I was going on a show special price I paid Cell Computing in November
for a 233MHz CardPC CPU with 64MB RAM together with an evaluation board
(the very large one), somewhere around $1,080 (they wanted $999 including
32MB, 64MB added a bit).  I was also figuring that a 233 MHz Pentium was
around 5 times the compute power of a 66 MHz 486, a considerably bigger
factor than the price difference, even at the EMJ price.  Seems to me
this makes the CardPC the clear winner in terms of MIPS per dollar.

Another issue is VGA, which comes with the CardPC, but which is $155
extra with the JUMPtec (assuming you get the Combo module with ethernet
as well, plus two more serial ports).  This further narrows the price gap.

These considerations only make sense if you're trying to build
a supercomputer out of a lot of these.  For one computer go for the
JUMPtec 486 unless you really need those cycles.  It's a much smaller
package with less demanding power requirements.
