| I like the idea, that you have an ES and a production version of each. That's cool! |

This is a set of 80376 ES set, includes A82370 support chip and C27C203 EEPROM.
Intel 80376 was a variant of the Intel 80386SX intended for embedded systems. It differed from the 80386 in not supporting real mode (the processor booted directly into protected mode) and having no support for paging in the MMU. The 376 was available at 16 or 20 MHz.
It was replaced with the much more successful 80386EX from 1994. (From Wikipedia)

i487 Mechanical Sample, Retail version SZ494. Alitoutou has a SZES0 Engineering Sample which is very beautiful.
i487 is not really a math co-processor, it basically disable the 486 on board and take over 486's job. However it won't work if there is no 486 installed on motherboard. So 487 is a really tricky "co-processor"
