DayStar Digital, Inc., was a company founded in 1983 by Andrew Lewis as a subcontract manufacturer of electronic assemblies and circuit boards.

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.

DayStar became known as the leading "speed shop" for Macintosh computer systems; it won virtually every Mac editorial award given for product excellence and had the top rated brand among peripheral manufacturers.

The Power 601 gave owners of a few 68030 based Macs an upgrade path to the new PowerPC architecture, using the Processor Direct Slot of the IIci, IIvx and IIvi / Performa 600.
