This is so not true. I wrote the TI 99/4 Logo at MIT (translated from an implementation in Pascal by Gary Drescher). The Apple II implementation was overlapping, started a little later, the guys doing it had the next desk. It was licensed by MIT to Terrapin Inc and released ('82) not long after the 99/4 version ('81). https://www.dropbox.com/s/migcvjvgu31qaz9/LogoHistory_Microc...
We also have Drescher's Pascal Logo incoming soon. Preview: https://github.com/PDP-10/its-vault/blob/master/files/aplogo...
Cool, though I have a printed copy of that. I looked through it recently trying to remember some details for an upcoming paper
