I loved the 68K and built several boards with it, although my board skills were maxed out after the 68010. I had a PT68K2 (http://bitsavers.trailing-edge.com/pdf/peripheralTechnology/...) and several other commercial 68k machines including an Atari 1040ST and wanted a Falcon.

I still have all my original reference material, and this book, http://www.amazon.com/MC68000-Assembly-Language-Systems-Prog... was one of my favorite computer books ever--I devoured that thing.

I still actually reference that book, and a couple others of that era, regarding microcontroller interfacing, even though I've moved on to Arduinos, RPis, and the bazillion other incredible SoCs I embed into stuff all the time now.
