National Semiconductor entered the market of Checkbook Calculators with the NS103 Data Checker in May 1978. It features Account Manager functionality with three permanent (till you remove the batteries) Memories and started a very successful product line. We discovered as of now seven different family members:
|• 1978: National Semiconductor NS103, 3 Memories
• 1979: National Semiconductor NS107, 2+1 Memories, Credit card size
• 1980: National Semiconductor NS103A, 3 Memories
• 1981: NSC Novus Electronics NS103A, 3 Memories
• 1981: NSC Novus Electronics NS101A, 1 Memory
• 1982: NSC Novus Electronics NS101A, 1 Memory, Gold
• 1982: This NSC Novus Electronics NS100A, 1 Memory, Credit card size
the featured NSC Novus Electronics NS100A Data Checker sporting just one memory and manufactured in 1983 in Taiwan reveals a clean design
centered around a NEC uPD1832G single-chip calculator circuit soldered on a
double-sided printed circuit board (PCB) powered by two
small LR54 batteries.

Don't miss the Corvus CheckMaster introduced by Mostek already in 1975. This rare product retains the balance of your memory even when shut off but uses power-hungry electronics.
