Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Professional 325 and Professional 350 were PDP-11 compatible microcomputers introduced in 1982 by Digital Equipment Corporation as high-end competitors to the IBM PC. Like the cosmetically similar Rainbow-100 and DECmate-II, they used the LK201 keyboard and used 400kB single-sided quad-density floppy disk drives, and offered a choice of color or monochrome monitors. Unfortunately for DEC, none of the three would be favorably received, and the industry instead standardized on Intel 8088-based IBM PC compatibles which were all binary program compatible with each other. In some ways, the PDP-11 microprocessors were technically superior to the Intel-based chips. While the 8088 was restricted to 1MB of memory because of its 20-bit address bus, DEC microprocessors were capable of accessing 4MB with their 22-bit addressing. But other factors would weigh more heavily in the competition, including Digital's corporate culture and business model, which were ill suited to the rapidly developing consumer market for computers.
