   Thanks. This is something that I've been wanting to sort out for a long
time. It's been a real battle to find a system with working SW. I had one
that worked briefly but the hard drive in it was rapidly dying and now it
won't boot the HP BASIC OS. However this system seems to be running strong
(knock on wood!)

   Well there really isn't a "standard display" when it comes to the HP
9000 computers. They're all different!

   No I don't. I have virtually no written documentation of any kind on the
Viper cards. However the system that I'm using is a HP Vectra 386/25 with
an early HP VGA card. The HyperViper came in it from HP and it works fine
in that system. I have some other older HP Vectras with 286/8 CPUs that
came with Viper cards. They have video cards with the monochrome/CGA/EGA
type connector. I don't know if the card is monochrome, CGA or EGA. I don't
have any of those monitors so I never bothered to figure out what the cards
were. (I just stick in any old VGA card when I test those systems.) However
I assume that the Viper cards works in one or more of those modes.

  The operating system for the Viper is something called RMB/DOS BASIC so
I'm sure that it's heavily modified for use with the Viper cards.


  BTW there was a HP Viper card on E-bay recently. The auction closed with
no bids. I thought about buying it but it was a B card and I haven't
figured out how to make them work, yet! If you're interested I can give you
the URL and you can contact the seller and see if he still has it.
