Here are some views of the five-dollar-wonder 1988 Camry ECM I got from the boneyard.

I counted:
17-microprocessors
13-transistors
3-solid-state relays
24-diodes
88-capacitors
164-resistors
4-unidentifiable components (Al thinks two of them may be crystal clock timers for logic)
Pretty amazing that all this can hang together for 22-years and 367,000 miles.To the Moon and halfway back!
