I've got an empty PowerBook Duo in need of a complete rebuild with current LCD. CM4 setup won't fit, that one's going into my original, bought new PowerBook 100.
Can any useful emulation run on a Raspberry Pi Zero? CM4? CM5?

Might as well ask here, topic title edited within edit window:
Raspberry Pi Compute Module 4 harnesses the compute power of the popular Raspberry Pi 4 Model B
Raspberry Pi Compute Module 5 is a system on module that delivers the power of Raspberry Pi 5
Going with the CM4 because it's expensive in the maxed out config I have. The I/O card is perfect and can be upgraded with the CM5 Compute module. I've got plans to play around with another project or two, the I/O boards are relatively inexpensive and I can play musical chairs with the Compute Module. Knowing myself, the CM6 will be available by date of completion.
I doubt the CM6 will be backward compatible with the CM4 I/O board as it will have a lot of additional pin connections. The CM5 board I wound up with at no cost because I ordered it by mistake and seller didn't want it back. Their admonition to be more careful in the future has been heeded., my bad. Anyway, the CM5 I/O board board is not at all well suited to my needs and the CM6 will likely be a worse fit.
However the additional oomph of a CM5/Raspberry Pi 5 should give me a lot more power for emulation tasks, no? CM4 is a great Linux platform, but a great emulation platform for the PowerBook form factor is the goal here. Might the CM5 upgrade give me the capability of running significantly higher OS level emulation?

Depends on what you want to emulate. I've been using Mini vMac on Raspberry Pis since the RPi3. I experimented with various OSes including RPiOS and DietPi without a desktop. I built Mini vMac with SDL and wrote a script so Mini vMac would be launched when the RPi3 booted.
This approach also works on the RPi4, 400, 5, and 500. I experimented with variations including Basilisk II and Sheepshaver.
Now we have more options. MAME does a pretty good job emulating 68K Macs and is easily built the same way I described, a "lite" version of an OS without a desktop, build MAME with SDL, and create a script to launch MAME when the RPi boots.
Theoretically you could do this with Snow as well but I haven't tried it because over the last few years I've been spending my time with real Mac hardware.

You should definitely check out MacintoshPi.
I actually have a Macintosh Classic II case with an integrated LCD display running this setup, and it works great! The performance is solid.
