Some of you recall my plea for assistance a couple of weeks ago under the
subject "RGB-to-VGA adapter & docs was: Re: HP "Field Guide" ?"
:
Upon the date 19:55 24-03-05, Christian R. Fandt said something like:
I lack a correct monitor for the fixed frequency output
of the RGB card.
The card is a 98547A which has three BNC connectors;
--snip--
Since the purchase, I've been trying to find a way
to view the RGB output
on a typical VGA monitor that would sync to the output.
--snip--
Well, I think I just got lucky. I stopped by the local Salvation Army
thrift store just to check if any interesting odds 'n' ends showed up.
There was something.
There stood an NEC 5FGP (model JC1741UMA) 17" monitor. It had five BNC
inputs (w/sync on green, it was marked), plus the mini 15 pin VGA
connector, plus the standard size D-shell 15 pin connector for MACs. I
grabbed it.
I think I hit the jackpot. Has every input I might need to check out most
vintage hardware except CGA/mono stuff.
But there's one problem which explains the $3 price as monitors are usually
$5-$15 in that store. The display is very dim. I can see an image okay with
the room lights off.
After dark.
With no full moon (:-\
I found a 5FGP tech manual online in .pdf. I feel I can turn up the
red/green/blue gun drives and bring the intensity up to a somewhat useable
level. Done it before successfully with several color televisions and an
old CGA monitor. Also, the specs indicate it should sync up well to the
fixed freq video output from my HP 9000/375. Yippee!
All is not lost. After all, this thing won't be used daily, only for
testing and messing around with the HP 9000/375. I feel good now. Just
gotta find some danged time and table space to play with all the stuff.
Which brings me to the next important question . . . maybe Joe R., among a
few others, could provide input:
Upon initial bootup there may be HP-UX of some version found running on it.
It may need a password. How would I get around it, if possible, and set my
own?
It has that Series 300 DOS Coprocessor, 98286A, which I presume either runs
under HP-UX as a task or independently directly under DOS 3.x. That is if
indeed the 7958B HDD was not wiped during demil before the military
surplused the system. I have no idea what to expect as I'd never booted the
thing before. Any HP-UX "features" I should know about before getting too
far into running it? I do have a doc set for HP-UX 5.5.
Thanks in advance for your help.
Regards,
Chris F.
