Clock Halt Circuit with 4011 NAND Gate and 555 Timer

update: Schematic now available at https://excess.org/halt/
These videos are inspired by Ben Eater's videos, in particular his 8-bit breadboard computer series • Building an 8-bit breadboard computer!
Some ideas for enhancements to the clock module are from James Sharman's 8 bit pipelined CPU series • Making an 8 Bit pipelined CPU and from Julian Ilett's 555 timer video • 555 Timer Clock Circuit for 8-bit Computer...
