Varilogic 2 by Grant Richter
PCB Layout
this module can change the logic between two gates with voltage control ,so depending on the voltage it can be and / or / xor
the table is borrowed from Richter's old page which can be still found at the wayback machine along with schematics and more info on this module https://web.archive.org/web/20140810101425/http://www.musicsynthesizer.com/DIY/Grant/grant_richters_synthdiy.htm
PCB Layout is still not confirmed as i don't know if i need this too right now ,i share it if anyone wants to build this .
