The XRX-230 was likely manufactured during the , a period when Japanese semiconductor firms like Hitachi, NEC, and Sharp were flooding the market with cheap, reliable calculator chips. Xerox, not wanting to invest in expensive in-house chip fabrication, almost certainly sourced its components from Japanese OEMs, rebadging the units for the North American and European office supply markets.
While Xerox is primarily known for enterprise-level imaging and printing technology , such as the Xerox C230 Color Printer
