Interesting interview with Paul Lutus / HP-65 mention

[Sylvain Cote]

Extract from "Apple II History" ...

"GraFORTH, written by Paul Lutus and published by Insoft in 1982, was a very fast compiled implementation of Forth, which ran under DOS 3.3.
It was unique to other versions available on the Apple II in that it included the ability to draw on the hi-res screen using Turtle graphics, much in the same way as Logo."

"Lutus also wrote a more robust version of this language, called TransFORTH II.
Released the same year as GraFORTH, Lutus in the accompanying manual stated that he had designed it to be “a general purpose scientific and business language” for the Apple II."
