On a related RS/Tandy note, in 2020 I discovered - to my “surprise” - that the USB/RS-232 adapter cable that I’d originally purchased at Radio Shack circa 2010-2013, was actually one with a counterfeit Prolific chip in it.
Which Prolific’s Mac drivers detected, and therefore refused to work with it.
*Thankfully* I had another dongle with me at the time, so I could do what I needed to, but… that Radio Shack USB/RS232 cable has since been relegated to G4-Mini-Only status as a result.
