Gene,
I found out the fix on my own with a little bit of investigaive reporting

.
My old trash compactor doesn't have a nice bypass trigger sticking out like a sore thumb right in the front like my neighbor's. Popped out the bag holder off the rail and after removing some stuff that was covering the rail-way, noticed the safety/bypass trigger and then pressed against it and... you guessed it...Voila!
