I run grass under linux on a 386sx-25mhz w/ 9MB of ram, 16K cache, a slow 
Trident video card, a poor 14" monitor w/ .52 dot res. (640x480x8), and
2 ide HDs (1=340MB, 2=100MB).  I have a 387, but linux does have fp math 
emulation code that can be configured into the kernel in the absence of a

The whole thing actually didn't seem too gawd-awful horribly painfully slow
until I was given an account on some Sun or other running Arc-Info so that 
I could finish off my PhD work.  Now I cringe every time I bring up grass on 
my home pc.  But then I used to cringe every time I brought up Word Perfect
on my old XT after I bought the 386sx.

An 80486sx should be fine, but invest in at least 8MB or more of RAM.
