More numbers:
1987ish 3SGE (ST162)
	42pin D151801-2260, 6312-0035, 5L1010
		crystal pins 15,16, gns 21, power probably 41,42.

1989ish 7MGE (MX83) 3 large ICs, 2pcbs, lots of smaller ICs.
	42pin D151801-5690 (Some pins travel to a 26pin header-pad)
		crystal pins 16 and 17 thru 680R, gnd 20,21, power prob 41,42
	42pin D151801-8610
		crystal pins 15,16 (hmm?), gnd 21, power probably 41,42.
	64pin D151801-8650
		crystal pins 6,7, gnd 32, power probably 64.

199*ish 3SGTE (SW20)
	42pin D151802-3100
		crystal pins 16,17, gnd 21, power possibly pin42.
		14 pins travel to 26pin header pad (11 header pins gnd, 1 unused)
	64pin D151802-7340
		crystal pins 6,7, gnd 32, power probably pin 64.

All these are obviously ND. There's an '84 AE86 4AGE ecu also, but as it's
in the car right now it's kinda hard to look at.

The 26 pin header pad looks interesting in the newer ECUs.

I don't really have much info to share at the moment - given time
hopefully that will increase :)
