Interesting interview with Paul Lutus / HP-65 mention

[BobVA]

...developer of the Apple Writer word processor for the Apple II, and the cabin lighting for the Space Shuttle (!). Much like Woz, he got his start with programmable calculators.

Corecursive Interview with Paul Lutus

(My favorite part was the 1200 foot extension cord.)

The same guy who solo sailed around the world in a 31-foot sailboat. It took him 3 1/2 years and he had no previous sailing experience!

I remember reading about Paul Lutus and how he re-wrote the Aplle ][ operating system (is it true?). The picture I remember seeing is Paul standing next to single propelor airplane. The article said he lived in Oregon. He is one of rare kind of super geeks!

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."

I guess Lutus was a big fan of RPN (from using HP calculators) and decided to get into FORTH, offering two flavors (integer-based and floating-point-support) of the programming language.

Hello,

Paul Lutus has a personal website: https://arachnoid.com/
A lot of info and history of computing here, and a page on programmable calculators: https://arachnoid.com/programmable_calcu...index.html with some HP-25 and HP-67/97 programs.

Enjoy!

Vincent
