there are add-on cpu upgrade products that cost nearly as much as a "bare-bones" system...
I saw some of them yesterday and forgot the link... but adding memory might be more effective than moving from 200 to 233MHz...
There are options... in both Dallas and Denver, a bunch of places sell off-lease P2-400 PCs for about $200...
Many city goverments offer recycled PCs for a nominal fee... maybe your son could volunteer to work with the recycling program and earn a faster used PC?
Good luck! Although employed, my PC is a P200MMX with 224 MB and a 2.1 GB drive... (was a P133 with 16MB mem and 250 MB disk when I got it) JTB
