This is a design for an 8 bit CPU built from 74HC logic chips.
It is totally just for fun. I may try to complete it at some point but for now it's only at the idea stage.
The design directory has a block diagram that is probably the most useful document for explaining how the CPU is intended to work.
One potentially useful component that is (probably) ready for use is a passive backplane design, which is in the backplane2 directory.
