I first found this ad, MMD1 stands for Micro Mini Designer. Nice big box. And breadboard. Octal programming.
Funkenzupfer obviously has this device (next to some other rare ones) and some more photos
Later I found another ad
and this site about the Apollo181 4-bit CPU and other projects from the Bugbook book series with schematics and other info
