For byte pumping, the 6502 is probably better than any 8088.  Based on the
memory cycle time, a 10MHz 6502 is roughly a 40MHz 8088.  Certainly an
8088 would do some things better, but if all the IOP is doing involves
"interrupt -> grab a byte -> rti", the 8088 may even be less efficient.
And you don't find the 8088 as a standard cell in everyone's standard
cell library....
