Not to sound like a snob, but it really is time to get Windows. You
can't expect software manufacturers to cater to the outdated. You
should be able to pick up a cheap 486 for around $500, just a little
more than you paid for those two calcs. A 486 can easily run Windows
3.x, and maybe even Windows 95.
