I notice that the Intel datasheet for the 8086/88 (Microprocessors
vol. 2) doesn't give the clock counts for the different instructions,
unlike the sheets for the 286/386/486.  Is there another reference for
this info?  In particular I want to know how many clocks it takes to
do a 16-bit integer multiply, and also a 32->16,16 divide.  Also, does
anyone know if the NEC V20 does these operations faster than an 8088?
(Yes, some people still write programs for these processors).  Thanks.
