I’m not a fan of self-boosting, but I realised I was remiss in not putting some hashtags on this post after it started gaining the small amount of traction it has.
For those who boosted or liked the original, I’m not asking or expecting a repeat. I just hope with these hashtags it gets a little more traction to acknowledge the genius of #BillAtkinson, who affected so many lives through the genius work he did.
I know he impacted many aspects of my life through the work he did on the Mac, the original System, and MacPaint, and it seems many others were similarly impacted.
It’s been truly inspiring for me to see Mac legends talk how he put the lie to the saying “Never meet your heroes”, as he seemed to have been a hero to many, and never a disappointment in person.
RIP, Bill.

Just a reminder that the original Myst was developed using HyperCard, one of Bill Atkinson’s many masterpieces. But I’ll always remember how he thought overlapping windows (or perhaps the smooth movement of windows over each other) was a solveable problem because he recalled seeing that Xerox had solved it (they hadn’t), so he just worked it out because he then thought it could be. An amazing mind, now lost to us. RIP Bill, and thank you!
Did you know: Engineer Ronald H. Nicholson Jr. was part of both the Macintosh and Amiga teams, and has his signature molded into the cases of the Amiga 1000 and the early Macintosh computers.

Anyone know what the CRT refresh rate on the original Mac / Fat Mac / Mac Plus is? 60Hz?

Let’s go back to Apple’s garage to meet the Lisa’s younger sibling, the Macintosh, and its OS! Is it a Lisa copycat, or are there any intriguing secrets behind it?

If anyone is wondering why: The Mac 128k needs raw quadrature encoder data from the mouse (half on the SCC serial controller and half on the VIA which sucks because I had to partially implement the SCC just for that).
Raw quadrature data gives you a "one step up/down/left/right" signal.
But the mouse deltas I get can be "5 up 3 left" so I have to convert that into one "pixel" deltas like up up up left etc.
So I use the algorithm to break down the deltas into units
So long story short, after changing the 3 to a 7 and cursing like a sailor....
Yeah.
The real MVP here is "Apple 400k Floppy Disk Drive - 6990285A.pdf", without it I'd be there for months.
(ok Mac Almanac II.txt and apple2_IWM_Spec_Rev19_1982.pdf helped too! And probably four other documents!)
Thank god they gave the checksum algorithm (I need it to encode the floppy image to a format digestible by the computer)
Im in ur virtual floppy, reading your boot sectorz (and calculating your checksumz)
Well my fake Mac 128k is able to read a fake sector header on my fake floppy drive spinning a fake disk at the proper (variable) fake speed. 
PROGRESS!
