector
may
contain
128,
256
or
512
Bytes. A full
sector
buffer
is
provided so
that
the
host
interface
may
transfer
data
at a rate
compatible
with its own timing requirements.
Each sector
(Data
Field)
is
preceeded
by
an
identification
field (ID Field). The ID Field
contains
four
Bytes
of
information.
The
first
byte
is
a flag
byte
which
contains
a defective
sector
bit
(LSB)
which
is
set
by
the
host
system
when using
the
