Atari 8-bit computer peripherals

Atari 8-bit computer peripherals

This article covers the range of peripherals available for Atari's 8-bit home computer range (including the 400/800, XL and XE series machines).

All of Atari's external peripherals used the proprietary SIO port, which allowed them to be daisy chained together into a single string; a method also used in Commodore's home computers from the VIC-20 onwards. These "intelligent" peripherals were more expensive than the standard IBM PC devices, which did not need the added SIO electronics.

List of peripherals

Both the names and styling of Atari's 8-bit peripherals generally matched the current computer range at the time they were released. Thus, they can be divided into one of three groups- those corresponding to the 400/800 era (4xx/8xx), the XL era (10xx) and the XE era (beginning with 'X') respectively. (The XL-era naming reflected Atari's original intention to launch an "Atari 1000" line.) [http://www.landley.net/history/mirror/atari/museum/sweet16.html The Atari Sweet-16 Project] , landley.net. Article retrieved 2007-03-18.] Nevertheless, it should be emphasised that these are superficial issues; the majority of peripherals listed here will work with any 8-bit Atari computer.

In addition to those listed below, Atari failed to release a huge selection of machines and peripherals that were otherwise completed. (See the externally linked FAQ below for details.)

400/800 era (1979-1982)

*410 tape drive, 600 bit/s on cassettes
*810 5¼" floppy disk, single-density single-sided, 90 KB
*815 dual 5¼" floppy disks, double-density single-sided, 180 KB (only small numbers produced)
*820 printer, 40-column dot matrix on adding machine paper
*822 printer, 40-column thermal on slightly wider paper
*825 printer, 80-column dot matrix (Centronics 737)
*830 300-baud modem, using an acoustic coupler, used RS-232 so required an 850 (relabeled Novation CAT)
*835 300-baud modem, direct connect, basic Hayes compatible with SIO interface
*850 expansion system, included four RS-232 ports and one Centronics parallel port
*CX-85 Numerical Keypad, external keypad that plugs into the joystick ports.

The 410 tape drive used stereo with the data recorded on one track and the other track fed through the sound, as was demonstrated by the language courses. The tape could also be programmatically stopped and started, while 'played'.

XL era (1982-1985)

*1010 tape drive, a smaller replacement for the 410
*1020 color printer, 40-column plotter with 4 pens
*1025 printer, 80-column dot matrix (Okidata ML-80)
*1027 printer, 80-column letter quality that printed with a 5-wheels-on-a-drum system kept inked by a top-mounted roller (Mannesmann Tally Riteman LQ)
*1029 printer, 80-column lower-quality 7-pin dot matrix sold in Europe (Seikosha mechanism)
*1030 300 baud modem, direct connect
*1050 5¼" floppy disk, "enhanced density" format single-sided, 130 KB
*1055 3½" floppy drive (never released) [http://www.backntime.net/Atari%20Computers/8bit/Prototype/Frame8bitProto.html]
*1064 memory module, 64 KB memory expansion for 600XL
*CX77 touch tablet

XE era (1985 onwards)

*XEP80 80-column display module, based on NS405 chip (attached via a joystick port controlled by MOS Technology 6551)
*XC11 tape drive
*XC12 tape drive (small model like the 1010, sold worldwide). Similar models were released, mainly in Eastern Europe.

Version used last updated 2006-11-07, accessed 2006-11-08.] These included:-
**XCA12 (same case as XC12)
**CA12 (same case as XC12)
**XL12 tape drive (an XC12 with minor changes)
**XC13 - "T2000 ready" version of XC12
*XF351 3½" floppy drive (never released) [http://www.backntime.net/Atari%20Computers/8bit/Prototype/Frame8bitProto.html]
*XF551 5¼" floppy disk, double-density double-sided, 360 KB
*XMM801 printer, 80-column dot matrix
*XDM121 printer, 80-column letter quality daisy wheel
*XM301 300 baud modem
*SX212 1200 baud modem (also included RS-232 for use on Atari ST computers)
