Charles Sanders Peirce ( intii lagu jiray 1880-81) wuxuu muujiyey in albaabada NOR oo keliya (ama haddii kale albaabada NAND oo keliya) loo isticmaali karo in lagu soo saaro howlaha dhammaan albaabada kale ee macquulka ah, laakiin shaqadiisa ku saabsan lama daabicin ilaa 1933. Caddaynta ugu horreysa ee la daabacay waxaa qoray Henry M. Sheffer sanadkii 1913, sidaa darteed hawlgalka macquulka ah ee NAND waxaa mararka qaarkood loo yaqaan Sheffer stroke; NOR macquul ah waxaa mararka qaarkood loo yaqaan fallaadha Peirce. Sidaa darteed, albaabadan waxaa mararka qaarkood loo yaqaan albaabada macquulka ah ee caalamiga ah. Su'aal: Waa maxay magaca rasmiga ah ee albaabadan?
