8080 vs. 8080A

My 1978 Intel Component Data Catalog has a 8080A / 8080A-1 / 8080A-2 data
sheet copyright 1977 (page 11-11 to 11-18). Just under the title is the
following line.
"The 8080A is functionally and electrically compatible with the Intel 8080."

I will look around for older catalogs. I have more Motorola 6800 datasheets
than Intel. This could be like the difference between the MC6820 and MC6821
Peripheral Interface Adapter. That was some small electrical specification
on an I/O pin that I can't remember now.
