Notes The Atari 800 was a very advanced machine for its time. Although it was built around the same microprocessor as many of its direct competitors such as the Apple II Plus and the Commodore Pet it added various co-processors to handle graphics and sound generation tasks.
Related Items in Collection 810 disk drives, 1050 disk drive, other Atari 800 systems, software and cartridges, Atari 400
Related Items Wanted Additional disk drives (810, 1050, RANA), cartridges and software. 850 interface, Atari brand joysticks.

Atari started out as a game maker. Nolen Bushnell, Atari's founder, invented pong and created Atari to bring it to market in the early 1970s. By the end of the decade they decided to release a computer system to compete with Apple and the rest of the "home" computer market. In 1979, the Atari 400 and Atari 800 were born to fulfill this promise. Since they were Atari products, they were supremely strong graphical performers.

The Atari 800 in my collection is a 48K unit with a tape drive and an 810 disk drive (pictured below). I have several Atari cartridges and most of the original manuals for the machine as well.

The Atari 810 5.25 inch disk drive

Mike Newhall was nice enough to write in with some corrections (I swear I'm going to set up a comment system someday!)

"Processor Motorola 6502"

The 6502 was a Rockwell design, licensed to various parties (including Commodore). But I don't believe Motorola ever made them. They had a competing series, the 6303/6305/6309, that were used for example in the Radio Shack Color Computer.

"Speed 1 MHz"

The speed was exactly half the TV color clock signal, which for NTSC works out to 1.79 MHz, almost twice as fast as the C64.

"RAM Up to 48K"

True for the 'official' specs of the 800. I have one with 288K using 3rd party mods. Atari later made the 800XL w/64K, the 130XE with 128K, and there were 3rd party mods for up to a megabyte of RAM.

"Video Up to 320x192x16"

The 320x192 mode was really "one and a half" colors - the background was one color while the foreground was a different brightness of the same hue. Special "GTIA" modes added to later 800's allowed up to 16 shades of one hue, 16 hues of one shade, or 9 independent colors in 80x192. The highest-rez mode with normal-shaped pixels and normal color behavior was 160x192x4. So there was no true "x16" mode.

But the graphics hardware was extremely flexible - in the vertical dimention. One could change the color palette on every scan line, and even change the number of displayed scan lines, so it was easy to get all 256 colors on screen at once, in resolutions of NNNx200 to NNNx224 or even more. You were just limited to how many colors you could get on a single horizontal line.

All great info! Thanks! Appropriate corrections have been made in the table at the top of the page.

Just before I went into high school in 1985, I bought an atart600xl computer and a 1010 Tape drive and a bunch of game carts, this whole system probably set me back $1000.00. I am married now and have kids, and a couple years ago I found an Atari 600XL on ebay along with an Atari disk drive for $45.00 so I bought it and added some game carts to boot. Yesterday I ran across an 800XL with 64K memory for $35.00. I bought it, and I cant wait to get it. Brings back so many memories!!

As Atari diskette drives were very expensive (15x cassette recorder) and practically inavailable in former Czechoslovakia (during communist era), a czech-specific modification to Atari cassette recorder called Turbo was invented, that increased read/write speed from original 600 Bd to 2270 Bd (expanding cassette capacity appropriately). This was a home-made printed circuit that bypassed original modulation and added one wire (typically twisted around original data cable) + simple software driver. Later, more precise (3630 Bd and variable speed) variants appeared. Almost every local Atari owner had it.

My neighbor had this and we played a game called Galaxy. Not to be confused with the video game galaxy. This had to be loaded from a cassette tape and you could have about 10 players and up to 20 turns (years). We'd have Galaxay parties that would last 4 of 5 hours. Some great times. Food, Beer Music and Galaxy. Each person would input their moves and then after each player did this you'd run the data and see the results. Some players moves you wouldn't know the resultst of until later because they might have taken years (turns) to complete You'd take over worlds in the galaxy and thenhave to defend them from being taken over by other players. Great fun basic startegy game.

It was a load of fun when we'd have parties like this at someone's home, especially after football season was over with.

I have two Atari systems (one is the 800 with floppy drive and the other is a 1600 with floppy drive.) My problem is that it's been years since I've used either system (20 years since I used the 1600 and probably 25 years since I used the 800.) That said, I'm having a hard time remembering how to set it up for use. I know that both systems worked just fine before they went into storage. Does anyone have any information that might help me get the systems up and running again? I still have tons of old floppies that I'd love to play (assuming that they haven't gone corrupt over time.) Thanks!

The processor was not a Rockwell 6502; rather it was a MOS 6502 ... the same 8-bit processor in the Commodore PET and the Apple II and fore- runner of the MOS 6510 used in the Commodore 64.

RE: the 'competing chips' from Motorola; the 6803 was used in the TRS-80 MC-10 while the 6809 was used in the CoCo. Hitachi made the 6309, which is compatible with the 6809, but, when run in native mode has many enhanced features the Motorola chip does not have.. The 6805 was never used in any of the CoCo line.

RE: 6502 / MOS / Rockwell, AMD also made their beginnings producing 2nd source chips for 6502 and it's various replacements the 6502A, 6502B and 65C02. MOS made a mistake changing the pinout of the 65C02 so that it required re- engineering the circuitry, rather then just dropping it in.

The ONLY edge tramiel gave commodore's C64 series that atari didn't and should have included was the SID chip, the famous multichannel sound processor.

there was an aftermarket mod available to add a SID to the Atari but it came after Commodore bought MOD and stopped selling the SID chip as a part, so supplies of the SID chip dried up and the upgrade fizzled.

I was a member of the famous High Tech Team (europe demo coders) for the atari 8bit system. We made several demo programs (big demo). I was also involved in a project by using the 65816 in an atari 130Xe system. But it was a bit diffult to program. I programmed several programs, and moved on to the Amiga and then PC scene later on. Good times on the atari 8bit. Best game i ever bought was Gauntlet for 39 dutch guilders in the 80s. Yeah, 2 tapes , and a very good game. Later on, we also swaped demo disks with polish friends and people from the usa and other countries. We also had in holland local atari clubs (even in the 90s!!!) , only 8bit atari, not ST or such. We programmed our own games, had local distribution channels made alive, had schools for education and many things more. Not much support from atari benelux, but yeah, we got free t-shirts and some goodies like an original atari rainbow flag, from Atari Benelux.

I had an 800 and I loved it. It was my second omputer (my first computer was a VIC 20). Some of my favorite games were BLUE MAX, Choplifter, Claim Jumper and THORN EMI's Submarine Commander and a PAC MAN type game called Jawbreaker which was great. I loved programming the 800 too with all the different graphics modes.

I picked up an 800, with the floppy drive. numeric keypad, modem, and all the appropriate cables at a yard sale for $10. It came with 10 games, still in the original boxes, and the Atari word processor software. This is a complete setup with all the hookups, and it works perfectly. Is there a website out there where i could sell it to someone that would appreciate it? I would only like to get $35-$40 for it, but I would like it to go to a good home. It has EVERYTHING that you could have bought for it and its in perfect shape. Interested? Drop me an E-Mail.

Back in the 80's when these were sold at KMart, we (some of the computer science students at a small community college) would pull a little prank on the sales people at kmart. a couple of us would keep the sales people busy, while another would type in the commands on the display model that set all the colors to the same value. The one of the guys with a sales person would ask to see the atari computer. The sales people had no computer background and couldn't figure out why the computerwasn't working. (actually it was working, but the text was invisible on the screen. We had similar trick to the Commodore 64, Tandy Color computer, and TI 99/4

I got my 800 back in 1982 just before they went to the 800XL. My first disk drive was the Indus drive. I used the cassette drive for quite a few years. I then got the Indus and then an ATR8000 plus two 5 1/4 drives from an old IBM. I also got a 3 1/2 drive. When I quite using the Atari was about 1995. At the time I had an 130XE with 320k memory plus a Black Box with a 320meg hard drive. I sold the ATR8000 but used the drives with the Black Box. I bought a device from a guy in California that let me connect an IBM keyboard to the Atari. When I think back at the money I spent on that Atari. I still have great memories of those times. The money spent was worth it for the moemories.

I worked at Datasoft during the early 80's - Datasoft published games on tape and disk for the Atari, Apple ][ , C64 & Tandy Color Computers. I personally worked on MoonShuttle and juno first and parts of zaxxon (A800). I wrote most of the loaders and software protection code in 6502 assembly language. All of the games were written in 6502 assembly.

For their time, the Atari and C64 were advanced machines.

The 800 was my first computer which I still have sitting in a box along with its 5.25 floppy drive and cassette recorder. I used to program this pc and play games on it in my youth. I even did a paper on the 6502 chip in my college years.

There seems to be some confusion about the 6502. Recommend people read the articles about it on Wikipedia.

In short. Rockwell manufactored the 6502, but did not design it. The 6502 was designed by MOS Technology, which was founded by former Motorola employees, hence the design similiarities to the 6800 chip. At this time, it was important the chips be available from other sources (known as 'second sources'). Companies would not buy your chip unless there were second sources. Rockwell was a second source for 6502.

MOS was lated taken over by Commodore. This is because Commodore was using their chips in their computers (6502, 6510, etc).

The design for the 6502 would be licensed to Western Digital Design (another second sourcer), who would later create the 65816, the 8/16bit version of the 6502 used in the Apple IIgs.

I didn't own an Atari 800, or a C64, but a 48K Apple II+. Anyways, the 6502 was never designed by Rockwell whatsoever. The 6502 was designed by MOS technology, and later on, around 79-80, MOS licensed the 6502 design to different chip manufacturers, including Rockwell. And MOS Technology was owned by Commodore.

Hey, where's the Atari 1200XL? I have one with an 850 interface and disk drive. I used to get on the internet with it in the eighties when all you had to do was go to a local BBS and get a number (usually long distance). There was no graphical interface! I must say, it was a challenge, but workable.

There were a few additional Atari machines, the 1200 and the 1400 as I remember. Quite a bit smaller and sleeker than the 800 but about the same capability, I think.

I remember MANY days spent playing games like dig dug, and the infamous ZORK series!!!

The atari 800 was not only designed to be a powerful computer, but it was also designed to be a serious gaming machine! In fact, most programs for the atari 8-Bits where games!

The Atari 800 could have Its RAM upgraded very easly. You just had to open the cartridge bay & in the back, you could see 2 twisty- thingies (later replaced by screws). After that you just had to pull off the front cover & then you had access to the OS & RAM slots. After that you just had to plug in a new RAM upgrade modules and then you where set!

The competing motorola processors you refer to are the 68xx series of processors. Most noteably the 6809 used in the Radio Shack Coco computers. Hitachi later on made a CMOS replacement for the 6809 called the 6309 that ran faster. A lot of Coco users later switched to this processor.
