I'd say you've got it backwards - Autodesk began using the 'A' logo in the early 80's and shipped on 5-1/4 floppies - at a time when very few computer users had mice, tablets, and (VGA/EGA) graphics-capable displays.

I see how that reads now; I wasn't intending to say who had it first, just saw Autodesk for the first time and that popped into my head.
