C64 not a PC?
Those of us who get senior citizen discounts without asking may remember a time when "PC" simply meant "Personal Computer".
This was a bit before PC was re-purposed to mean only "bit for bit and bug for bug compatible with the IBM 5150 [1], complete with the BIOS and DOS not being able to agree whether the COM ports were numbered from zero or one, and for the love of all that is holy, _NEVER_ press the Turbo button"
[1] Those in the intersection of (computer nerds) and (union of (Van Halen fans), (law enforcement personnel), (police scanner obsessives)) got a laugh out of that designation. I guess Rat Mouth Florida never has any instances of people acting crazy in public (or has so many that they are not noticed).
