No one has quite emphasized the important part:

        The Intel 8088 was the cpu used in the original IBM-PC and IBM-PC/XT

It's still available (I'm not sure if it's still being manufactured.)  In
fact, you can get full PC/XT-style motherboards for about $10 (last time I
saw some advertised.)  Such a motherboard is comparable in some sense to a
PIC, as is a full PC system, which you can generally find at garage sales,
in dumpsters, and at surplus stores, in amoungst the "too worthless to even
test" piles...

The NEC V-20 was an 8088 pin compatible with slightly better performance, as
well as an 8080 (z80?) compatibility feature...
