i know this is an old pose but i have some 22v10's, what kind of stuff have you made with them? using one as a bargraph driver or shift register woud be nice for my projects since i have some neon clock displays and uusing one to multiples it would be cool, its an old gold ceramic 22v10, but its one time programable only sadly, but i bought others that are reusable, but still no way to program them tho
