Hi, TRS80 here... late to the party...
Raided a bunch of Radio Shacks when they were closing with mixed results, some good, some meh. One of my two bag hauls at a store with lax rules on what a full bag meant had a register tape that was over 33 feet long. My son Pinball Jr. knows the guy who went into a 'Shack with his friend, when some R/S higher up said to "get the store cleared out" and made them an offer.. take the contents of the parts drawers NOW for a ridiculously low price. They rang up a single SKU which was the remaining drawer inventory and it was over $25K. Someone had left their cell with instructions to call if they were doing a final sale of whatever was left. He didn't answer his phone a couple times and missed out big time.

I didn't score any parts drawers, either they were spoken for, or they were too expensive.

Now, several years later, I often lament the passing of our local Shack. Like many other kids growing up in the 70's and 80's I spent a lot of time in them, playing with the TRS-80 (and even helping to sell a few when the store people weren't knowledgable about the machine), building things and reading Forrest Mim's books, and running in to grab a part to finish a project on countless occasions.
