Very related but self promotional—I have a hobby business selling restored Mac mini G4s. I clean all of them internally, upgrade them with 128 GB SSDs, max them out at 1 GB of RAM, put a new clock battery in, and pre-install the Mac OS 9 Lives hacked version of Mac OS 9 that runs on them. You can buy one from me here:
I don't think I'll start pre-installing System 7 since most of my customers are using Mac OS 9 (and the domain is os9.shop!), but you could certainly get a machine from me with Mac OS 9 and install System 7 yourself if you so desire.
My customers have included a lot of real businesses running legacy software who want the fastest, least intrusive, and least energy intensive Mac OS 9 desktop machine they can buy. I've sold to dentists, veterinarians, museums, and auto repair stores. You'd be amazed how many people are running Classic Mac software in 2025.
