AE86 4AGE *40* pin IC :)
175770-0032 01-2-135 8323 E13 - dissimilar part number... :(
Crystal pins 2,3, gnd pin 1, power 4,5, (7?).
This one is ceramic cased with a 0.5" by 0.5" metal cover.
All ICs in the other ECUs specified in the previous post were incased in
the black resin.

MF070?
There are a few ICs on this one: (descriptions from ic listing book).
NEC uPC451C quad op amp (14pin)
F(ujitsu?) MB4053 ADC 6 channel (16pin)
Toshiba TC4069 (hex inverter?) (14pin)
(Hitachi?) HA17901P quad comparator (14pin)
T2333? 9pin sil
And 2 ND 14pin DILs, and 2 ND sils (HC128, HE062).
I need to take a detailed look at the AE82 one because it appears to be a
lot different (from icq conversations).
Mos.
