Debian already migrated to i686 as the minimum supported version a few years ago. i686 supports Pentium 3 which is the oldest processor in use on this thread. Some internet sites say that i686 is Pentium 4 and later others say that it is Pentium 2 or later. Others say that i686 is Pentium Pro version 2 and later. If it is indeed Pentium Pro and later then a lot of older processors are still supported: Pentium 2, Pentium 3, Pentium M, Celeron, Pentium 4 etc.

Hello,
Wikipedia states that the P6 (aka i686) line starts with the Pentium Pro:
https://en.wikipedia.org/wiki/List_of_Intel_CPU_microarchitectures#32-bit_(IA-32)
https://en.wikipedia.org/wiki/P6_(microarchitecture)
That is confirmed by Intel own doc (Intel® 64 and IA-32 Architectures
Software Developer’s Manual):
