Is this a Prototype?

I bought a set of old CPUs from scap gold auction last December. One of them is a HP 7200 with the following information:

-1, 2
PROTO

1FQ4-0004

HPfc IFQ4-0005 9151
USA 9529 1125 3.0

Is this a Prototype CPU?

By the way, It came with two chips (Please refer to 386-HP-unknown and 387-HP-unknown. Does anyone know what's it?

Thanks,
