Check out the ultra-rare MicroSCI HAVAC (Home Academic Very Affordable Computer), a compact Apple II-compatible computer originally developed during the early 1980s as a dedicated game system before evolving into a full Apple-compatible computer. Created by Southern California-based MicroSCI during the golden age of home computing and entertainment software, the HAVAC represents an unusual and little-known chapter in Apple II clone computer history.
Built around the 6502 processor, the HAVAC includes 64K of RAM, 8K of ROM, joystick support, serial and parallel connectivity, and a built-in single-sided floppy disk drive. The detachable 63-key keyboard closely resembles the Apple IIe layout while the system itself aimed to provide an affordable alternative to Apple hardware at a retail price of $799 USD. Although compatibility with Apple II software was generally strong, the system struggled with some Apple IIe-specific applications, CP/M software, and certain ProDOS configurations.
This video explores the hardware, ports, design, and history of the HAVAC while documenting one of the rarer Apple II-compatible systems encountered in the retro computing community. Despite its limitations and lack of expandability, the MicroSCI HAVAC remains a fascinating example of early 1980s computer design and the rapidly evolving home computer market of the Apple II era.
