Based on his royalty agreement ($7.50 per unit) and the stated total sales of around 100,000 units, he made $750,000 in royalties. Nice! Sorta wish I got royalties for my projects....

Do people still do royalty based contracts? I wish they did.

And those are 1987 dollars. That's roughly $1.4 million today.

Is there a context behind the posting? Are we all saying this is prior art for some UI patent somewhere?

No context in particular :) Just an observation of how the "inertial scrolling" people are raving about on the new iDevices has a history deeply rooted in Mac folklore (Andy Hertzfeld was part of the original Mac team).

Also note mention of hysteresis and Floyd-Steinberg Dithering which are worth reading up on.

i've had a couple proposals for projects that offered a perpetual royalty instead of upfront payment. i had to weigh the cost of development against the feasibility of the product "taking off" or just dying on the table and earning nothing.

the switcher ( http://www.folklore.org/StoryView.py?project=Macintosh&s... ) story is also pretty interesting. i can't believe apple paid that much for what seems like a (relatively) small utility.

"The program is only half finished, and if I don't think you're paying me fairly, I won't be motivated to finish it."

Wow, this guy made 150k while he was about to make 750k from the Thunderscan stuff? Incredible stories.
