TTL 8-Bit CPU better than Z80

YES! The FPGA works! It didn't work because I used one of the MODE pins as a normal I/O and when I would boot it it would not boot my program. I also changed the switches to just wires because that way I wouldn't have to worry about pull-down resistors. 

Please comment or follow! Thanks!

So the ALUI doesn't exactly work. I took the FPGA I was using and put it into a testing circuit. I'm testing it and it doesn't work. Trying to fix it hopefully I will find a solution sometime soon! If you have anything to say please comment! Thanks! Here's a picture:

I finally finished building the ALU part! Here's a picture. The FPGA in the middle does addition, subtraction, complement, and, or, xor, and shifts. The rest off the chips are buffers, comparaters, registers, and the A register. The eight LEDs are connected to the data bus. If you have any suggestions please comment! Thanks!
