Subject: 4.6) How can I use a Centronics or IBM parallel interface printer?
What is now known as IEEE 1284 originated as the "Parallel Interface Specification for Centronics Printers," a unidirectional 8 bit host-to-printer connection. This interface was introduced by Centronics Data Computer Corporation for a series of small serial-impact printers that began with
1970's Centronics Model 101. Centronics defined the interface timing and signals as well as the interface connector (at the printer), but not the host connector (at the computer). The Centronics parallel interface eventually became the primary interface used between most small computers and associated printers.
Even as Centronics themselves began utilizing alternative interface connectors on some of their own printers, the market success of 1980's Epson MX-80 helped the industry settle on Centronics' original choice of the 36-contact Amphenol 57-40360 (Micro-Ribbon brand) miniature-ribbon receptacle (female) as the standard interface connector found on parallel interface printers. The corresponding cable connector is the 36-contact Amphenol 57-30360 (Micro- Ribbon brand) miniature-ribbon plug (male). 36 contact miniature-ribbon connectors became known popularly as "Centronics" connectors; these are now known as the IEEE 1284-B Receptacle and Plug connectors.
IBM introduced the IBM PC in August 1981, with a Centronics-like Parallel Interface (with DB-25S connector), along with a series of Centronics-like parallel interface printers (with "Centronics" connector) starting with the
IBM PC Graphics Printer (model 5152, a slightly-modified Epson MX-80). The Parallel Interface as implemented by IBM was compatible with a functional subset of the existing Centronics standard, but more complete implementations of the IBM and Centronics interfaces were not signal-compatible, and a new category of the "IBM" compatible printer was established. Market success of the IBM PC meant wide adoption of the IBM parallel interface standard. This included the DB-25S host connector, which is now also known as the IEEE 1284-A Receptacle.
Industry implementations of the Centronics/IBM parallel interface continued to vary until the 1994 publication and subsequent wide adoption of IEEE 1284, "IEEE Standard Signaling Method for a Bidirectional Parallel Peripheral Interface for Personal Computers." The current version is IEEE 1284-2000.
The 8-bit Atari computer does not include a Centronics parallel output interface, but one may be added to the system. Atari provided the 850 Interface, and later the XEP80 Interface, for this purpose. Many 3rd-party interfaces and other devices provide compatible interfaces.
The following should be a complete list of devices for the Atari providing the system with a Centronics parallel printer host interface. Interfaces connect to the Atari via SIO unless otherwise specified, and are compatible with the Atari 850 Printer port unless otherwise specified. The interface connector type is given if known.

Subject: 5.1) What are the Atari 830, 835, 1030, XM301, and SX212 Modems?
Thanks to Laurent Delsarte for some of the research and writing for this section.
A modem (MOdulator-DEModulator) is a device that modulates an analog carrier signal to encode digital information for transmittal, and also demodulates
such a carrier signal to decode received transmitted information. The common example from the main time period of the 8-bit Atari computers is the voice band modem, otherwise known as a "dial-up modem" that turns the digital data
of a personal computer into modulated electrical signals in the voice
frequency range of a telephone channel. These signals can be transmitted over telephone lines and demodulated by another modem at the receiver side to recover the digital data. Thus, in this pre-Internet form of computer networking, any two computers may communicate with each other over a standard telephone line.
The first commercially successful modem was the Bell 103 from AT&T. While the AT&T Bell System maintained monopolistic control over the direct connection to its phone lines in the USA, third-party manufacturers could only offer "acoustic" modem configurations. Acoustic modems featured a cradle designed
to fit snugly around the microphone and earpiece of a standard (of the time) Bell telephone handset. A standard Bell telephone was utilized for it's microphone, speaker, and dialing capabilities. Such modems were designed to
be interoperable with the Bell 103, which maintained its role as the effective industry standard.
Later "direct-connect" modems, led by the Hayes Smartmodem, instead connected directly to the phone line. These modems contained their own microphones, speakers, and dialing capabilities controlled via software. The "Hayes
command set" successfully established the industry standard for controlling modem features via computer software.
Most voice band modems have a pass-through line allowing a standard telephone to be physically connected to the line while the modem is also connected. However, voice and data cannot be transmitted at the same time over the same phone line (as is possible with newer telecommunication technologies such as ISDN and DSL). When online using a dial-up modem, before telephone services like voice mail were common, incoming callers would experience a "busy signal" as if someone was already talking on the line. This limitation was finally addressed in 2001 with the V.92 modem standard. V.92 includes a "Modem On Hold" capability, especially useful in combination with the phone company's "call waiting" and "caller ID on call waiting" features.
A wide variety of modulation and communication techniques can be successfully implemented over a standard telephone line. In order for two modems to communicate, they have to initially successfully negotiate the technical
nature of the communications to be used between them. Connection characteristics include modulation technique ("frequency shift keying", "phase shift keying", etc.), operation mode (one-way "half duplex" or bi-directional "full duplex"), synchronization ("asynchronous" data without clock signal or "synchronous" data accompanied by separate clock signal), and bitrate
(measured in bits per second). Early modem users had to become familiar with arcane settings such as these in order to establish successful modem to modem communications. In time, modem modulation standards were established and adopted by the industry, allowing for the details to largely become
transparent to the user. Newer modems would simply negotiate the fastest and most reliable connection possible between them, given the best capabilities of both modems. Major modem modulation standards:
Standard (Year appeared) Top Bitrate Baud(symbols per second)
Bell 103 modem (1962) 300 bit/s 300 (V.21 precursor)
Bell 212A modem (1977) 1200 bit/s 600 (V.22 precursor)
V.22bis (1982) 2400 bit/s 600
V.32 (1986) 9600 bit/s 2400
V.32bis (1991) 14400 bit/s 2400
AT&T V.32ter (1993) 19200 bit/s 3200 ("terbo"; V.34 precursor)
Rockwell V.FC (1993) 28800 bit/s 3200 ("Fast Class"; V.34 precursor)
V.34 (1994) 28800 bit/s 3200
V.34 (1996) 33600 bit/s 3429 ("V.34 Plus" or "V.34bis")
US Robotics X2 (1997) 56000 bit/s 8000 (V.90 precursor)
Rockwell K56flex(1997) 56000 bit/s 8000 (V.90 precursor)
V.90 (1998) 56000 bit/s 8000
V.92 (2001) 56000 bit/s 8000
At the time, it was very common for modem speed bit rates to be incorrectly referred to as "baud" rates. Other than the early 300 bit/s / 300 baud modulation standard this was never correct usage of the term. Baud always meant "symbols per second" rather than "bits per second."
Two additional important modem standards emerged in 1990: V.42 error control and V.42bis data compression. V.42 and V.42bis were implemented in some later V.22bis and V.32 modems, and probably in all modems supporting V.32bis and up. V.92 modems, which appeared in 2001, support V.44 data compression, an improvement over V.42bis compression.
In the early 1980s popular early commercial online services reached via dial- up modem included CompuServe Information Service, Dow Jones Information Service, and The Source. In addition to CompuServe, later online services popular with Atari users included Delphi and GEnie. Modem users would also dial in to mainframe computer systems at universities, or they would log in to privately-operated Bulletin Board Systems running on other personal computers. As long-distance telephone services were billed by the minute, telephone bill expenses were an important consideration.
Atari produced several modems for use with the 8-bit Atari computers. Each Atari brand modem supports U.S. modulation communication standards only; Atari did not market their modems in Europe.
