Grundy sold three models of the NewBrain. The Model AD had a one-line by 16-character LCD built in. The less expensive Model A lacked the LCD as well as a reset and on/off buttons. A Model M was an AD with battery power, making the NewBrain a portable. The NewBrain is popular among collectors of British micros.
