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

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

(I have a soft spot for 68k.)

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

Or are you thinking of 68000 SBCs?
Z80 CP/M machines were still competitive in 1981-1983 (Osborne, Kaypro) I've
never seen a 68k SBC. Have I missed out something along the way? Is
there a
community for 68k SBC's? Kind regards, Andrew
I guess the original hacker scene for the 68K was around Hal Hardenberg’s
newsletter: https://en.wikipedia.org/wiki/DTACK_Grounded
The ready-made 68K SBC’s only arrived 1984-1985:

one)
https://en.wikipedia.org/wiki/Atari_ST
https://en.wikipedia.org/wiki/Macintosh_128K
https://en.wikipedia.org/wiki/Amiga_1000
All these machines are rather similar at the hardware level - 68K
processor, RAM shared between CPU and display. Only the Amiga had a
(simple) hardware GPU.
What set the SUN-1 apart was its MMU, which none of the above have.
What influenced the timing was probably that Motorola made the 68K more
affordable by the mid-80’s.
