Busicom was the brand name used for calculators made by Nippon Calculating Machine Corporation of Japan. They entered the market of electronic pocket calculators already in the year 1971 with the famous Handy LE-120.
If you read the name "Busicom" you'll think about INTEL and the birth of the I-4004 microprocessor. If know the story about the first single-chip calculator circuit you'll think about MOSTEK and the Busicom 60-DB.
Busicom 100-DA is a simple desktop calculator powered by the Texas Instruments
TMS0106 circuit found in calculators like the Canon
L100S and the TI-3500.
The display found in the exec 100-DA is similar to the Panaplex style found in the early desktop calculators manufactured by Texas Instruments.
The Matsushita display module uses a complete different construction compared to the Panaplex™ developed by Burroughs.
