I have an A1010-style floppy drive that has a lovely, shiny Boing Ball logo instead of a checkmark. It is serial number XN1108119.
I'm reading the Platform Studies book by Jimmy Maher, and he suggests the boingball logo was used on early pre-release hardware only, until Commodore changed to the checkmark logo.
How rare is my floppy drive? Could it have been early pre-release hardware? It still works!
