Well, there are only 2 "A" models of the Celeron. The 300A to distinguish it from the cache less 300, and the 533A which is a Coppermine based, to distinguish it from the Mendocino based 533.

1000a too isn't there? Or was that a p3?

Now its 5 Celeron A-s, but 3 of them are from Tualatins. 😀
There are at least 3, maybe more. I have 1000a and 1100a
Intel Celeron 1000A (SL5VP)
Intel Celeron 1100A (SL5VQ)

Yes, the Tualatin Celerons.

Oh, yeah. Forgot the Tualerons ... my bad 😀

One more A from Coppermine-T, but not from Desktop line. 😀

Coppermine-T refers to a budget Intel processors, part of the Coppermine family, built on a smaller 180nm process, designed for Socket 370 (FC-PGA/FC-PGA2) and known for its lower power use and "Tualatin-like" compatibility, bridging the gap between older Celerons and newer Tualatin. https://www.cpu-world.com/Cores/Coppermine-T.html

Coppermine-T Celeron, Mobile Intel Celeron 800A exist, this is mobile, but there are Pentium III-s with Coppermine-T at Socket 370,
but no Celerons with S370. https://www.intel.com/content/www/us/en/conte … -datasheet.html
