I thought about Engineer Sample at first but Gennadiy didn't marked it as ES in his collection. I see it on polish auction ... I preparing price to bid what depends on FPU value.

Here is a full list of prefixes - in case if it's needed:

A - automotive operating temperature range
I - Industrial grade
L - extended temperature range with burn-in
Q - commercial temperature range with burn-in
T - exended temperature range without burn-in

Do you mean identification table for 8087? It already has L, Q and T prefixes:

http://www.cpu-world.com/info/id/Intel-identification.html#8086__8087_and_8088

I don't know if 8087 co-prococessors with 'A' and 'I' prefixes exist.
