Address Multiplexor and Decoder

A project log for ED-64: A discrete 8-bit computer

ED-64 will be an 8-bit computer built with discrete components, and will feature a ferrite core memory (documented as a separate project).

The next board to be added to the system - it selects between Address Register and Manual Address entry, and converts the selected address to Row/Column selection in the core memory. Pictured here with 6 partially-complete 2:1 mux modules yet to be installed:

Note that all components get a liberal application of cat hair before installation.

I am not sure your cat approves of your ESD procedures.  Maybe you need to get him a grounded wrist strap? :-)
