The Atari 410 came in two variations, but both had identical specifications.  Atari cassette drives had a unique double-track feature, enabling sound and data to be recorded and transmitted.  This was used in such programs as the Atari language modules and Invitation to programming series, utilising a narrator while the program ran on screen.  The Atari 410 used the advanced Serial I/O interface (SIO), enabling easy connection to the computer.  Originally designed specifically for the 410, it was decided to use it on all Atari 8-Bit peripherals.

Atari's first disk drive product, the 810 provided fast and efficient storage and data retrieval for the new 8-Bit line of computers.  The unit is large (also including a disk-drive controller inside), but not unusually so for the time.  The single sided device enabled up to 88K of data storage on each side of a single 5.25" floppy disk.  Up to 4 810's could be daisy-chained via the SIO system.

The Atari 815 was Atari's first true double density disk drive.  It was also the largest drive system produced, and would only see a very limited commercial release.  Supporting two drive mechanisms, ach unit cost approx. $1,500.00!

A quick and easy solution to printing, the 820 plugged directly into a 400 or 800 via the SIO without the need for any drivers or printer controllers. It produced a 40 column output.  A typically  large device for the time, there was no mistaking the unit was working, as that's about all you could hear while it printed!

A small and versatile thermal printer, the 822 from Atari was very popular.  A 40 column printer with a retail price of Approx. $449.00

A rebranded Centronics 737, the Atari 822 was a small and competent 9-Pin dot-matrix 80 column printer.  Unlike its smaller brother, the 820, the 825 required the 850 interface for use with the Atari 400 or 800 computer because it uses the Centronics printer port, and not the Atari SIO system.

Atari's first modem product, this 300 baud unit was based on the commonly used "Acoustic coupler" design, whereby the phone receiver is physically placed inside the modem via 2 rubber holders, or couplers.  This unit required the 850 interface to communicate to the computer.

Although the 830 was functional, the acoustic coupler design had many flaws.  It wasn't long until a self-contained modem device was available, and the Atari version was the 835 direct connect modem.  Again, a 300 baud device, it was more efficient and didn't require the 850 interface.

The Atari 850 served as the middle-man for any device that couldn't directly connect to the Atari 400 or 800 computer.  It had 4 x serial ports (RS-232C) and 1 x Centronics (8-Bit Parallel) port.  Although a "must-have" product for any serious user, Atari decided to use the female DB-9 serial port and the female DB-15 Centronics ports on the 850.  Both ports chosen by Atari were not adopted as the industry standard, with the male DB-9 used for Serial and the male DB-25 Centronics used for Parallel, even to this day!

Probably the closest and most recognisable symbol next to the Fuji, the CX-40 became the standard choice for gamers in the late 70's and 80's.  With possibly over 30 million produced, the CX-40 was the first commercially successful joystick design, and you could even buy an officially made repair kit if you played too many hours of Star Raiders!

The Communicator - Came with Telelink One manual and program cartridge, 830 Modem and 850 Interface.

The Communicator II - with the direct connect 835 modem and Telelink II program cartridge.

The Programmer -with the basic programming guide, reference book and Atari Basic program cartridge.

The Home Manager - with Home Filing Manager, Family Finances and Timewise programs.

The Educator - with Atari 410 program recorder, Atari Basic and the States and Capital program on cassette.

The Entertainer - with 2 x CX-40 joysticks, Pac-Man, and the award winning Star Raiders game cartridges.

Pilot - Atari produced many fine programs for the 400 and 800 range of computers.  Many were geared for education, and among these were the Pilot series, which came in a full "Educator" package for the classroom, and a consumer version for the home.  Many of the earlier Atari programs were produced to an incredible high quality, with plastic binders, audio tapes and easy to read manuals and reference guides.
