I really enjoy the brief period just after the release of IBM PC, where manufacturers could see where things were heading, but were still trying different things to set themselves apart.
Sirius 1 had the weird floppy drive and unusal high-res graphics. Apricot had Display-in-keyboard and compact form factors. Olivetti had charming italian design and the strange upside-down motherboard (when battery leaks it drips down instead of eating the PCB, talk about ahead of its time!)
All ran MS-DOS but not "PC compatible", so none of them really took off. Then everyone started to do 100% compatible clones, and it was a race to the bottom.
However if you want to go the other way and use USB keyboards on ADB mac (and many others), check out my USB4VC project: https://github.com/dekuNukem/USB4VC
