First version of Omron's Price-Busting Desktop Calculator. 8-digit Vacuum Fluorescent display, four function calculator using a 3-chip LSI calculator chipset made by Nortec Electronics. This machine set a new low-cost benchmark for entry-level desktop electronic calculators. Interested in this version (Version 1) only. Cabinet colors may vary, but key to identification of the version 1 machine is the Omron 800 badge on the uuper left of the top of the cabinet.
