Re: using din 4-pin trackball with USB

There's a few options. You can choose cheap, or easy, but no option I'm aware of combines both.

The Griffin iMate converted the 4-pin din Apple ADB to USB. But they command a high price on the used market.

Or you can roll your own with an Arduino microcontroller:

Or a Teensy:

* note that the latter two are actually meant for ADB keyboards, so there's still some coding needed to get a mouse/trackball working.
