DayStar Digital, Inc. was a company founded in 1983 by Andrew Lewis as a subcontract manufacturer of electronic assemblies and circuit boards. In 1986, the company released memory upgrades for Apple Macintosh (Mac) computers as its first products, and in 1987, DayStar began to market processor upgrades exclusively for the Mac, the first being for the Apple Macintosh II computer. The company focused exclusively on this market for the full range of Mac computers through 1995, utilizing the Motorola 68030, 68040 and PowerPC 601 processors. These upgrades were installed directly into the PDS slot of various Macintosh platforms, as on the Macintosh IIci, or via an adapter. DayStar became known as the leading "speed shop" for Macintosh computer systems; it won virtually every Mac editorial award
