Upgrading the 1000 SX is pretty much useless.  First and foremost,
even with a NEC V20, the 1000 SX is far, far too slow.  I've run
DESQview and Windows on my 1000 SX with V20 and 8087, and it's a joke.
It takes minutes to run simple tasks under Windows, not to mention
complex calculations or graphs on Excel.

Also DESQview and Windows want EMS 4.0 memory.  I don't know of any
boards for the 1000 that will supply that.  The best I've seen is EMS
3.2, which is little better than a RAM disk (that's all DESQview will
let you do with EMS 3.2).  Even on an 80286 it's a royal pain to get
DESQview up 'n running.  The only practical way I know of is to buy an
All Charge Card, which gives the 80286 the memory-mapping features
that the 80386 has built in.  The DESQview and Windows manuals say
that multitasking is only achieved on an 80386 platform.  This is
because the 80386 can run many "mini" 8086's at a time.  On a 286 or
88, DESQview and Windows merely chop up the time slice.

My advice to to save your cash and get a 386SX when it's in your price
range.
