One early manufacturer of printed circuit boards for microcomputers was he Santa Clara, California, firm of Microcomputer Associates. It sold circuit boards under the name of Jolt as well as a small amount of software. In 1975 the firm advertised cards of similar size that served as power supplies (see 1991.0891.01), microcomputer CPUS (see 1991.0891.30.2 through 1991.0891.30.4), 8K of RAM (see 1991.0891.30.5), and peripheral interfaces (this object). The boards sold both as kits and assembled. They could be stacked to form a microcomputer.
