Tales of the M1 GPU

Probably not a fair comparison in some ways but this reminds me of that story of Woz making a disk drive controller with far fewer chips by being clever and thoughtful about it all. I’m probably misremembering this.

That's what pretty much what happened. The Integrated Woz Machine.

You’re talking about the Integrated Woz Machine. It was a custom disk controller that Wozniak created that was used in the Apple ][, /// and I believe on the original Macs. It was cheap, fast and worked.

And a later Mac, the IIfx, introduced I/O coprocessors to run the IWM, among other things. All part of the glorious wheel of reincarnation. [0]

Crazier yet: the IOPs on the IIfx were 6502-based microcontrollers.

The Integrated Woz Machine was the custom single-chip version of the Apple II floppy controller.
