I know that this is the card one uses when doing CAD on this machine because it's capable to show wireframes in real-time.

I didn't mention this before. A message was written to the screen telling us that the card needs the res./freq. you mentioned above.

They tell you how to open/close a machine, how to do this and that but i don't remember that they gave me that much information like you do - in none of their fool-proof docs :) [please don't flame me, just wondering why most of the docs ommit the real needed info's - in many systems - and: i like Sun and their machines] > If you have a recent Sun monitor and nothing in > the NVRAM, it should work. > For now i do only have access to a few mostly high-end multisync monitors (17"-21") which all (even the 17") meet the needed res./freq. But i can get a real Sun monitor in a few days. Fortunately i have access to one - if (and this is the funny part) i am able to show that the card is working properly - so the weird thing is - i must establish this with a non Sun monitor. Should i say that financial reasons raise such situations :( > A few thoughts: Sun framebuffers generally don't do sync on green, so > if you are using 13W3->coax converter make sure it has 4 BNCs.

We tried a SGI monitor with cable and the screen gave me the impression of a mixture between distortions produced with different syncs and another kind of distortion that went into color. So i'm quite sure the green sync lock was what i saw in addition to the different freq. syncs. And i suspected sometimes the connection to be wrong. But as i expected, those 'specialists' (a few 'friends of a friend of a friend of...') didn't know as much as what was stated in the sparse docs :) The connectors are what i may have to resolder a bit - to make it cheap and fast. > Another idea might be > to forcibly set resolution and refresh rate (though not all framebuffers > support more than one rate).

So i hope the Gfx card will do what it's made for - then the Sun will be my terminal and the SMP-PC will be the background server (and more). If there may be no way to get the card up and running fine (what i don't expect), i'll have to put in some RAM and then the Sun will be the background server. BTW i'll try do do a more minimalistic debian install on the Sun, so i hope i won't hit too many bugs (and at least i don't expect to be hit that hard - i trust Debian:) > >32MB RAM is not much.

You gave me more than enough hints and valuable info - so i'm quite confident to be able to come back to the list tomorrow (oh, today, hehe) with a sum of positive steps (which i hopefully may accomplish today). In any way, today i'll come back. Either with news or more specific info and questions ;) Ah, where do i get the pin-specs for the std RGB connector of the card? I tried Sun's homepage but didn't find anything. BTW i have to cables. One is std RGB connector <--> std VGA monitor connector and the other is std RGB connector <--> std RGB connector (which is probably useless for me) My monitors supply std VGA monitor connectors and 5BNC (RGB and HV sync). Another cable with 5BNC connector <--> std VGA connector is here, too. So i have to buy another cable and/or an adapter - or to solder it myself.
