it's IS a SIO save for it supports 8080/8085/8088 interrutpts instead.
Even the register addresses and functions are the same save those for
the interrupts. 
Someone once told me (could be urban legend) that the same guy designed
both chips--once for Zilong and then for Intel..

Definately urban legend.  If only because it was licensed to Intel from
NEC who designed it.  Early intel 8272s were old NEC mask.  I even cleaved 
an early Intel marked ceramic part for a customer to prove it.  The design 
came from NEC Japan. 

Stuff you learn by being there.
