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->

> 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 _at_ 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 ?
John->
> I had this problem a while back, and wired up my own
> cable. The simplest solution yet found (suggested on
> this list) is to combine an HD15male/BNC cable and a
> HD15female/HD15female gender changer. A cable like
> this in a single piece I have not yet found.
> BTW, anybody know the signals on _HD26_ video
WHAT MODEL OF SERIAL TERMINAL CAN I USE WITH ONE
HP9000/380 ?
Robert->
> Any null-modem cable to a peasea set to 9600,8N1 should work. Note,
> however, that the serial console (vs the graphics head/HIL keyboard) is
> selected by a firmware command. The commands can be entered blindly
> without a monitor attached, but a HP-HIL keyboard *MUST* be used
> if it is not set to a serial console already.
WHAT'S ABOUT ONE HP-IB TERMINAL ?
Joe->
> I've never heard of one. Does anyone make one?
> I'm pretty sure all of HP's are RS-232.
WHERE CAN I FIND ADDITIONAL INFORMATION ?
Robert->
> You can find some more info on the page for the hp300 port of NetBSD,
> http://www.netbsd.org/Ports/hp300, and Jim Conrad may have some parts
> avaliable, you can find his original post in the classiccmp archives,
> http://www.classiccmp.org.
WHAT IS ONE 34-PIN CONNECTOR IN THE HP 98574 BOARD ?
MAYBE A FLOPPY CONNECTOR ?
Joe ->
> I don't have a HP catalog any more so I'm not sure what a 98574 is
> but if it's a video card then the connector is probably for a daughter
board
> with more video RAM. That's pretty common on the HPs. I DOUBT
> that it's for a floppy drive even if it's not on the video card.
WHAT'S ABOUT ONE EIGHT DIP-SWITCHES BANK IN THE
A1416A BOARD ?
No answer yet :-)
