and IIvi / Performa 600. Power 601 The DayStar Power 601 was an upgrade card fitted with either a 66 or 100 MHz PowerPC 601 and 256 KB of Level 2 cache. 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. High-performance Macintosh clones In 1995, the company engaged with Apple in co-development of the first dual processor system, sold only as an upgrade by DayStar. Then, in 1995, DayStar received a license from Apple to produce Macintosh clones and the industry's only multi-processor Apple systems, notably the DayStar Genesis MP dual and quad processor systems built around the PowerPC 604 chips. In retrospect, the Genesis MP is considered one of the most influential Macs of 1995, and one of the 25 most influential Macs for the first 25 years of the Mac product line. The license for all clone manufacturers was for version 7 of the operating system, but when Apple did not extend the license to version 8, it effectively canceled the program for all the clone companies. DayStar Digital eventually dissolved as a company in July, 1999.
