Microprocessor Lean Burn part- please help
 

Hello:
Can anyone identify the part numbers of the early 1980s Lean Burn modules that are built like this?
These are the lean burn modules with a microprocessor.
Anybody have one?

Thanks!

We never opened them up to repair them only replaced. I'm guessing you're trying to keep it original, but those lean buns were a huge failure.

I'm looking for one of these for historical purposes.
Not to use.

Just think your house thermostat has more processing power than the lean burn setup…
