The 8530 is a useful part for dedicated purposes, but isn't it severely
bandwidth cramped?  I am thinking that it's the serial chip in the
Sparcstations, correct me if I'm wrong.  A few years ago I was pondering
making a 'dialup connecting system with NAT server' out of a
SparcStation Classic (the little lunchbox type Sparc).  I discovered
quickly that the serial ports on the Sparc are VERY speed constrained
because of the 8530 chip.  It would have been impossible to connect my
USB Courier V-everything modem to it at, say 57,600 baud, because the
8530 just plain won't go that fast.
