| | DEC Alpha - Wikipedia, the free encyclopedia |
 | | Ironically, in mid-2003, as the Alpha was about to be phased out, the fastest and second fastest computers in the U.S. were both implemented using Alpha processors (in the case of the former, a cluster of 4096 Alpha processors). | | | Compaq announced that computers using Alpha would be phased out by 2004 in favour of Intel's Itanium. | | | DEC management doubted the need to produce a new computer architecture to replace their existing VAX and DECstation lines, and eventually killed the PRISM project in 1988. |

| | DEC PRISM - Wikipedia, the free encyclopedia |
| | By this time DEC was already working with the MIPS R3000 design for workstation machines, and had recently formed the Advanced Computing Environment consortium to popularize MIPS-based machines. | | | The VAX is often used as the canonical example of the "perfect" CISC instruction set, so such a conversion would not be simple. | | | It was the final outcome of a number of DEC-internal research projects from the 1982-85 time-frame, and was at the point of delivering silicon in 1988 when management cancelled the project. |

| | The Digital Equipment Multia was DEC's attempt to build a network-friendly workstation that was more of a "network computer" as originally conceived by Larry Ellison of Oracle - where the computer was a CPU and memory and display, with little else, and storage was mostly on the server side. | | | From the start, the machine was designed to use NT for Alpha. | | | In an effort to squeeze the most amount of computer into the smallest possible space, DEC cut a lot of corners, and ended up using more "laptop" technology than anything else. |

| | DEC doesn't document what the codes mean, though we can sometimes piece it together using various header files and source code that have been made redistributable. | | | Upgrading the firmware on a 3000/400 can be a dangerous operation, as it needs to have a sufficiently new SROM chip or else an upgrade from an old version of the firmware to a fairly new one will trash the system and cause it to machine-check at power-on. | | | If you try to set up a Digital UNIX 3.x (formerly DEC OSF/1) system as an NFS server containing NetBSD diskless root partitions, you'll run into a problem: Digital UNIX 3.x does not properly handle NetBSD device nodes. |
