I agree, but don't you mean 24-bit address space?  A 20-bit address space is
1 Mb which is the 8086/8088/80186.  My 386SX motherboard manual says it has a
24-bit address space (16 Mb).

As for Unix, well, I'm running SCO Xenix 386 2.3.3 with everything but the
networking packages and Xsight.  No problems.  My only complaint is lack of
hard drive space and the fact that my motherboard can only handle up to 4 Mb
of physical memory on the motherboard.  Oh well.  Such is life.
