There is an active community around DIY 68k SBCs these days. Some
representative examples:

https://www.eejournal.com/article/wallowing-in-68k-nostalgia/
https://www.ist-schlau.de
https://www.bigmessowires.com/category/68katy/
https://github.com/74hc595/68k-nano
http://mc68k.blogspot.com/2012_10_01_archive.html

There are even a couple of fairly advanced 68030 design floating around:

https://www.retrobrewcomputers.org/doku.php?id=boards:ecb:kiss-68030:start

(I have a soft spot for 68k.)

Well, Rob Pike designed one: http://doc.cat-v.org/bell_labs/blit/
