Building CERBERUS 2080™, my dream childhood computer: Episode 10

As an 8 year old child, I dreamed of one day building my own 8-bit microcomputer. Motivated by this dream, I went to computer engineering school at 17. For almost thirty years since, however, the dream has lain dormant and forgotten. But no more: follow me as I honor the child I once was, and build the best late-70s-style microcomputer -- with vintage technology -- one could hope to have.

CERBERUS 2080™ is not only a brand new, elegant and authentic retro-computer, it is also a fully-documented, open, educational platform for students and hobbyist who would like to understand computers down to the gate level.

In this tenth episode, several updates are given on different aspects of the project. The final, fully-stable and reliable iteration of the video circuit is presented and discussed. The core of the episode, however, is a detailed discussion of the hardware design and test environment of SPACER, the third and final custom chip of the project. SPACER is then thoroughly tested in-system.
