For a long time looking for documentation and drivers for this model.
I understand that without a service plan i will not get the drivers. But there is documentation available somewhere?
I'm really desperate - pre-installed Solaris 10 (03/05) works great. but I'd like to know more about this nice hardware and try to install a newer system(the problem is WLAN and VGA)
Does anyone have experience with Ultra3 and can help me?
There never was much documentation, and I suspect you'll not find any of it still floating around any more.
The Sun Ultra3 laptop was a system manufactured by Tadpole Systems.
They just stuck the Sun name onto the outside of its case.
The Ultra3 was in the Sun Microsystems product line for only a short time, then was quickly discontinued. Very few were sold.
Tadpole Systems has since become a part of General Dynamics:

You could also use your favorite web search engine for such terms as "Sun Ultra3" or "SPARC laptop" or the like.
Since it wasn't truly a Sun product, Oracle isn't going to have much of anything related to it.
Indeed, even the Internet archive does not contain much information on this topic.
I am surprised that there are no data on oracle.com about hardware who has not reached the end of the "Premier Support Ends."
Unfortunately this is not the equipment produced by Tadpole. It's a completely different product produced by Naturetch. There were four models of the "Sun Ultra 3":
A60-UltraSPARC IIi (Tadpole SPARCLE)
CPU: 550 or 650 MHz UltraSPARC IIi
