They made trackballs for some of the SUNs. A friend of
mine has one. But I
know that they're hard to find.
I figured it would probably be quicker/cheaper to adapt an existing
trackball than find the genuine article... even if I have to sacrifice a
real sun mouse to do so (ie, just connect the leds/photodiodes in the
trackball to the sun mouse pcb).
Though doing this isn't a priority for me right now. I'll get the system
up first, then decide if a trackball will be worth doing.
Take a look at
<http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3402536373>. If that
looks like the right mouse let me know and I'll send you one for the cost
of postage. Global Priority mail runs about $8 and it will be there in less
than a week.
That's the right one, thanks for the offer. I'll email you off list with
details.
