A new viewer referred me to dscript.org, another conlang site, where I found signs for logic gates. (I tip my hat to the referrer and to dscript.org.) I didn’t like dscript.org’s particular signs much, but they set me thinking about what I would like better, which I did, coming up with the below. I don’t like my results a lot either, but at least they are clear and constitute progress–they work. They might grow on me.
