    In a recent article to the net someone compared the T11 and 8088
in the Dec 350 and Rainbow respectively.  I'm not sure but I think
one of the instruction timings was off.  Were it compares:

               T11
               ADD R0,(R1)       2.8us

               the 8088 timing for this is (5mhz)
               ADD BX,(SI)       18cycles or 3.4us not 5.8us

This shows the 8088 is very close in speed for simple operations like
add and subtract.  An 8086 would have a wider memory bus and would
