hi folks!

hi to everyone!
i'm a newbie to the list. i'm 27yo, i come from italy and i work in a dot.com 
developing open source financial software with linux os.
i'm about buying an old sparcstation 20 with two sm61-2 cpus (60mhz, 2mb 
cache), 128 (or 256) mb ram, 2x 2gb hard disk.
currently, i'm told the machine runs solaris 8... obviously, i'd like it to 
be tux-powered.
it's the first sun i'm dealing with, and my current background is only the 
linux-sparc howto... so, take pity on me plz!
i'd like to have some good advises about the distribution to use (i know it's 
a very personal opinion... i thought of rh 6.2-sparc), but - mostly - i would 
like to know if the smp on the machine is supported (the guy who is about 
selling me the machine says it does, but i read somewhere - i think on a smp 
howto - that smp doesn't work on sun4m machines).
thank you in advance,
ciao
