Not quite - the ECU did in software what that older hardware did.
On the older cars, it was fun to disable the electrical connector to the hardware and get a good series of pop-pop-pop. Not nearly as dramatic as turning off the key with the gas pedal on the floor for a brief coast-down, then switch the key back on. BOOM! Hahahahaha. Used to be a fantastic attention getter when we were 16!

Going back further...
On my V6 German Capri's(1976 and 1977) there was a vacuum decel valve/diaphragm behind the air(smog) pump. Also a small inline check valve to prevent reverse vacuum flow. These were there specifically to prevent backfire under decel.

Fiats were so technically superior (Haha) they used electricity for that valve
Yes, I was a certifed Fiat mechanic back in High School/College - about the timeframe you mentioned. Unlike the Maytag Repairman, there was PLENTY of work avail. if you could fix a Fiat!
