(*) I collected the following date codes for the various types of 132-pin chips (lowest-highest datecode):

0 (earlier version w/o double-sigma): none
1 ("double-sigma"): 3818
2 (80386DX-xx IV, double-sigma, Intel + i386 logos): 9907-9924
3 (same as 2 w/o "IV"): 8927
4 (same as 3 w/o "double-sigma"): 9949-9037
4b (same as 4 but w. smaller die): 8127-8129
5 (i386^TM DX^TM logo, smaller die): 8132-8133
