But "WHY?"
Did they leave off the buffer chip BECAUSE the serial card didn't need it?
Or did they use the serial card to cover up a MISTAKE?
Or did they have some OTHER plan for it, and used the serial card as a
"placeholder"?

Tony might know the REAL reason. I have heard various speculations:
for a co-processor card
a mistake
to save 25 cents
because the serial card that was going in there doesn't need it

The IBM Async card can do this (if you put a jumper on the 2 pin header
on the card). A few other cards can too (the Microsoft Bus Mouse card is
one I think).
Yes, the Microsoft Bus Mouse card has a jumper labelled "XT SLOT 8".

Yes it CAN be attached. You'd have to use the GPIO interface and probably have to
write you're own drivers. The GPIO interface is the nearest thing to the original
interface (HP 98034 option 85 IIRC) for the 9885. I THINK I remember that HP did make an
9885 interface for the early 9000 200 series computers but I don't remember the
details. The original interface for the 9885 is a 16 bit parallel interface, it is NOT
SASI or SCSI.

Unless an optional board is installed, the wide Centronics-like connector is
SCSI. It's pretty easy to tell if it's in there, it lives on a set of
standoffs right behind the connector, and the ribbon cable moves from the
mail board to it.
BTW, a 380 can be upgraded to a 385 (33 MHz) with a osc change (socketed!)
and a jumper moved. The '040 in mine has no trouble running at 33MHz, and I

One A1416A board

I don't have a HP catalog any more so I'm not sure what a 98574 is but if

New subject: HP9885 8" floppy unit - resume
Hi again. Well, doing a resume for my own control, and considering
it of interest for everybody, I proceed to send it to the list, with the
permission of the moderator.
We speak about one HP9000/380 with this characteristics:
One A1416A board
One HP 98574 board with... TWO memory chips
Actually, the machine don't have peripherals connected.
I have actually one HP-IB Hard Disk, one HP-IB 5.25 floppy disk,
one HP-IB streamer, and I have the opportunity to acquire one
HP9885 8" floppy disk unit. This last device has couple of back connectors;
one of 50 pin and another one of 37 pin. In appeareance, the HP9000/380
don't have this connectors available. The connector more similar to this
needed
to our purposes, like we shall see later, is one wide centronics connector
with a legend above: "SCSI/ HS HP-IB". I don't have serial terminal,
keyboard, mouse or graphic terminal.
Said this, I have some questions about the machine and its peripherals.
Here we go:
CAN I ATTACH AND USE ONE HP9885 WITH ONE HP9000/380 ?
Joe->
Yes it CAN be attached. You'd have to use the GPIO
interface
and probably have to write you're own drivers. The GPIO interface
is the nearest thing to the original interface (HP 98034 option 85 IIRC)
for the 9885. I THINK I remember that HP did make an 9885 interface
for the early 9000 200 series computers but I don't remember the details.
The original interface for the 9885 is a 16 bit parallel interface,
it is NOT SASI or SCSI.
Tony->
The DD50 is not SCSI (or SASI). It's an HP 16 bit
interface, and was
originally connected to something like a 98032 Opt 085 (GPIO interface
with the right jumpers and cable) in a 9825/9835/9845 machine. I guess it
can be used with other GPIO-like interfaces (but be warned it uses
features of the 98032, like DMA transfers and the register select
outputs, that may not be available on other GPIOs).
The DC37 is the 'raw' drive bus (similar to an
SA800 interface) and is
used to hang 'slave' drives off the controller in this unit.
Joe->
I have several 9885 units. That "SCSI"
connector
is the standard connector that HP uses for GPIO.
CAN BE ONE WIDE CENTRONICS CONNECTOR IN THE BACK
OF THE HP9000/380 WITH THE LEGEND "SCSI/HS HP-IB"
A GPIO PORT ?
Robert->
Unless an optional board is installed, the wide
Centronics-like connector
is
SCSI. It's pretty easy to tell if it's in
there, it lives on a set of
standoffs right behind the connector, and the ribbon cable moves from the
mail board to it.
Joe->
I don't have a 380 any more so I'll tell you
as best as I remember.
If the wide 50 pin port is built into the machine it's probably a serial
port.
A lot of the HP's had those built in. If it's
on a card then it may be
GPIO
but if so it should be clearly marked as much.
SOME INFORMATION ABOUT THE GPIO BOARD FOR THE HP9000
Joe->
[...] But it fits the DIO slot as used on the 9000 200
series and some of
the
300 series. You're 380 has DIO-II slots which are
wider. It MAY have
the adapter that converts the DIO-II to DIO slots but that's something
that you need to check on.
Besides the difference in width, the two cards use different connectors.
The 200 series cards have card edge connectors and the DIO-II cards
have VME type connector. I think some people also call these
Euro connectors.
Joe->
If the port on your machine is GPIO and you are
running HP BASIC
then you don't need anything to manage it except for the binary driver
file.
If you do a LIST BIN. It will tell you all of the
driver files that are
loaded.
I'm guessing that there's a good chance that
you're not running BASIC
on a 380. If you're not, then let me know what you're running and I'll try
to find out if you need a driver and what it's name is.
Let me explain further. If you are running BASIC and
have
the necessary BIN file loaded then you can control the GPIO port
much like you'd control an Intel 8255. You can access it's internal
registers,
set each I/O line as 0 or 1 for logic true, st each as
input, output or
both.
You can also set characteristics for the hand shaking
lines and
interrupts.
But you still won't have any high level DOS type
commands to access
the disk drive (no read, write, save, load commands). I'm not sure
but there MAY be a BIN file that you can load that may give you
those commands. Bt even if you can do that, you'll still need to figure
out
the connectiosn between the GPIO interface and the
9885
HOW CAN I UPGRADE ONE HP9000/380 TO ONE HP9000/385 ?
BTW, a 380 can be upgraded to a 385 (33 MHz) with a
osc change (socketed!)
and a jumper moved. The '040 in mine has no trouble running at 33MHz, and
I
just picked up 16MB of RAM for it (Thanks, Jim!).
HP9000/380 GRAPHIC MONITORS
Robert ->
My 380 has an A1416A Kathmandu (a.k.a. Color VRX)
(1280x1024 @ 60 hz, 8
bits, DIO-II). It has 3 BNC sync on green output, you'll need either an
adapter to a VGA monitor or a monitor with 3 BNC.
Joe ->
There are a whole range of video/graphics options for
the 300 series.
Also on a lot of them you can also use a terminal connected to the serial
port.
One word of caution, you need the correct monitor to
work with the card
that you have.
It's gets tricky trying to find both a monitor and
video card that work
together.
I'm currently using an ADC super VGA monitor that
has both the VGA port
and BNC ports.
IIRC it works with both the 98543 and 98547 video
cards. I have a whole
slew
of HP viedo cards and monitors around but I'm
trying to get away from
having
to have a special monitor for each computer.
WHERE CAN I LOCATE ONE 3 BNC ADAPTER TO A VGA MONITOR ?

PLEASE DON'T YELL. It makes you sound hostile and angry, and most people
consider it quite rude. I will attempt to answer some of these questions,
the ones I can't answer I will ignore.
Said this, I have some questions about the machine and
its peripherals.
Here we go:
CAN BE ONE WIDE CENTRONICS CONNECTOR IN THE BACK
OF THE HP9000/380 WITH THE LEGEND "SCSI/HS HP-IB"
A GPIO PORT ?
The 50-in connector labled SCSI/HS-IB can be either SCSI or HS-IB. Without
an added option board mounted inside the case, it is a SCSI port. With the
card installed and the cable from the connector moved from the planar to the
card it becomes an HS-IP port.
HOW CAN I UPGRADE ONE HP9000/380 TO ONE HP9000/385 ?
Move the jumper labled `P10' from `25' to '33'. The jumper is located
daigonally opposite from pin 1 on the CPU, upper left corner of the CPU as
seen from above with the DIO connectors closest to you. Replace the
socketed 50MHz oscillator `Y2' located to the immediate right of the CPU as
viewed above with a 66MHz oscillator. This will overclock the 25MHz 68040
to 33MHz. It will most likely void your warranty.
WHERE CAN I LOCATE ONE 3 BNC ADAPTER TO A VGA MONITOR
?
http://www.google.com/search?q=BNC%20to%20VGA would be a good place to
start. You can purchase them pre-made, or assemble one yourself if you
like.
WHAT MODEL OF SERIAL TERMINAL CAN I USE WITH ONE
HP9000/380 ?
The default settings are 9600 baud, 8 bits no parity 1 stop bit. Just about
any terminal ever made will work, provided the cables can be mated up and
the console can be switched to the serial port.
When the serial console is enabled, it is merely an extension of the
graphical head. The HP-HIL keyboard remains enabled (and presumably the
framebuffer too), any characters entered on it will be echoed to the console
as if they were entered via the terminal attached to the serial console.
This will allow you to do things like play around on the HP-HIL keyboard and
accidentally switch the console back to the graphical head...
WHERE CAN I FIND ADDITIONAL INFORMATION ?
http://www.netbsd.org/Ports/hp300 is where I found most of my information.
Another place to check would be http://www.google.com/search?q=HP+9000+380.
WHAT IS ONE 34-PIN CONNECTOR IN THE HP 98574 BOARD ?
MAYBE A FLOPPY CONNECTOR ?
I'm not positive, but I believe it is where the HS-IP option board connects
to the planar.

PLEASE DON'T YELL. It makes you sound hostile and angry, and most people
consider it quite rude. I will attempt to answer some of these questions,
the ones I can't answer I will ignore.
Said this, I have some questions about the machine and
its peripherals.
Here we go:
CAN BE ONE WIDE CENTRONICS CONNECTOR IN THE BACK
OF THE HP9000/380 WITH THE LEGEND "SCSI/HS HP-IB"
A GPIO PORT ?
The 50-in connector labled SCSI/HS-IB can be either SCSI or HS-IB. Without
an added option board mounted inside the case, it is a SCSI port. With the
card installed and the cable from the connector moved from the planar to the
card it becomes an HS-IP port.
HOW CAN I UPGRADE ONE HP9000/380 TO ONE HP9000/385 ?
Move the jumper labled `P10' from `25' to '33'. The jumper is located
daigonally opposite from pin 1 on the CPU, upper left corner of the CPU as
seen from above with the DIO connectors closest to you. Replace the
socketed 50MHz oscillator `Y2' located to the immediate right of the CPU as
viewed above with a 66MHz oscillator. This will overclock the 25MHz 68040
to 33MHz. It will most likely void your warranty, and may result in the
magic smoke escaping from the CPU.
WHERE CAN I LOCATE ONE 3 BNC ADAPTER TO A VGA MONITOR
?
http://www.google.com/search?q=BNC%20to%20VGA would be a good place to
start. You can purchase them pre-made, or assemble one yourself if you
like.
WHAT MODEL OF SERIAL TERMINAL CAN I USE WITH ONE
HP9000/380 ?
The default settings are 9600 baud, 8 bits no parity 1 stop bit. Just about
any terminal ever made will work, provided the cables can be mated up and
the console can be switched to the serial port.
When the serial console is enabled, it is merely an extension of the
graphical head. The HP-HIL keyboard remains enabled (and presumably the
framebuffer too), any characters entered on it will be echoed to the console
as if they were entered via the terminal attached to the serial console.
This will allow you to do things like play around on the HP-HIL keyboard and
accidentally switch the console back to the graphical head...
WHERE CAN I FIND ADDITIONAL INFORMATION ?
http://www.netbsd.org/Ports/hp300 is where I found most of my information.
Another place to check would be http://www.google.com/search?q=HP+9000+380.
WHAT IS ONE 34-PIN CONNECTOR IN THE HP 98574 BOARD ?
MAYBE A FLOPPY CONNECTOR ?
I'm not positive, as I don't have one, but I believe it is where the HS-IP
option board connects to the planar.

Hi, Robert !
PLEASE DON'T YELL. It makes you sound hostile and
angry, and most people
consider it quite rude. I will attempt to answer some of these questions,
the ones I can't answer I will ignore.
Ok :-)
I did it for "remark" purposes. Even when I know the netiquette precepts
in this aspect, sometimes I have a sensation of dispersion in these
messages.
The only way I have to divide paragraphs in a correct visual form for me
is to put the head of the paragraphs in CAPS. Sorry if somebody was
offended.
About the rest of the message, it answers some of the questions I have
in a satisfactory way... by the moment, of course :-)
Thanks and Greetings

Hello, Robert:
There are a whole range of video/graphics options for the 300 series. Also on a lot of
them you can also use a terminal connected to the serial port. One word of caution, you
need the correct monitor to work with the card that you have. It's gets tricky trying
to find both a monitor and video card that work together. I'm currently using an ADC
super VGA monitor that has both the VGA port and BNC ports. IIRC it works with both the
98543 and 98547 video cards. I have a whole slew of HP viedo cards and monitors around but
I'm trying to get away from having to have a special monitor for each computer.
I should like to
Unless an optional board is installed, the wide
Centronics-like connector
is
SCSI. It's pretty easy to tell if it's
in there, it lives on a set of
standoffs right behind the connector, and the ribbon cable moves from the
mail board to it.
Mmm.. yes, below the connector appears a legend "SCSI-HP IB".
My doubts come from this.
BTW, a 380 can be upgraded to a 385 (33 MHz) with
a osc change (socketed!)
and a jumper moved. The '040 in mine has no trouble running at 33MHz, and
I
just picked up 16MB of RAM for it (Thanks, Jim!).
Is good to know it :-)
But, being practical, I approach to ask you about another two matters:
* What model of graphic screen can I use with the 380 ? know
about one (or more) model with all its identificacion data to search it in
eBay
or some reseller.
* What model of serial terminal or screen can I use with the 380 to plug
into
the RS-232 port of this computer ? Same than previous.
(Of course I accept all reasonable offer from somebody in Europe. This
includes
one GPIO board)
I'm confused, are you looking for a GPIO card or are you selling one? I can send
you one if you need it. But it fits the DIO slot as used on the 9000 200 series and some
of the 300 series. You're 380 has DIO-II slots which are wider. It MAY have the
adapter that converts the DIO-II to DIO slots but that's something that you need to
check on.
Besides the difference in width, the two cards use different connectors. The 200 series
cards have card edge connectors and the DIO-II cards have VME type connector. I think some
people also call these Euro connectors.

Hi again, Joe:
I don't have a 380 any more so I'll tell you aas best as I remember. If the
wide 50 pin port is built into the machine it's probably a serial port. A lot of the
HP's had those built in. If it's on a card then it may be GPIO but if so it should
be clearly marked as much.
Thanks for the offer but I know what it looks
like. I have several 9885
units. That "SCSI" connector is the standard
connector that HP uses for
GPIO.
Ok :-)
Then it's possible you could give me some additional help. My HP9000 is one
380
model. It comes with one HP-IB standard connector (short centronics) and one
"wide" HP-IB connector of SCSI type. Do you if one of these connectors is
GPIO ? Do I need one additional board to manage GPIO devices
(with independence of
the
specific driver problem you told me in a previous message ?
If the port on your machine is GPIO and you are running HP BASIC then you don't
need anything to manage it except for the binary driver file. If you do a LIST BIN. It
will tell you all of the driver files that are loaded. I'm guessing that there's a
good chance that you're not running BASIC on a 380. If you're not, then let me
know what you're running and I'll try to find out if you need a driver and what
it's name is.
Let me explain further. If you are running BASIC and have the necessary BIN file loaded
then you can control the GPIO port much like you'd control an Intel 8255. You can
access it's internal registers, set each I/O line as 0 or 1 for logic true, st each as
input, output or both. You can also set characteristics for the hand shaking lines and
interrupts. But you still won't have any high level DOS type commands to access the
disk drive (no read, write, save, load commands). I'm not sure but there MAY be a BIN
file that you can load that may give you those commands. Bt even if you can do that,
you'll still need to figure out the connectiosn between the GPIO interface and the
9885.
Can I ask why you're trying to use a 9885? A 9895 has a HP-IB interface and would
be a lot easier to use. And it has a lot higher capacity.

Because I don't have one.
If you know where I can obtain one I should agree to know it :-)
About the GPIO board, I am searching one, my reference to one offer was
an inexact expression. I agree you offer about the board, but my380 has
VME slots and not edge connectors.
Finally, the HP 98574 is the CPU board of the 380. It combines in the same
planar:
* CPU
* HP-HIL connector
* HP-IB connector
* Speaker Connector
* Parallel connector
* SCSI/ HS HP-IB connector
* LAN BNC connector
* LAN AUI connector
... plus the inner mysterious 34-pin connector :-)

Hello. Somebody knows if one HP9885 8" floppy
unit can be attached to one
HP-
9000/380 ? The unit came with one 50-pin SCSI or SASI type connector, and
one
37-pin connector.
The DD50 is not SCSI (or SASI). It's an HP 16 bit interface, and was
originally connected to something like a 98032 Opt 085 (GPIO interface
with the right jumpers and cable) in a 9825/9835/9845 machine. I guess it
can be used with other GPIO-like interfaces (but be warned it uses
features of the 98032, like DMA transfers and the register select
outputs, that may not be available on other GPIOs).
The DC37 is the 'raw' drive bus (similar to an SA800 interface) and is
used to hang 'slave' drives off the controller in this unit.
