In this video I take the multibus computer that I've been showing in my previous videos and I turn it into a nixie tube clock. Nixie tubes were display devices popular in the 60s, and used a series of filaments (one per digit 0-9) together with a gas and a high-voltage anode to light up the individual digits. They were popular in clocks, calculators, and scientific instruments. Multibus was a computer technology that was popular in the 70s and 80s, beginning with the 8080 and similar CPUs and running up into the later x86 cpus like the 80486. The most popular multibus were the 8080 and its variants like the 8085. In this video, I use an 80/24a multibus CPU which features and 8085 CPU together with 32K of EPROM and 8K of RAM. I add my own board which fills out the RAM to 64K and adds an emulated disk, then I add the nixie tube board. I developed a series of "multimodules", small plug in modules that add RTC, GPS, and speech synthesis. After I show off this basic computer, I reassemble it using the original multibus floppy controller, the SBC-202. For more vintage computer projects, see https://www.smbaker.com/
