Well, the /usr/bin/X11 directory on my Sun 2/120 (68010 cpu, 10MHZ) is about 16MB, but the executable Xsun is only about a Megabyte. If there is adequate resolution on the 3b1's screen (though I don't see it running the 80x65 xterm windows legibly) I guess that it could be persuaded to run X11R4, but I'd re-format that hard disk, giving more space to swap, since there are LOTS of 1/2MEG executables in that directory, and you tend to have several loaded at any given time. Nothing is shown by size(1) to be bigger than 1MB, and virtual memory is a wonderful thing. (But don't ask ME to port it! :-) As far as speed goes, The sun benchmarks out just a bit faster on the dhrystone than the 3b1, both using gcc. However, screen writes are significantly faster to my perception in the Sun, so I guess that there's lots of special hardware in the Sun helping out there.
