hmm, that's too bad.

should be no problem, you just need to figure out how to send a break from the
agenda.  can't help you there though.

the sparc20 is never going to have the snappy graphics of the PC for a price
that you would enjoy.  the SX is an ok 24-bit framebuffer, but dog slow.

the way X works, the graphical abilities are determined by the server (the
machine with the graphics card) so you will get nice PC 24-bit color for all
your apps on the sun box.  if you are looking to do heavy 24-bit stuff like
gimp though, i would recommend a full duplex 100Mbps ethernet connection, or

it's got a little more CPU power than my sparc. :)  wav->mp3 is a CPU bound

figure out how to get your terminal (or terminal software) to send a BREAK on
the serial line.  sometimes you can unplug the serial cable and get it to do
a break, or after it has booted to the point that it doesn't see your keyboard
(where it complains about the keyboard missing) plug your keyboard in and use
it to generate the break (ala stop-a) although figuring out your terminal would
be the best solution.

depends on what you use to hook up with.
