Yeah, people don't realize that the operating systems we have today arise from devices about as powerful as some of these microcomputers. Removing the complexities that have been added to the x86 platform itself and being able to see "oh when this pin goes high cause I pressed that momentary button the CPU runs the code at this memory address" things can really start clicking. A great youtube creator I recommend for those types of explanations (he's making his own CPU out of base components) is Ben Eater and specifically his 6502 series, but the series on how USB keyboards work is also quite instructive for people looking at the hardware at that level of detail.
