Wow, well this is a really weird damn problem then if it's not
the baud rate. It does work fine for minutes at a time. Most of
the bad is when you first turn it on. I have now, over the past 2
days checked putting in a different keyboard and cable and
optical mouse. No improvement.  Any other ideas anyone?
der Mouse?

Actually something bad just happened.:((( oh but you have
to laugh:))) my SS2 just blew up!  Just then! I'm currently
suffocating in the smell of burning electronic components.
It looks like the power supply blew up. Wow. BAck to the
drawing board for the sparc I reckon....

HEY I wonder if the power supply was on the way out
(I had a couple of strange un requested reboots in the
last 2 weeks), and if the rail voltage was down perhaps
the mouse couldn't function optimally?


cheers,
Paul.
