Well, my current motherboard uses 72 and 30 pin simms.  So, I can add
32MB of RAM to my current 16MB of RAM, and have 48MB, for only $240
according to your prices.  Or I can sell the 16MB of 30 pin SIMMS
for $120 dollars (again according to your prices), and it'll only
cost me $120 to upgrade to 32MB.

I've already gotten mail suggesting I switch to OpenBSD.  Well, I'm 
not currently looking at this solution, but why can't we have a
machine dependent bounce buffer solution while we wait for a machine
independent solution.  It's not like we don't have other machine
dependent code.
