    Subject: 1.4) What is the Atari 1200XL?

    Introduced in December 1982 and shipped in March 1983, the Atari 1200XL was designed to replace the Atari 800 while maintaining compatibility with the earlier model.

    The project that led to the introduction of the 1200XL had been known inside Atari by names including: "Z800", "Sweet-16" / "S-16", "1000X", "1200X"

    Innovations relative to the 400/800 include a full 64KiB of RAM and a significantly revised XL Operating System (ROM expanded from 10KiB to 16KiB).

    The 1200XL is the only 8-bit Atari computer to feature two LED indicator
    lights (L1, L2). Normally they are both <OFF>. L1 <ON> means the keyboard is disabled. L2 <ON> means the new International Character Set is selected.

    Keyboard enhancements introduced with the 1200XL include the new [HELP] key as well as four programmable functions keys ([F1], [F2], [F3], [F4]). Console Speaker sounds (keyclicks and system beeps) output through the built-in
    speaker on the 400/800 are heard from the television or monitor speaker on the 1200XL. The toggle action of the [CAPS] key was altered compared to the 400/800. The key auto-repeat rate is user-alterable. The [RESET] key is directly wired to the SALLY 6502 reset line.

    1200XL Function key effects, redefinable:
    [F1] Cursor up [SHIFT]+[F1] Cursor to upper-left corner (home)
    [F2] Cursor down [SHIFT]+[F2] Cursor to lower-left corner
    [F3] Cursor left [SHIFT]+[F3] Cursor to start of physical line
    [F4] Cursor right [SHIFT]+[F4] Cursor to end of physical line

    1200XL Function key effects, non-redefinable:
    [CONTROL]+[F1] Keyboard enable/disable (console keys unaffected)
    [CONTROL]+[F2] Screen DMA (ANTIC) enable/disable
    [CONTROL]+[F3] Key click sound enable/disable
    [CONTROL]+[F4] Domestic/International character set toggle

    Additional 1200XL Operating System enhancements compared to the 400/800 OS:
    - Self Test program
    - Text screen fine scrolling is available
    - The Resident Diskette Handler can read/write disk sectors having variable
    length from 1 to 65536 bytes.
    Default = 128 bytes (matching the 400/800 static value)
    - The Resident Diskette Handler can write a sector to the disk without a
    read-verify operation always following it.
    - Universal OS for both NTSC and PAL systems (including independent values
    for cassette timings and for keyboard auto-repeat functions)

    A few features from the 400/800 are lacking in the 1200XL. Most prominently, the 1200XL has only 2 controller ports, and no Memo Pad / Blackboard mode.

    With the 1200XL Atari made an apparent decision to preclude peripherals from drawing their power from the computer via the SIO bus:
    - The 1200XL lacks +12V on SIO pin 12, as was available on the 400/800.
    - On the 1200XL the +5V/Ready line (pin 10) on the SIO port supplies enough
    current for the Ready ("Computer On") function but not enough current for
    peripherals designed to use the line as their power source.
    ("FIX": Replace 100 Ohm resistor R63 with a 0 Ohm to 1 Ohm resistor, or a
    jumper wire.)

    The labels on several of the 1200XL keyboard keys differ slightly from those
    of the 400/800: 400/800 1200XL
    [CTRL] --> [CONTROL]
    [SYSTEM RESET] --> [RESET]
    [CAPS LOWR] --> [CAPS]
    [DELETE BACK S] --> [DELETE BACK SPACE]
    "Atari logo" key --> "Inverse video" key

    System initialization types supported:
    - "ATARI" rainbow logo/graphics demo screen: Turn on computer with no
    cartridge inserted and no powered disk drive #1.
    - Press [HELP] from the "ATARI" logo screen to access Self Test program.
    - Cartridge: Turn on computer with cartridge inserted.
    - Cassette boot: (boot cassette may or may not require cartridge inserted)
    1. Hold down [START] while turning on the computer. (system buzzer sounds)
    2. Press [PLAY] on the program recorder with boot cassette inserted.
    3. Press [RETURN] on the computer.
    - Disk boot: (boot disk may or may not require cartridge inserted)
    Turn on computer with boot disk inserted in powered disk drive #1.

    Scott Stilphen mentioned this 1200XL easter egg on 10 Feb 2006:
    On 1200XLs, if you select 'all tests', when it gets to the keyboard test
    it'll type out the programmer's name.

    The 1200XL was manufactured at Atari's plant at 1215 Borregas, Sunnyvale CA from January 1983 to May 1983, and was also made by Atari Taiwan Manufacturing Corp. from April 1983 to July 1983. Serial numbers: http://atariage.com/forums/topic/107234-1200xl-owners-club-serial-tracker/

    Subject: 1.5) What is the Atari 600XL?

    Introduced in June 1983 alongside the 800XL, 1400XL (never shipped), and 1450XLD (never shipped), and shipped that fall, the Atari 600XL was designed
    to replace the Atari 400 while maintaining compatibility with the earlier model.

    The project that led to the introduction of the 600XL had been known inside Atari by names including: "600", "Liz", "Crazy 8", "S-8" / "Sweet-8", "Surely"

    The 600XL/800XL include most of the features of the 1200XL, minus the 4 Function keys, the 2 LED lights, and the "ATARI" logo screen. But both the 600XL and 800XL have the Atari BASIC language built-in. In addition, these
    two systems offer the Parallel Bus Interface (PBI), providing fast parallel access to the heart of the computer.

    Available current on the +5V/Ready line (pin 10) on the SIO port of the 600XL/800XL matches that on the 400/800, restoring compatibility with SIO peripherals designed to draw power from that line which would not work on the 1200XL.

    The 600XL contains 16KiB RAM. The Atari 1064 Memory Module expands the 600XL from 16KiB to 64KiB RAM.

    System initialization types supported:
    - Atari BASIC: Turn on computer with no cartridge inserted and no powered
    disk drive #1.
    - Self Test program: Hold down [OPTION] while turning on the computer with no
    cartridge inserted and no powered disk drive #1.
    - Cartridge: Turn on computer with cartridge inserted. (disables BASIC)
    - Cassette boot: (boot cassette may or may not require BASIC or cartridge)
    1. - With BASIC or with cartridge (cartridge disables BASIC):
    Hold down [START] while turning on the computer.
    - With no cartridge and without BASIC:
    Hold down both [START] and [OPTION] while turning on the computer.
    (system buzzer sounds)
    2. Press [PLAY] on the program recorder with boot cassette inserted.
    3. Press [RETURN] on the computer.
    - Disk boot: (boot disk may or may not require BASIC or cartridge inserted)
    - With BASIC or with cartridge (cartridge disables BASIC):
    Turn on computer with boot disk inserted in powered disk drive #1.
    - With no cartridge and without BASIC:
    Hold down [OPTION] while turning on computer with boot disk inserted
    in powered disk drive #1.

    Subject: 1.6) What is the Atari 800XL?

    Introduced in June 1983 alongside the 600XL, 1400XL (never shipped), and 1450XLD (never shipped), and first shipped late that year, the Atari 800XL was designed as the 64KiB RAM version of the low-end 600XL. Small quantities of 800XL computers shipped in the U.S. late in 1983, before mass shipments commenced worldwide late winter/early spring, 1984.

    The project that led to the introduction of the 800XL had been known inside Atari by names including: "600", "Liz", "Crazy 8", "S-8" / "Sweet-8",
    "Surely Plus"

    The 600XL/800XL include most of the features of the 1200XL, minus the 4 Function keys, the 2 LED lights, and the "ATARI" logo screen. But both the 600XL and 800XL have the Atari BASIC language built-in. In addition, these
    two systems offer the Parallel Bus Interface (PBI), providing fast parallel access to the heart of the computer.

    Available current on the +5V/Ready line (pin 10) on the SIO port of the 600XL/800XL matches that on the 400/800, restoring compatibility with SIO peripherals designed to draw power from that line which would not work on the 1200XL.

    Subject: 1.7) What is the Atari 65XE?

    Introduced in January 1985 alongside the 130XE, the Atari 65XE was the low-end machine in the new range of XE computers that would replace the Atari 600XL/800XL while maintaining compatibility with the earlier models.

    The 65XE does not include the PBI port as on the 600XL/800XL, but many 65XE machines include the similar (though physically incompatible) Enhanced Cartridge Interface (ECI).

    The 65XE offers 64KiB RAM, and has the Atari XL OS and Atari BASIC on ROM.

    While 1200XL/600XL/800XL keyboard key labels used capital letters exclusively, on 65XE/130XE keyboards only the first letter of the word is capitalized.
    Also, the [DELETE BACK SPACE] key from the 1200XL/600XL/800XL is labeled [Delete Bk Sp] on the 65XE/130XE.

    System initialization types supported:
    - Atari BASIC: Turn on computer with no cartridge inserted and no powered
    disk drive #1.

    Subject: 1.9) What is the Atari XE game system?

    With the February 1987 introduction of the Atari XE game system, Atari both extended the established 65XE/130XE product line and also added a third game system to complement the established 2600 and 7800 product lines.

    Termed variously by Atari as the XE Video Game System, the XE Game System, or the XE System, the name was actually trademarked by Atari as simply: XE.
    (For clarity, this FAQ List will normally use "XE game system" or "XEgs".)

    The core component of the XEgs is the XE System Console, which is essentially
    a complete 65XE/800XE but without a keyboard. A companion XE System Keyboard was produced and often sold with the Console.

    The XE System Console offers 64KiB RAM, and has the Atari XL OS Rev.4 (16KiB),

    Subject: 1.4) What is the Atari 1200XL?

    Introduced in December 1982 and shipped in March 1983, the Atari 1200XL was designed to replace the Atari 800 while maintaining compatibility with the earlier model.

    The project that led to the introduction of the 1200XL had been known inside Atari by names including: "Z800", "Sweet-16" / "S-16", "1000X", "1200X"

    Innovations relative to the 400/800 include a full 64KiB of RAM (62KiB usable) and a significantly revised XL Operating System (ROM expanded from 10KiB to 16KiB).

    The 1200XL is the only 8-bit Atari computer to feature two LED indicator
    lights (L1, L2). Normally they are both <OFF>. L1 <ON> means the keyboard is disabled. L2 <ON> means the new International Character Set is selected.

    Keyboard enhancements introduced with the 1200XL include the new [HELP] key as well as four programmable functions keys ([F1], [F2], [F3], [F4]). Console Speaker sounds (keyclicks and system beeps) output through the built-in
    speaker on the 400/800 are heard from the television or monitor speaker on the 1200XL. The toggle action of the [CAPS] key was altered compared to the 400/800. The key auto-repeat rate is user-alterable. The [RESET] key is directly wired to the SALLY 6502 reset line.

    1200XL Function key effects, redefinable:
    [F1] Cursor up [SHIFT]+[F1] Cursor to upper-left corner (home)
    [F2] Cursor down [SHIFT]+[F2] Cursor to lower-left corner
    [F3] Cursor left [SHIFT]+[F3] Cursor to start of physical line
    [F4] Cursor right [SHIFT]+[F4] Cursor to end of physical line

    1200XL Function key effects, non-redefinable:
    [CONTROL]+[F1] Keyboard enable/disable (console keys unaffected)
    [CONTROL]+[F2] Screen DMA (ANTIC) enable/disable
    [CONTROL]+[F3] Key click sound enable/disable
    [CONTROL]+[F4] Domestic/International character set toggle

    Additional 1200XL Operating System enhancements compared to the 400/800 OS:
    - Self Test program
    - Text screen fine scrolling is available
    - The Resident Diskette Handler can read/write disk sectors having variable
    length from 1 to 65536 bytes.
    Default = 128 bytes (matching the 400/800 static value)
    - The Resident Diskette Handler can write a sector to the disk without a
    read-verify operation always following it.
    - Universal OS for both NTSC and PAL systems (including independent values
    for cassette timings and for keyboard auto-repeat functions)

    A few features from the 400/800 are lacking in the 1200XL. Most prominently, the 1200XL has only 2 controller ports, and no Memo Pad / Blackboard mode.

    With the 1200XL Atari made an apparent decision to preclude peripherals from drawing their power from the computer via the SIO bus:
    - The 1200XL lacks +12V on SIO pin 12, as was available on the 400/800.
    - On the 1200XL the +5V/Ready line (pin 10) on the SIO port supplies enough
    current for the Ready ("Computer On") function but not enough current for
    peripherals designed to use the line as their power source.
    ("FIX": Replace 100 Ohm resistor R63 with a 0 Ohm to 1 Ohm resistor, or a
    jumper wire.)

    The labels on several of the 1200XL keyboard keys differ slightly from those
    of the 400/800: 400/800 1200XL
    [CTRL] --> [CONTROL]
    [SYSTEM RESET] --> [RESET]
    [CAPS LOWR] --> [CAPS]
    [DELETE BACK S] --> [DELETE BACK SPACE]
    "Atari logo" key --> "Inverse video" key

    System initialization types supported:
    - "ATARI" rainbow logo/graphics demo screen: Turn on computer with no
    cartridge inserted and no powered disk drive #1.
    - Press [HELP] from the "ATARI" logo screen to access Self Test program.
    - Cartridge: Turn on computer with cartridge inserted.
    - Cassette boot: (boot cassette may or may not require cartridge inserted)
    1. Hold down [START] while turning on the computer. (system buzzer sounds)
    2. Press [PLAY] on the program recorder with boot cassette inserted.
    3. Press [RETURN] on the computer.
    - Disk boot: (boot disk may or may not require cartridge inserted)
    Turn on computer with boot disk inserted in powered disk drive #1.

    On 1200XLs, if you select 'all tests', when it gets to the keyboard test
    it'll type out the programmer's name.

    Subject: 1.5) What is the Atari 600XL?

    Introduced in June 1983 alongside the 800XL, 1400XL (never shipped), and 1450XLD (never shipped), and shipped that fall, the Atari 600XL was designed
    to replace the Atari 400 while maintaining compatibility with the earlier model.

    The project that led to the introduction of the 600XL had been known inside Atari by names including: "600", "Liz", "Crazy 8", "S-8" / "Sweet-8", "Surely"

    The 600XL/800XL include most of the features of the 1200XL, minus the 4 Function keys, the 2 LED lights, and the "ATARI" logo screen. But both the 600XL and 800XL have the Atari BASIC language built-in. In addition, these
    two systems offer the Parallel Bus Interface (PBI), providing fast parallel access to the heart of the computer.

    Available current on the +5V/Ready line (pin 10) on the SIO port of the 600XL/800XL matches that on the 400/800, restoring compatibility with SIO peripherals designed to draw power from that line which would not work on the 1200XL.

    The 600XL contains 16KiB RAM. The Atari 1064 Memory Module expands the 600XL from 16KiB to 64KiB RAM (62KiB usable).

    System initialization types supported:
    - Atari BASIC: Turn on computer with no cartridge inserted and no powered
    disk drive #1.
    - Self Test program: Hold down [OPTION] while turning on the computer with no
    cartridge inserted and no powered disk drive #1.

    The 600XL was made by Chelco Sound (Hong Kong) Limited from July to December 1983 (NTSC units with "black label" 7YJ serial numbers), by Atari-Wong Co. in Hong Kong from September 1983 to April 1984 (most NTSC and all PAL units), and by Atari Taiwan Manufacturing Corp. (ATMC) from July to September 1984 (NTSC units). There were also some units assembled at ATMC in July 1985 (NTSC), apparently factory-refurbished from stock originally manufactured earlier.

    The Atari 600XL was utilized by Exidy as an embedded system in their
    Max-A-Flex coin-operated arcade conversion system (configurable to play:
    Astro Chase, Boulder Dash, Bristles, or Flip and Flop).

    Subject: 1.6) What is the Atari 800XL?

    Introduced in June 1983 alongside the 600XL, 1400XL (never shipped), and 1450XLD (never shipped), and first shipped late that year, the Atari 800XL was designed as the 64KiB RAM (62KiB usable) version of the low-end 600XL. Small quantities of 800XL computers shipped in the U.S. late in 1983, before mass shipments commenced worldwide late winter/early spring, 1984.

    The project that led to the introduction of the 800XL had been known inside Atari by names including: "600", "Liz", "Crazy 8", "S-8" / "Sweet-8",
    "Surely Plus"

    The 600XL/800XL include most of the features of the 1200XL, minus the 4 Function keys, the 2 LED lights, and the "ATARI" logo screen. But both the 600XL and 800XL have the Atari BASIC language built-in. In addition, these
    two systems offer the Parallel Bus Interface (PBI), providing fast parallel access to the heart of the computer.

    Available current on the +5V/Ready line (pin 10) on the SIO port of the 600XL/800XL matches that on the 400/800, restoring compatibility with SIO peripherals designed to draw power from that line which would not work on the 1200XL.

    System initialization types supported:

    Subject: 1.9) What is the Atari XE game system?

    With the February 1987 introduction of the Atari XE game system, Atari both extended the established 65XE/130XE product line and also added a third game system to complement the established 2600 and 7800 product lines.

    Termed variously by Atari as the XE Video Game System, the XE Game System, or the XE System, the name was actually trademarked by Atari as simply: XE.
    (For clarity, this FAQ List will normally use "XE game system" or "XEgs".)

    The core component of the XEgs is the XE System Console, which is essentially
    a complete 65XE/800XE but without a keyboard. A companion XE System Keyboard was produced and often sold with the Console.

    The XE System Console offers 64KiB RAM (62KiB usable), and has the Atari XL OS Rev.4 (16KiB), Atari BASIC Rev. C (8KiB), and Missile Command (8KiB) all built-in on ROM (all on a single 32KiB ROM chip), C101687.

    Distinctive hardware features of the XE System Console:
    - Keyboard Port (for the separate XE System Keyboard)
    - Audio jack (phono)
