Solaris

Hello,
I'll already apologize for my question, as it'll probably be hurting for an expert.
About two years ago I obtained a used Sun Ultra 10 with many accessoires for a very low price. I'm not much into UNIX (or rather not into it at all), but I wanted to play around a bit with it, especially as it is equipped with a SunPCI-coprocessor-card. Worked fine.
Unfortunately due to low free time, the Sun Ultra 10 caught much dust. Today I powered on this thing again and everything worked, except of the mouse. I also tried booting from a Solaris 7 CD - mouse also doesn't react there. So is it safe to assume it's broken, or might I have made a wrong setting somehow? Unfortunately I cannot test via obdiag - keeps telling me about an external loopback device required or something like that. I just know it worked before. But it's possible the mouse was hit by a license plate falling of the fall once (I have some as decoration)

If it's broken - what should be the price of a used Type 6 mouse in your opinion?

Thanks in advance and sorry again for this question. Have a nice weekend!

It could be broken and I really can't think of any good way to test it. They usually run about €20-€30 used on ebay ( quoted in euro since you appear to be in europe ) , but you might be lucky and someone here might have a spare they are willing to donate.

Try check with any of your friends.. maybe they can get you for free from somwhere in their office

My friends most likely don't even know what a Sun Workstation is. Okay, I also wouldn't claim, that I knew, but at least I own one and also learned how to manually boot it

Well, I guess I have to wait some time (not that it would matter much). Considering I bought the whole box including Keyboard, Mouse, Tower, Coprocessor-Card and so on for about 80 or 90 EUR spending 20 EUR for a lousy mouse really is a no go
