The Memotech RS128 — The Business Memotech
The Memotech RS128 was the business-oriented variant of the Memotech computer line, featuring 128 KB of RAM and CP/M compatibility — transforming the MTX’s home computer architecture into a credible business machine. Running CP/M gave the RS128 access to the extensive library of business software including WordStar, dBASE, and accounting applications. The expanded memory and professional operating system positioned it as a serious business tool rather than a home computer.
Memotech’s Business Pivot
Memotech’s development of CP/M-compatible business machines reflected the company’s attempt to find commercial viability after the consumer home computer market proved so difficult. The business market offered better margins and less price competition from Sinclair and Commodore, and Memotech’s reputation for build quality was an asset in corporate environments where reliability mattered more than cost. The RS128 represented this strategic pivot — leveraging the MTX’s engineering quality in a market that might better appreciate it.
