Address Mux/Decoder Completed

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).

See it cycling through the address space:

The bottom section multiplexes between 2 address sources: the address register and a manually-set address. The top section turns the selected address (blue lights) into a row/column selection for the memory (top right yellow lights).

I need some power splitter/extender cables before I can connect it to the FC memory, that's a project for this weekend.

Next panel: the address register itself.

Well done!

It's nice to see that the build quality matches the concept.

I'm going to put the video on loop and "RELAXEN UND WATSCHEN DER BLINKENLICHTEN"

Are you sure? yes | no
