Ben Eater's 8 bit breadboard computer project on YT is well explained, and he sells the kits. I forget Ben's credentials, but he is a professor in CS somewhere. His teaching skill is remarkable.
Some poor sap made a more intuitive set of schematics that also breaks down the kits: https://github.com/Upcycle-Electronics/8-Bit-Breadboard-Computer
That same guy made some chip labels that some people find useful: https://github.com/Upcycle-Electronics/ChipLabels
That last one also has a link to a list of databooks on archive dot org. Get the 1996 Motorola CMOS logic databook as your primary starting point reference. That goes into a lot of the details about cross compatibility and exactly what works and what doesn't.
This was my first electronics project, and it turned out surprisingly well.
I started coding NES "games" and his video help so much with how to approach something like that. But not just that but basically everything you need grom reading diagrams to setting up a complier to create a rom file with particular structure! Highly recommend it, there is no comparison to my cs prof..
