Any idea why you discovered this non-TI calculator within the Datamath Calculator Museum? Zayre Corporation sold in 1976 a slightly redesigned Novus 750 calculator as CONCEPT 10.

Dismantling this Novus 750 calculator manufactured in May 1976 reveals a very simple, yet efficient technology called chip-on-board (COB) technology. Instead of the traditional approach with a plastic-encapsulated Integrated Circuit (IC) soldered on the printed circuit board (PCB), achieves COB-technology direct wire bonding of the IC to the PCB.
