SERIES 90, PM9005 OPERATING INSTRUCTIONS
(2704/2708 PERSONALITY MODULE)
2704 and 2708 PROMSs require a specialized programming sequence. This sequence causes
the
PM9005
personality module
to
operate in a manner different than other personality modules.
The programming characteristics
of
the 2704 and 2708 PROMs require
that
when any location is
to
be
programmed, all other locations
must
be programmed
to
prevent data loss. It is important
to
note
that
if
data is
to
be added
to
a partially programmed 2704 or 2708 the
existing
data
must
be
reprogrammed when
the new data
is
added.
MULTI-PASS PROGRAMMING
The programming technique for the 2704
or
2708 specifies a fixed
number
of
passes through all addresses
to
guarantee programming
of
worse-case devices. Using the
multi-pass
technique the Series
90
performs
100 programming passes through all addresses. This operation requires
just
over 2 minutes
for
a 2708.
The required multi-pass programming is accomplished in PM9005 personality module by buffering all
data in a RAM memory. The relationship
of
the RAM memory
to
the
COPY ROM and
input
devices
is
shown below.

PROM-RAM TRANSFER
The RAM
buffer
collcts
the data
to
be programmed
into
the PROM. When the RAM buffer is full the data is
automatically transferred
to
the PROM by the multi-pass programming technique. The LAST ADDRESS
location
of
the RAM buffer is used as a signal to start the
multi-pass
programming.
LAST ADDRESS condition occurs when data
is
entered
into
the last address location
of
the RAM. THE
LAST ADDRESS is defined as either:
LAST ADDRESS
for
2708
is 3FF
LAST ADDRESS
for
2704
is1
FF
THE LAST ADDRESS must be programmed in order
to
transfer data from RAM
to
copy PROM.
1
MANUAL OPERATION
LIST and VERIFY modes are not affected by the multi-pass programming requirement.
In
LIST, data is
listed direct from the
COpy
ROM.
In
VERIFY the COPY ROM is verified against the MASTER
ROM
or
other input device data.
PROGRAM and DUPLICATE operate as described in the operating procedure except that data from
the
Input device (Keyboard, MASTER s-ocket, Paper Tape, TTY) is collected in a RAM memory until the LAST
ADDRESS
condition
occurs. When the LAST ADDRESS is detected the Series
90
begins the required
multi-pass programming sequence, transferring data from the RAM
to
the
2708/04.
As the programming operation proceeds in either the PROGRAM
or
DUPLICATE mode the Hexadecimal
display
will
indicate the pass count in decimal from
00
to
99. At the end
of
pass
99
a read pass compares
the RAM and PROM. If any address does not compare the read pass halts and displays the address and
RAM data in the hexadecimal display, and the PROM data in the binary indicators. The read-check
operation
will
continue
with
the ENTER key.
When the read-check, operation is complete an
"F"
will
appear in the
display
indicating the operation is
finished. -
SPECIAL OPERATIONS
The RAM memory has special operating characteristics which may
be
useful
for
editing
or
adding
to
a
partially programmed PROM. The cO'ntents
of
the PROM in the
COpy
socket are automatically transferred
into
the RAM when the
first
data character is entered in either PROGRAM
or
DUPUCATE. Data can also
be
entered to the RAM from any
ofttje
input
devices (Keyboard, MASTER socket, Paper Tape, TTY, etc.).
If the ADDRESS FIELD
definition
does not include
the
LAST ADDRESS the
inpufoperation
will
result in
only
filling
the specific field of the RAM. Data can be entered
to
the RAM in segments from more than one
input
device.
It is important
to
note that the RESET key causes the entire
COpy
PROM contents
to
be
transferred
to
the
RAM. If
multiple
modes (PROG and
DUP)
are used
to
enter segments
of
data
to
the
RAM the RESET key
should be used only at the sta'rt
to
condition
the RAM. Thereafter
until
the operation
is
complete, mode
changes should
be
made
without
using the RESET key.
When the RAM is
full,
or when
it
is desired
to
initiate
programming, the
PROG
mode can be
used
to
enter
the LAST ADDRESS. When the LAST ADDRESS is entered the programming operation
will
transfer the
complete contents
of
the RAM
to
the PROM using
the
100 pass programming
technique~
,
OPERATIONAL
~DELA
YS
Because
of
the size
of
the 2704
(512
addresses) or 2708(1024 addresses) there will' be some notable
pauses as the Series
90
performs certain operations.
1. Erase check preceeding any operation requires 3 seconds
if
the PROM is
fully
erased.
2. Transferring the contents
of
the PROM
to
RAM which automatically occurs when
the
first
data character is entered in the PROGRAM
or
DUPLICATE modes requires
three seconds.

OPERATION WITH SERIES
90
OPTIONS
All Series 90
options
are designed
to
work
unbuffered operating
on
one
location
at a
time.
Since
the
PM9005 requires buffered operation
to
do
the
multi-pass
programming
it
operates
with
the Series 90
options
in a
different
manner than the unbuffered personality
modules.
3
Operation
With
The
9101
Paper Tape Reader
Option
The
9101
VERI
FY
paper tape
function
operates
normally.
The
9101
DUPLICATE paper tape
function
proceeds
normally
but data is collected in RAM
buffer
instead
of
programming.
If
the LAST ADDRESS is
included in the address field, control is transferred
to
the PM9005 personality module. The operation
proceeds as defined
for
manual operation. Control is not regained by the paper tape.
If the LAST ADDRESS
condition
does not
occur
the
data remains in the RAM
buffer
and programming
does not occur.
Operation
With
9102 Teletype Option
The LIST and VERIFY
teletype-functions
operate normally.
The PROGRAM and DUPLICATE teletype
functions
proceed normally
but
data is collected in the RAM
buffer. If the LAST ADDRESS
condition
occurs, control is transferred
to
the PM9005 personality module.
The programming operation proceeds as defined
for
the manual operation. Control is
not
regained by the
teletype. If programming errors occurthe error
information
appears in the Hex
display
as in the keyboard
operation.
If the LAST ADDRESS
condition
does
not
occur
the data remains in the RAM and programming does
not
occur.
Operation
With
9104 Parallel Interface
Option
The 9104 LIST mode operates normally
with
the PM9005.
The 9104 PROGRAM mode proceeds normally
but
data is collected in the RAM instead
of
programming.
If
the LAST ADDRESS is included in the address
field,
control
is transferred
to
the PM9005 personality
module
when the last address data transfer occurs. The RESPONSE
for
the last data transfer
will
be
delayed
until
the mUlti-pass programming is
complete
as defined below.
The programming operation proceeds as in the manual operation. When the programming and read-check
operations are complete,
control
returns
to
the 9104 remote
option.
Sucessful programming is indicated
by a normal RESPONSE signal. Unsuccessful programming is indicated by
the
RESPONSE-ERROR
signal
combination.
If programming is unsuccessful
it
is
necessary
to
LIST and compare
to
determine
Which
locations
failed
to
program.
If
the
LAST ADDRESS
condition
does not
occur
the data remains in the RAM
buffer
and programming
does not occur.
Operation
With
9105 RS232 Option
The 9105 LIST
mode
operates normally
with
the PM9005.
The 9105 PROGRAM mode proceeds normally
but
data is collected in the RAM instead
of
programming.
If
the LAST ADDRESS is included in the address
field,
control
automatically
transfers
to
the PM9005
personality
module
when the last address data transfer occurs. The acknowledgement
for
the last data
transfer
will
be delayed
until
the
multi-pass
programming is complete as defined below.
The programming operation poceeds as in the manual operation. When the programming and read-check
operations are complete,
control
returns
to
the 9105 remote
option.
Successful programming is indicated
by a normal ACK
control
character. Unsuccessful programming is indicated by the
NAK
control
character. If programming is unsuccessful
it
is necessary
to
LIST and compare
to
determine
which
locations
failed
to
program.
If the LAST ADDRESS
condition
does not
occur
the data remains in the RAM
buffer
and programming
does not occur.
