DEC computers

AlphaServer is a series of server computers, produced from 1994 onwards by Digital Equipment Corporation, and later by Compaq and HP. AlphaServers were based on the DEC Alpha 64-bit microprocessor. Supported operating systems for AlphaServers are Tru64 UNIX (formerly Digital UNIX), OpenVMS, MEDITECH MAGIC and Windows NT (on earlier systems, with AlphaBIOS ARC firmware), while enthusiasts have provided alternative operating systems such as Linux, NetBSD, OpenBSD and FreeBSD.

The Professional 325 (PRO-325), Professional 350 (PRO-350), and Professional 380 (PRO-380) are PDP-11 compatible microcomputers. The Pro-325/350 were introduced in 1982 and the Pro-380 in 1985 by Digital Equipment Corporation (DEC) as high-end competitors to the IBM PC.

The Itsy Pocket Computer is a small, low-power, handheld device with a highly flexible interface. It was designed at Digital Equipment Corporation's Western Research Laboratory in Palo Alto to encourage novel user interface development—for example, it had accelerometers to detect movement and orientation as early as 1999.

The Digital HiNote was a series of laptop computers manufactured by Digital Equipment Corporation (DEC) from 1994 until 1998 and by Compaq from 1998 until 2002. It was generally positively reviewed by technology journalists. The series consisted of the VP and Ultra models which were based on the i486, Pentium, Pentium MMX and Pentium II. After Digital was acquired by Compaq in 1998, the series was phased out.

VAXmate was an IBM PC/AT compatible personal computer introduced by Digital Equipment Corporation in September, 1986. The replacement to the Rainbow 100, in its standard form it was the first commercial diskless personal computer.

The Rainbow 100 is a microcomputer introduced by Digital Equipment Corporation (DEC) in 1982. This desktop unit had a monitor similar to the VT220 and a dual-CPU box with both 4 MHz Zilog Z80 and 4.81 MHz Intel 8088 CPUs. The Rainbow 100 was a triple-use machine: VT100 mode (industry standard terminal for interacting with DEC's own VAX), 8-bit CP/M mode (using the Z80), and CP/M-86 or MS-DOS mode using the 8088. It ultimately failed to succeed in the marketplace which became dominated by the simpler IBM PC and its clones which established the industry standard as compatibility with CP/M became less important than IBM PC compatibility. Writer David Ahl called it a disastrous foray into the personal computer market. The Rainbow was launched along with the similarly packaged DEC Professional and DECmate II which were also not successful. The failure of DEC to gain a significant foothold in the high-volume PC market would be the beginning of the end of the computer hardware industry in New England, as nearly all computer companies located there were focused on minicomputers for large organizations, from DEC to Data General, Wang, Prime, Computervision, Honeywell, and Symbolics Inc.
