I came across this today: “Electronics engineer builds 1986 Macintosh Plus
clone”. Is there some reason one would want to do this? Not sure what the
point is but it proves it can be done!
Happy computing.

You could write a small section of your book on David Small
Rather than recreate the whole computer, he created a cartridge to convert
an Atari ST into a Macintoch emulator.

It can be done on a Raspberry Pi Pico, a sub-$1 microcontroller.

Replica and cloned boards are probably going to be more important as time goes by.

Don't be mean. You don't have to be mean.

It's a fair point. That would be a lot more work but it is eminently
doable, yes.
I don't know if you have ever heard of the PiStorm, but it works by
taking the 68000 out of an Amiga and putting an entire Raspberry Pi on
an adaptor board in the CPU socket.
To run the computer, the original PiStorm software initialises, pauses
the bus, boots Linux, loads a 68000 emulator, unpauses the bus, loads
the OS from Amiga media into the emulator on the Pi and then executes
it.
The original version ran at about 5x the speed of a 25MHz 68030. It cost £50.

Now there's a bare-metal emulator that's about 130x faster.
So, yes, if replacing just the CPU is possible, replacing the rest of
the logic board as well is just an implementation issue.

The entire case can just be 3D-printed:

SE's occasionally get battery bombed and I'm imagining that's the case in
mind, similar to the reproduction SE/30 boards (though they get it much
worse as the caps leak too). But even beyond that it's a pretty neat
project.

If this is DOSfox's clone, he also built a Lisa clone last year. Of
course, the point, like a lot of stuff in this hobby, is "because why not?"
