9000/827s console (mux) pinout?

Hi all,

I kinda got a 9000/827s dropped in my lap a couple of days ago, and since then I've been browsing this forum to fins a soloution on how to connect a console to it... I didn't find anything that really helped.

The thing is that I didn't get the MDP panel, nor the cable to it. What I really, really, really would like to know is:
- The pinout for the mux connector.
- Is the 5062-3074 cable a console cable, and if so, what's the pinout for it?

I can't say that I'm very familiar with HP stuff, but I have an old 9000/715/50 that I kind of like....

Btw, ist the 827 just as prickly about what cdrom it likes as the 715/50? *grin*

Hi
Can you tell the pins details (no of pins male/female ) for both console and console

Hi
Can you give me the pin details (no of pins Male/Female) for the console and server

The server has the large 70+ pins female connector, and the terminal has the standard 9 pin female serial interface.

Would be reallly nice to get the thingy running and doing some work... :)

It's not a pinout problem. The MDP panel has electronics inside so without the panel, the box is just a boat anchor. The 827 would only be useful if you can get a free or almost free MDP. And yes, to boot these VERY old systems, the boot ROMs require that the CDROM be strapped to the correct sector size.

Re: 9000/827s console (mux) pinout?

Okay, thanks. I'll try to get the MDP panel but I'm pretty sure it has been tossed out already, as it is some time since the machine was taken out of service.
So, probably I have a good boat anchor... :)

If I dont get the MDP I'll just rip out the useful things, like fastethernet cards, disks and DAT tapedevice, and throw the rest into the bin...

I'll stay on here though, as I like to pick up knowledge, and that is a thing that you can't ever get enough of. :)

Re: 9000/827s console (mux) pinout?

The 827 is 100% proprietary as far as the cards in the backplane. Nothing compatible with a PC or even with newer HP computers. The tape drive is likely a DDS-1, SCSI-2 SE and the CDROM (if there is one) is either 1x or perhaps 4x speed. Note that the 827 (and other models like 817, 837, 847, etc) also came in an HP-IB version where the disks were not SCSI but HP-IB. HP-IB is an instrumentation bus (IEEE-488) but HP designed disks, tape drives, even printers to use HP-IB. It was the USB of the 80's but could not easily be enhanced so no further work was done with peripherals and HP-IB. The HP-IB connector looks like a smaller (but mechanically stronger) Centronics connector. These devices are museum pieces today although many are still in service...and running very old, non-Y2K software.

Disks are scsi, at least the external ones, so they are useable on some of the other old hw I have around. :)
Otherwise it sounds like a real boat anchor...

Btw, what are the specs on the 827s? Is there a link to some technical documentation anywhere?

Start with the HP Museum...

Seriously, this machine predates your 715 workstation and was obsolete long before HP web pages were used for such documentation. A search through hp.com didn't find anything relevant, and Google provided just a couple of entries: http://docs.rinet.ru/UNIXi/ch29.htm and http://hwdb.parisc-linux.org/view.php3?type=machine&name=827%2F48

The CPU is a PA-RISC chip PA-7000 and part of a family called Nova that was first sold in the late 80's. Back then, the product numbers were fairly sane (807, 817, 827, 837, 847, etc). Later, these were all changed so that uname -m was confusing (F,G,H,I) so your 9000/827 was also called an H20. The I/O was known as NIO (Nova I/O) to differentiate it from the previous generation of CIO boxes such as the 825, 835, 845, etc. Processor speed is probably 48Mhz, RAM is completely proprietary.

Re: 9000/827s console (mux) pinout?

I have one of these machines too.
Best resources can be found at
http://www.openpa.net/systems/nova.html
You don't need to use the MUX port as the Novas have a PS/2 style serial port.
(Adapter can be homemade by use of an obsolete keyboard cord.)
Mine was an F10/807 upgraded to F30 using the CPU of a G30/847.
Drop me a message, if you need some memory.
But is there any expert reading this who knows how to set up an E25/806 which has a mux port only?

Re: 9000/827s console (mux) pinout?

Sorry about the MUX-only response. Indeede, the entire Nova class (8x7 and F,G,H,I series boxes) use the mini-DIN console cable. I have an H60 (aka, an 887) plus an E35 and it's the E35 that uses a MUX panel only. Here's the pinout for the cable:

You can clip off the cable from a busted PC keyboard and create the above console cable. Also check out the reference table at: http://www.openpa.net/systems800.html for more specs on the old models.

Re: 9000/827s console (mux) pinout?

Thanks for some excellent replies!
I browsed the links and found a lot of good stuff, but then I found that my machine doesn't really fit the descriptions...
The label on the back says model 827s, and thus it should be a H20. But a H20 has only 4 HPPB slots, whereas mine has 6...
There is no mini-DIN connector, so I guess the I/O board has been "upgraded" at some time.

Anyhow, I've sent off a mail asking if the MDP is still available. If not, I'll send it off to the happy huntinggrounds in HP heaven... :)

A good bookmark for HP parts is partsurfer.hp.com and yes, a MUX panel is available (it's called an ADP-II) for only $270 US, probably 3x more than the 827s is worth. The core I/O board came in a couple of flavors, thus the difference you are seeing (no mini-DIN console).

Note that at the OpenPA website, the features of the various models are shown including pictures and detailed descriptions. You might be able to find a different core I/O board that has a mini-DIN connector) but if you can locate the MUX panel, make sure it has a cable to the computer too. Also note that you may need a crossover cable for the console rather than a straight-thru. The best choice (for unknown hardware) is to have a crossover adapter.

Re: 9000/827s console (mux) pinout?

Yeah, buying a panel isn't really an option. The only reason to even try to get it up and running is out of curiosity. The 827 definately has a place among my old Sun-3's and Diab's.
I kinda have my own little museum in the basement...

I'll know in a couple of days if the panel and cable still exist, so I'll just have to be patient. Thanks anyway for all the info, I've learned a lot so far, and it's not over yet...

Re: 9000/827s console (mux) pinout?

P,

This may help you if you are still interested in getting your old clunker to work.

I recently aquired a E25 server, and got a 700/96 HP console to work with it. (I even got a FLT 707D message on the console! yipee!)

I used a J2094-60004 cable connected to the MUX port on the server. the J2094-60004 has two 9-pin connections. the one labeled "MDP 0" should be connected to a 5062-3054 MDP. The console needs to connect to port 0 on this panel.

Re: 9000/827s console (mux) pinout?

Josh, the problem is that I don't have the MDP panel at all. Probably it has gotten thrown away in the process to take the 827 out of service. I have asked at the site if they can find it, but haven't had any answers yet...
I'll give it another week and then I'll scrap the machine.
Too bad, but that's life...
