#Rumor Update
Untill the advent of Windows 3.x there was little that wouldn't run, hoever
slowly, on the old machines. Even when 3.0 came out, most stuff would still
run on a 286. It has been the last couple of years, and OS2/2.x that have
required a 386 or better. So the older chips have has a long fun, even in the
Dos world. and as long you are running straight non Windows programs, most of
the current stuff, will still run on the old machines. Even the latest Dos
6.21 will run on the old machines.
On the other hand, Amiga with a limited user base, and relatively small sales,
had to be backwards compatible to have enough base to attract developers. When
you figure that more Dos boxes get sold per year, than all Amigas ever sold,
you can understand why they can write software that demands newer technology.
