512K RAM Board Installation Information
Instructions For HP-Qualified Personnel:
Follow the instructions that apply to the installation you are performing. For example, if you are
installing the RAM card in a 520 computer you would perform the steps that begin with: (ALL), and
(520).

Load Board
Systems that are shipped from the Fort Collins Systems Division with 1 CPU, 1 lOP, and one 512K
Byte RAM Board, will also have a Load Board in the slot that is adjacent to the RAM board (top
occupied slot). If any other Finstrates, or RAM, is added to this configuration, the Load Board must
be removed from the computer.
Any time the Processor Stack configuration is reduced to 1 CPU, 1 lOP, and one 512K Byte RAM
Board, A Load Board (09855-66525) is required. Load Board (09855-66525) is a replaceable
part.

CE Handbook
When completed with the installation, insert this page and the following page in your CE Handbook
(after page 2-12 of either the 9020 or 9030/9040 section).

1 Megabyte RAM Board Installation
Instructions
Read the following information then follow the instructions that apply to the installation you are
performing. For example, if you are installing the RAM Boards in a 520 computer you would
perform all steps that begin with: (ALL), and (520).

RAM Boards
1 Megabyte RAM Boards can only be installed in pairs. Any combination of 256K, 512K, and pairs
of 1 Megabyte boards can be used.

Load Board
If a system is shipped with 1 CPU, 1 lOP, and one 512K RAM Board, it will also have a Load Board
(09855-66525) in the top occupied slot. When the 1 Megabyte RAM Boards are added to the
stack, the Load Board is no longer required and must be removed (assuming the 512K RAM board
remains in the system).

When the only RAM boards in the stack are 1 Megabyte RAM boards, a load board is required if
there are six or less. The load board should be removed when there are more than six 1 Megabyte
RAM boards in the stack, or if there is a mixture of 256K, 512K, and 1 Megabyte RAM boards in the
stack.
Any time the Processor Stack configuration is changed so that it contains one of the above
configurations, a Load Board is required. The load Board (09855-66525) is a replaceable part in
spares. If the load board is used it must be in the top OCCUPIED slot of the Processor Stack. Do
not leave any empty slots between finstates or boards.

Boot Loader ROM
When the Processor Stack contains 1 Megabyte RAM Boards, Boot Loader ROM Rev. B (0902080001) must be used, and UNIX 4.0 or Basic 2.0 software must be used.
Boot Loader ROM 09020-80000 can be used with UNIX 4.0 or Basic 2.0 (or any previous software
versions) as long as the stack DOES NOT contain a 1 Megabyte RAM Board.
Boot Loader ROM Rev. B (09020-80001) can be used with any RAM configuration but MUST use
UNIX 4.0 or BASIC 2.0 software (any earlier versions of software cannot be used with this boot
loader).

Access Times
When the 1 Megabyte RAM Boards are installed in a computer, the access times will be slower. The
customer may notice this slower process time during operation.

System Functional Test
The previous SFT tests (Part Number 09020-10010 Rev. 2.0) are not compatible with the BASIC
2.0 Operating System. The updated version of the SIT must be used with this operating system.
The 4.0 HP-UX Operating System contains the same System Functional Tests (SFT) as the previous HP-UX. They are located in the CE utilities dictionary.

Module Self Tests
Module self tests are contained in the replaceable modules and are initiated on powerup. (The
BASIC language system SCRATCH ALL or LOAD BIN command causes aU module self tests
except the processor stack tests to be executed. No equivalent HP-UX commands exist.) Successful
completion of most tests is indicated by an LED turning on and then off. Because aU modules are
tested qUickly and the LEDs are located in various places on the 9020, you must run the test for
each module you wish to check.

Processor Stack
Each finstrate has its own self test. Results are indicated by twelve LEDs associated with card slots 1
through 12. The LEDs are visible by removing the left cosmetic door and looking through the
window in the stack door. Normal operation is all LEDs on, foUowed one or two seconds later by aU
LEDs off. An LED that won't turn on or that turns on and won't turn off indicates a failure of the
corresponding finstrate.

Processor Stack
Self Test LEOs

Processor Stack Self Test LEOs

Keyboard
This self test turns the CAPS LED on and off and turns the PRINT ALL LED on at powerup. The
BASIC system then turns the PRINT ALL LED off and the CAPS LED back on. The HP-UX
system turns both PRINT ALL and CAPS off.

Printer
An LED on the printer's logic board lights when its module self test detects a failure. The LED is
visible through the air vents under the keyboard.

Disc Drive LED

Printer and Disc Drive LEOs

Internal Flexible Disc Drive/Controller Card
The first part of the self test checks the drive, the drive board, and the controller card. The LED on
the front of the drive indicates successful completion when it turns on.
The second part of the test requires that an initialized disc be stored in the drive. This part of the test
thoroughly checks the drive. If the test passes, the LED on the controller card turns on and off once.
With the right cosmetic door open, the controller card LED is visible through the upper hole in the
110 cover plate.

Internal Fixed Disc Drive/Controller Assembly
An LED on the drive is visible through the air vents under the keyboard. If this LED turns on, the
controller assembly has successfully passed self test.
If the drive LED goes on, indicating the drive is being accessed, but the controller assembly LED
fails to go off, a bad drive is indicated. With the right cosmetic door open, the controller assembly
LED is visible through the middle hole in the 110 cover plate.

Bootstrap Loader Card
The LED on the bootstrap loader card is visible through the middle hole in the I/O cover plate with
the right cosmetic door open. If the LED turns on and then off, the bootstrap loader code has been
properly downloaded to the system RAM. If the LED fails to turn off, the code has not loaded
properly.

Self Test Supervisory Code (STSC)
The STSC runs automatically after the module self tests on powerup. STSC verifies the integrity of
the internal I/O bus, tests the interfaces on all of the internal modules, retests mapped-out memory
blocks that previously failed the memory controller test, and reports the blocks that fail the retest.
The code issues a message to the user in case of a failure.
The modules tested by the STSC are:
• Internal 110 bus

Converging the 9020C Display
l. Run the System Functional Tests using the MAINFRAME TEST PROGRAMS disc. Select the
test for color graphics (CGRAPHICS) then select the CONVERGE option.

2. Open the door located just to the right of the screen (on the display case) to expose 39
alignment locations and the alignment tool; the 39 alignment locations are organized in
rows by adjustment number (13 in all) and in columns by color (red, blue, and green).
Remove the alignment tool from inside the door by pressing its top.
3. A small white plus sign ( + ) is displayed in one area. Additionally, the number 1 appears
along the right hand edge of the display to remind you of the row of alignment locations
you should use to adjust the convergence. Use the alignment tool to merge (if necessary)
the red, blue, and green pluses by turning the appropriate control for the color you are
moving. For example, adjusting the alignment location in row one, column one (the red
column), moves the red plus.
Adjusting the alignment locations causes the pluses to move across the screen according
to the following rules:
a. the red plus moves along a line from lower left to upper right.
b. the blue plus moves along a vertical line.
c. the green plus moves along a line from upper left to lower right.
You may find that the easiest way to merge the pluses is to first merge the red and green
pluses together (forming a yellow plus). Next merge the blue plus (which now lies directly
above or below the yellow plus) into the yellow plus, forming a white plus.

Note
If the character displayed is a white plus with shaded (colored) edges
rather than completely separated pluses, very little adjustment is
needed. Even when the three colored pluses are correctly merged, a
small amount of colored "fringing" may appear around the edges.
This is normal.

4. After you are satisfied with the adjustment for alignment location one, press ~.
Another white plus appears; this is for alignment location 2. Adjust locations 2 through 13
in the same manner as indicated in step 3 above.
5. If you are not satisfied that all pluses are properly merged, steps 3 through 4 may be
repeated as many times as necessary. When you are completely satisfied that the display
is converged, press ~ to exit the routine.

CAUTION
DO NOT OVERLOAD THE POWER SUPPLY BY USING MORE
HP 27123A, HP 27125A, OR HP 50961A INTERFACE CONNECTIONS THAN CAN BE SUPPORTED.

An HP 9020B with a lO-megabyte winchester disc drive must not have more than one of the
following I/O cards installed in it if the MPB and I/O card cages are full. An additional card may be
added for each MPB or I/O slot that is unoccupied. Because these interface cards can power
external devices, they may exceed the per-slot power budget specified by the HP-CIO standard.
Therefore, consider them to take the power of two interface cards. The I/O cards concerned are:
• HP 27123A when powering an HP 98028A SRM MUX.
• HP 27125A LAN/500 Link Interface.
• HP 50961A Option 500 (27123A with SRM Coax Adapter).

To configure the GPIO card:
1. Install jumpers in WI, W2, and W3, according to whether 5-volt or 12-volt logic levels are to
be used.
2. Set the card's switches for proper operation.
3. If necessary, increase the delays on the card as follows:
Two one-shots (EI5) on the GPIO card generate the write delay and the internal handshake
delay. The write delay one-shot provides approximately 100 nsec for the output data to
settle. When extra-long cables are used. or when the peripheral device requires additional
settling time for the data. the delay can be increased by adding a capacitor between pins 1
and 4 of the socket at E16.
The formula for selecting the capacitor value is:
C = (T-I00)/1.5
where
C
T

=
=

additional capacitance (in pf)
total time delay required in nsec

The internal delay one-shot provides a delay of approximately 3 usec between the assertion
of PCNTL and the assertion of FLAG. The delay can be increased by adding a capacitor
between pins 5 and 8 of the socket at E16.
The formula for the value of the capacitor is:
C = (T-3000)/3
where
C = additional capacitance (in pf)
T = total time delay required (in nsec)

When ordering the Loader/lD ROM, the serial number of the computer must be given to the individual taking the order. The serial number is
programmed into the replacement ID ROM. Boot Loader ROM 09020-80001 is required for systems using 1 Megabyte RAM boards and
UNIX 4.0 or BASIC 2.0. The Boot Loader ROM can be used with other RAM configurations if UNIX 4.0 or BASIC 2.0 is used. Boot Loader
ROM 09020-80000 can be used with UNIX 4.0 or BASIC 2.0 (or any previous software) as long as the stack does not contain a 1 Megabyte
board. The above part numbers are replacement part numbers. The ROMs will be labelled 1818-3467 (Rev. A) or 1818-3461 (Rev. B).

Keycap Part Numbers
The last four digits of the keycap part number are provided for each keycap. The first four digits are
always 0371. For example. the "J" keycap is identified on the ASCII keyboard as 2632. To order
the "J" keycap. order part number 0371-2632.
All keycap configurations except ASCII have some keycaps highlighted. The highlighted keycaps
differ from the keycaps on the ASCII keyboard. The ASCII keyboard is the exchange assembly in
case of keyboard failure. Before returning a failed non-ASCII keyboard, remove all non-ASCII
keycaps from the failed board and place them on the replacement keyboard .
