Connect the first consumer-ready mouse to any modern USB-C computing device: Mac, PC, even iPad!

I was frustrated by existing adapter solutions for the M0100, so I created a beautifully era-appropriate adapter that is USB-C native and can use any cable you want. I use it in workshops with my dedicated Mac Paint easy timelapse and clean screenshots emultor page (https://juliendorra.com/macintosh/), but of course it works with any emulator, or even with modern apps!

The first Macintosh mouse, the M0100 model, was the very first industrialized, consumer-ready, large-scale produced mouse. It is an incredible feat of design and engineering: the young design team at Hovey-Kelley managed to get from $500 mouses that needed regular tech maintenance like the ones at Xerox PARC to a $25 mouse that users can clean up in seconds. Most of them still works today! And as they were produced in the hundreds of thousands, you can find one anytime on second-hand marketplaces for a reasonable price.

Using a M0100 mouse on a modern computer is perfect if you want to really understand and feel what it was to use a Macintosh in 1984, but you can't justify the space or cost of a full 1984 Macintosh.

I especially love to hand the M0100 mice to my design students so they can draw in Mac Paint with the real pointing device it was designed for by Bill Atkison and Susan Kare. Using Mac Paint with the M0100 mouse always blows their mind and creates a incredible conversation about design, tools, and the evolution of (or lack of) the mouse-based computer.

This adapter is based on RP2040 Zero and use a custom PCB board to connect it to the DB9 connector (Yes, it is actually a DE9 connector! But everyone calls it DB9) .

I created two different housings, the first one is for the more common rounded connector, and the second one is for the rarer chunky connector (I had to hunt down one of these mouses to be sure make it at the right size!). So you can pick the version that looks best with your mouse. I use an 'Universal Grey' color for the housing, as connector color varies a lot from mouse to mouse, due to age and changes in processes, so getting an exact match covering all connectors is impossible. I found that a neutral grey was working best in the end.
