GatorBox
The GatorBox is a LocalTalk-to-Ethernet bridge, a router used on Macintosh-based networks to allow AppleTalk communications between clients on LocalTalk and Ethernet physical networks. The GatorSystem software also allowed TCP/IP and DECnet protocols to be carried to LocalTalk-equipped clients via tunneling, providing them with access to these normally Ethernet-only systems. When the GatorBox is running GatorPrint software, computers on the Ethernet network can send print jobs to printers on the LocalTalk network using the 'lpr' print spool command. When the GatorBox is running GatorShare software, computers on the LocalTalk network can access Network File System (NFS) hosts on Ethernet. Specifications * The original ''GatorBox'' (model: 10100) is a desktop model that has a 10 MHz Motorola 68000 CPU, 1 MB RAM, 128 KB EPROM for boot program storage, 2 KB NVRAM for configuration storage, LocalTalk Mini-DIN-8 connector, Serial port Mini-DIN-8 connector, BNC connector, AUI ...

MacIP
MacIP refers to a standard for encapsulating Internet Protocol (IP) packets within the AppleTalk DDP protocol. This allows Macintosh computers with LocalTalk networking hardware to access the normally Ethernet-based connections for TCP/IP based network services. This was an important bridging technology during the era when Ethernet and TCP/IP were rapidly growing in popularity in the early 1990s. Software implementing MacIP, such as MacTCP or Open Transport, was installed on the computer and a MacIP Gateway was placed elsewhere on the network. Applications that communicate with TCP/IP (such as Telnet) have their IP packets encapsulated in DDP for transmission across the LocalTalk network to the MacIP Gateway. The MacIP Gateway strips off the DDP encapsulation and forwards the IP packet on the IP network. The gateways were often implemented as part of a LocalTalk-to-Ethernet bridge device, small hardware systems primarily designed to allow communications between LocalTalk and Eth ...

FastPath
The Kinetics FastPath was a LocalTalk-to-Ethernet bridge (now referred to as a router) created in 1985 to allow Apple Macintosh computers (which at the time only had LocalTalk network connections) to communicate with other computers on Ethernet Ethernet () is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1 ... networks. The product had five significant revisions (known as KFPS-1 through KFPS-5) during its lifetime and was ultimately sold to Shiva Networks late in its existence. The original FastPath was developed to extend AppleTalk on Ethernet for Apple Computer, but from the beginning it was also modeled after an implementation of the Stanford Ethernet - AppleTalk Gateway (SEAGATE) created at Stanford University Medical Center by Bill Croft in 1984 and 1985. SEAGATE was a combination of hardwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Line Printer Daemon Protocol
The Line Printer Daemon protocol/Line Printer Remote protocol (or LPD, LPR) is a network printing protocol for submitting print jobs to a remote printer. The original implementation of LPD was in the Berkeley printing system in the BSD UNIX operating system; the LPRng project also supports that protocol. The Common Unix Printing System (or CUPS), which is more common on modern Linux distributions and also found on Mac OS X, supports LPD as well as the Internet Printing Protocol (IPP). Commercial solutions are available that also use Berkeley printing protocol components, where more robust functionality and performance is necessary than is available from LPR/LPD (or CUPS) alone (such as might be required in large corporate environments). The LPD Protocol Specification is documented in RFC 1179. Usage A server for the LPD protocol listens for requests on TCP port 515. A request begins with a byte containing the request code, followed by the arguments to the request, and is termi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Transport
Open Transport was the name given by Apple Inc. to its implementation of the Unix-originated UNIX System V, System V STREAMS networking stack. Based on code licensed from Mentat's Mentat Portable Streams, Portable Streams product, Open Transport was built to provide the classic Mac OS with a modern TCP/IP implementation, replacing MacTCP. Apple also added its own implementation of AppleTalk to the stack to support legacy networks. History STREAMS Prior to the release of Open Transport, the classic Mac OS used a variety of stand-alone INIT (Mac OS), INITs to provide networking functionality. The only one that was widely used throughout the OS was the AppleTalk system. Among the other protocol stacks supported, MacTCP was becoming increasingly important as the Internet boom started to gain momentum. MacTCP emulated the Berkeley sockets system, widely used among Unix-like operating systems. MacTCP and the previous generation AppleTalk library were slow on PowerPC-based Macintoshes b ...

MacTCP
MacTCP was the standard TCP/IP implementation for the classic Mac OS through version 7.5.1. It was the first application-independent implementation of a TCP stack for a non-Unix platform and predates Winsock by over 5 years. Released in 1988, it is considered obsolete and has reliability issues and incomplete features that sometimes prevent it from operating properly on the modern Internet. In addition, the API was unique to the Mac OS, and at least one developer released a Berkeley Sockets-derived API to make porting from other platforms easier. It was originally a substantial purchase, carrying a $2,500 price tag for a site license, with an additional $2,500 fee for commercial use. The price was lowered until by the mid-1990s it sold for $60. MacTCP was not included free with Mac OS until System 7.5, when the rising popularity of the Internet made it a necessity. Apple replaced it in 1995 with Open Transport Open Transport was the name given by Apple Inc. to its implementation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macintosh Finder
The Finder is the default file manager and graphical user interface shell used on all Macintosh operating systems. Described in its "About" window as "The Macintosh Desktop Experience", it is responsible for the launching of other applications, and for the overall user management of files, disks, and network volumes. It was introduced with the first Macintosh computer, and also exists as part of GS/OS on the Apple IIGS. It was rewritten completely with the release of Mac OS X in 2001. In a tradition dating back to the Classic Mac OS of the 1980s and 1990s, the Finder icon is the smiling screen of a computer, known as the Happy Mac logo. Features The Finder uses a view of the file system that is rendered using a desktop metaphor; that is, the files and folders are represented as appropriate icons. It uses a similar interface to Apple's Safari browser, where the user can click on a folder to move to it and move between locations using "back" and "forward" arrow buttons. Like ...

DE-9 Connector
The D-subminiature or D-sub is a common type of electrical connector. They are named for their characteristic D-shaped metal shield. When they were introduced, D-subs were among the smallest connectors used on computer systems. Description, nomenclature, and variants A D-sub contains two or more parallel rows of pins or sockets usually surrounded by a D-shaped metal shield that provides mechanical support, ensures correct orientation, and may screen against electromagnetic interference. D-sub connectors have gender: parts with pin contacts are called ''male connectors'' or ''plugs'', while those with socket contacts are called ''female connectors'' or ''sockets''. The socket's shield fits tightly inside the plug's shield. Panel mounted connectors usually have #4-40 UNC (as designated with the Unified Thread Standard) jackscrews that accept screws on the cable end connector cover that are used for locking the connectors together and offering mechanical strain relief, and can ...

Repeater
In telecommunications, a repeater is an electronic device that receives a signal and retransmits it. Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction. Some types of repeaters broadcast an identical signal, but alter its method of transmission, for example, on another frequency or baud rate. There are several different types of repeaters; a telephone repeater is an amplifier in a telephone line, an optical repeater is an optoelectronic circuit that amplifies the light beam in an optical fiber cable; and a radio repeater is a radio receiver and transmitter that retransmits a radio signal. A broadcast relay station is a repeater used in broadcast radio and television. Overview When an information-bearing signal passes through a communication channel, it is progressively degraded due to loss of power. For example, when a telephone call passes through a wire telephone line, some of the powe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
19-inch Rack
A 19-inch rack is a standardized frame or enclosure for mounting multiple electronic equipment modules. Each module has a front panel that is wide. The 19 inch dimension includes the edges or "ears" that protrude from each side of the equipment, allowing the module to be fastened to the rack frame with screws or bolts. Common uses include computer servers, telecommunications equipment and networking hardware, audiovisual production gear, and scientific equipment. Overview and history Equipment designed to be placed in a rack is typically described as rack-mount, rack-mount instrument, a rack-mounted system, a rack-mount chassis, subrack, rack cabinet, rack-mountable, or occasionally simply shelf. The height of the electronic modules is also standardized as multiples of or one rack unit or U (less commonly RU). The industry-standard rack cabinet is 42U tall; however, 45U racks are also common. The term ''relay rack'' appeared first in the world of telephony. By 1911, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cabletron
Cabletron Systems was a manufacturer of networking computer equipment throughout the 1980s and 1990s primarily based in Rochester, New Hampshire, in the United States. They also had manufacturing facilities in Ironton, Ohio, and in Ireland. History Cabletron was founded in 1983 in a Massachusetts garage by Craig Benson (who later became Governor of New Hampshire, New Hampshire's governor) and Robert Levine. As manufacturing and design operations expanded, Cabletron relocated to Rochester, New Hampshire, employing 6,600 people at its peak. In 1996 the company eclipsed US$1 billion in sales. Cabletron found its first success in the 10BASE5 Ethernet market, providing the ST-500, the first Ethernet transceiver that featured diagnostic LEDs, and the LAN-MD, the first commercially viable field-deployable 10BASE5 test set. The early products were critical in the history of Ethernet as 10BASE5 Ethernet was generally difficult to operate and maintain and cabling problems were especially d ...
