So you did, apologies!
I have lots of reading to do, clearly. I have some plans for it. I'm upgrading it with an Ultra 10 case, 1Mb RAM, 60 gig SSD and Solaris 8. I may fit a 440mhz processor card too, because it's got 2mb of L2 cache. Will see how fast it is without, first.
My problem is that, while I used Solaris and OpenDesktop professionally as a software developer, I never did any system admin. Employers didn't tend to hand root passwords to devs back then! So it's new direction for me, and a more intimate relationship with the OS.
It'll be fun...
In the meantime, thanks for your advice.
