8080 vs. 8080A

Just WHAT do 8088/8086 features and creatures have to do with the i8080?

Hadn't heard anything of an 8088/86 series bug but I know there's a 32 bit
applications lockup problem in some 386DX-16's and the well known floating point
math problem in the original Pentium series.

Can anyone here describe the technical differences between
an Intel 8080 and Intel 8080A CPU?

The ONLY ref. I have been able to find seems to indicate that there was a bug in
the 8080 and as a result it would only work with low power TTL?

The problem was fixed in the 8080A and it would work with
standard TTL?

Does this make sense to anyone?

Could anyone put this into laymans terms for me?

Thanks,
