M68k was great and still is awesome for its time. 68000, if implemented in a FPGA would be perfectly useable in a way that Microchip uses MIPS core in ther micros etc. Unfortunately RISC-V is here, so this is getting less relevant. But still nice to have for some retro stuff, special micro or two etc.

ColdFire line. And I think some microcontroller, some of which might be available even today. I know that my old Tek Scope TDS-3054 has one.

however people don't give up, and for fun on hardware based on this cpu it implements everything .. here is someone who implemented java

IIRC the last code I wrote for a 6800 played a tinny version of "Hoedown" on a 1-bit speaker output while scrolling an approximation of "Emerson Lake Palmer" across the 7-segment displays in ~1977, but I worked on 68000-family graphics drivers and accelerator hardware (initially for X/Unix then MacOS) from the early 80's through to the early 90's. That extra '0' made a big difference.
Anyways, it's worth checking the article and bumping 6800->68000.

I am putting together a youtube video explaining these, but I even recently disassembled Duck Hunt for NES, which uses the 6502, and Defender the arcade game, which uses the 6809. If this interests you, the code is linked below.
I made a tool in ncurses on Linux that helped me put these together. It wraps around the ROMs, and you set the system state to each byte, and it spits out the code from the labels/comments I put "over" the binary. YouTube series coming soon!

but with RISC-V as someone said, this would make little sense ... unless there would be a licensed opensourcing of this architecture and somehow adapting it to RISC-V instructions, in the end RISC-V is just a set ISA right?
