FYI no lower case, also "contact the author for licensing". (The article is a neat story of digging into the history of the displays which are about to be going out of service, as well as some practical aspects of the font design - it's just not casually available.)
Honestly, I wasn't expecting this font to go anywhere, and then the SF Chronicle reached out, which has been lovely. Anyone who emails me can have a copy, I just haven't made an easy download link. I've thought about it since, but actually it's way nicer to hear from people and hear about what they're making. It is a community-driven project, and this slower form of distribution feels closer to my original intent. :)
