[CQ-Contest] Contesting Computer

[Jim Reisert AD1C]

I concur with John.  I built a couple of these machines last winter, albeit
with a different motherboard (K7VEM-Pro).  It's a good compromise in being able
to use an ISA card (like a 16-bit Soundblaster that K6STI's RITTY software
requires), yet you can still run a fast AMD processor and the whole package
won't set you back a whole lot.

Remember, most DOS-based software requires a separate IRQ for each interrupt,
while most cards with Windows drivers can share a single interrupt.  In other
words, those interrupt-sharing cards won't work as you expect with DOS
software, so you better be able to put a 2-port or 4-port ISA card in your
system.

Finally, think about audible noise!  I generally replace the power supply fan
and case fan(s) with quieter parts from PC Power and Cooling.  Get a video card
like the Nvidia MX440 or 5200 that has a passive heat sink (i.e. no fan). 
Seagate makes some low-noise drives (Barracuda IV series).  The less noise in
the shack, the less fatigue during a contest.
