Minimalist Computer Build: Zeta SBC

zeta sbc v2 boardI’m building a Zeta SBC V2, a basic Z80 computer in the spirit of the N8VEM. I’m trying to kit it out mostly locally, which means extensive trips to Creatron, Supremetronics/Honson Computer (aka the basement of College Home Hardware), Above All Electronic Surplus, and Active Surplus.

Fun discovery #1: not all CR-2032 battery holders are the same size. This board call for the one just a tiny bit larger than the coin cell itself. Most of the ones with the retainer clip that goes over the battery are too big, and will prevent other components being installed.
