Introduction of the Z-80 SoftCard

Microsoft publicly demonstrated the Z-80 SoftCard in March 1980 at the West Coast Computer Faire, introducing its first hardware product and a way for Apple II users to run CP/M software. The plug in expansion card added a Zilog Z80 processor to the Apple II, allowing the system to operate under the CP/M operating system, which was widely used for business applications at the time. By enabling CP/M compatibility, the SoftCard opened access to a large library of existing programs without requiring users to purchase a separate computer. The Z-80 SoftCard was designed to fit into an Apple II expansion slot and relied on the host machine’s memory and peripherals. After installation, users could boot CP/M from disk and run software written for Z80 based microcomputers. Microsoft marketed the product as a practical bridge between the popular Apple II platform and the growing CP/M business software ecosystem. The SoftCard became commercially successful and, for a period in the early 1980s, was reported as one of Microsoft’s top revenue generating products, reflecting strong demand for CP/M compatibility on Apple hardware.
