    in that drive. As long as you follow that rule, you can utilize the
    backward compatible 360KiB modes that most 1200KiB drives offer. ===============================================================

    AnaDisk + DeAna
    ===============
    While the above mentioned utilities work with SS/DD 180KiB Atari-format disks or SS/DD 180KiB SpartaDOS disks, the following combination of utilities has been used successfully to read SS/SD 90KiB Atari-format disks. So if you only have standard Atari 810 and/or Atari 1050 drives, you could look into:

    AnaDisk, created by Chuck Guzis at Sydex, Inc. in 1987
    - "Scan, edit, repair and copy just about any kind of diskette"
    - Version 2.01, November, 1989
    - One source for AnaDisk 2.06 (1992):
    http://www.retroarchive.org/cpm/cdrom/UTILS/22DISK/ANAD206.ZIP
    - Some have reported more luck with this than 2.07
    - One source for AnaDisk 2.07 26-Aug-92:
    http://www.retrocomputing.org/cgi-bin/sitewise.pl?act=det&p=776&id=retroorg
    - Last free version, readily available, but sometimes described as buggy
    - Sold to New Technologies Inc. (NTI) by Sydex in March 2000.
    - More information: http://www.retrotechnology.com/herbs_stuff/sydex.html

    DeAna by Nate Monson

    - Converts AnaDisk dump files from Atari format

    See http://preview.tinyurl.com/kpnqcjp for tips on using this combination of utilities.

    OmniFlop (as of 2007)
    ========
    - By Sherlock Consulting (Jason Watton)
    - A 'universal' floppy disk reader, writer, and tester for the IBM PC or
    compatible which can handle alien floppy disk formats not normally
    supported by DOS, Windows and Linux.
    - OmniFlop on its own transfers disks between systems. If you want to access
    files, for example, on these disks then you need more - you will need to
    use OmniFlop to image the disk, then other software to interpret the
    filing system. OmniFlop alone only handles whole disks.
    - Features include, as of 2nd Sep 2007 v2.01m Release:
    - Read, write, and format Atari 8-bit format (90KiB). (Charles Doty)
    - Available: http://www.shlock.co.uk/

    ===============================================================
    The following more recent solutions involve connecting a standard "internal"
    PC floppy disk drive to a modern personal computer via USB port.

    KyroFlux (2009)
    ========
    - By KryoFlux Products & Services Limited
    - A USB-based floppy controller "designed specifically for reliability,
    precision, and getting low-level reads suitable for software preservation"
    - Compatible with USB 2.0 (high-speed).
    - Shugart (with extensions) drive interface. 34-pin dual-row header
    connector.
    - Works with all major 3.5" and 5.25" drives

    - Plugs into any computer's USB port and enables you to read data
    from a 5.25" floppy drive.
    - Sold as a controller board only without a drive mechanism.
    It has been tested to work well with the TEAC FD-55GFR drive and should
    also work with most other 5.25" drives.
    - The FC5025 is read-only. It cannot write to floppies.
    - The FC5025 may be unable to read disks that are damaged or copy-protected.
    - The FC5025 is intended for 5.25" disks only, not 3.5" or 8" disks.
    - The FC5025 may be unable to read the second side of "flippy" disks,
    depending on the drive it is attached to.
    - The included software works on: Linux, Mac OS X, Windows
    - The included software supports types of disk including: Atari 810

    Subject: 10.2) How can my other computer utilize my Atari disk drive?

    1050-2-PC function of SIO2PC 4.x, by Nick Kennedy
    Allows a PC to communicate directly with an Atari disk drive. Requires "1050-2-PC" cable which is very similar to the SIO2PC cable but configured differently. Software allows direct sector I/O with the Atari drive and can
    be used to create disk images which will emulate copy protection schemes when run on SIO2PC. Supports the .ATR disk image format.
    More 1050-2-PC information: http://pages.suddenlink.net/wa5bdu/1050.txt

    APE ProSystem, by Steven Tucker
    - The ProSystem hardware is a cable designed to allow connection of a stock
    1050 disk drive directly to a PC's serial port for use by the companion
    ProSystem software. Latest version:
    Atarimax Universal SIO2PC/ProSystem interface, USB or RS-232/Serial versions
    http://www.atarimax.com/sio2pc/documentation/
    - The ProSystem software program is used to create (protected or unprotected)
    .PRO format disk images. These disk images can then be accessed by the
    Atari using Steven Tucker's Atari Peripheral Emulator (APE) cable/software. http://www.atarimax.com/

    atarixfer module of AtariSIO package, by Matthias Reichl, 2002-
    Used to read/write disk images from/to a Atari drive connected to your Linux box with an 1050-2-PC cable or an APE ProSystem cable. Requires a 2.2, 2.4, 2.6 or 3.x series Linux kernel (with enabled module support) and a serial port with a 16550 or 16C950 compatible chip. Supports the .ATR disk image format. http://www.horus.com/~hias/atari/

    Fall?: Atari and Dorsett Educational Systems reached a licensing agreement
    that would bring Dorsett's Talk & Teach Computer-Assisted Instruction (CAI) System to Atari personal computer systems.

    November 29: Upon considering updated pricing estimates for the Atari Colleen system, Atari engineers considered targeting products at three consumer price points: Colleen would be the complete computer system, "Candy" would use the Colleen chipset but would be a non-expandable game player (no keyboard, no interface, potentially Atari VCS compatible), and "Elizabeth" would be the
    same as Colleen but with a 13-inch color monitor. (Decuir 1977 engineering notes p106-110)

    December: "Several other new personal computers, in the PET/TRS-80 price
    range,
    are coming soon...Atari (another video game manufacturer), and a European and Japenese [sic] company are also expected to enter the competition."
    (Micro #2 Dec77 p18; reprinted from "Northwest Computer Club News" Oct77)

    December 21: Design reviews of the Colleen system and ANTIC/CTIA/POKEY chips were held, fixing most of the specifications of the three chips that Atari
    was gearing to develop. (Decuir 1978 engineering notes p5)

    1978
    January 6: Howard Bornstein would be the first person to work on the Colleen system monitor/resident firmware. (Decuir 1978 engineering notes p5)

    January: "Other manufacturers are also looking at TV games as the way to enter the home-computing market. Atari is said to be working on a programmable unit featuring color graphics; it will use either custom chips or a 6502 micro." (ROM v1n7 Jan78 p60)

    Winter: Atari acquired the right to port Microsoft BASIC M6502 8K Version to the upcoming Atari personal computers. See: http://www.computerhistory.org/collections/catalog/102722318

    August: Carol Shaw joined Atari (Consumer) as a game designer.

    August: Atari (Consumer) hired NEOTERIC consultant Harry B. Stewart to oversee and document "Colleen" project systems software development. Stewart was
    hired by director of software development George Simcock.

    September: At Atari (Consumer), "Colleen" project systems software development efforts were essentially re-started, reassigned to several of the division's top VCS game programmers (and replacing Howard Bornstein in the role).

    October 6: Atari contracted with Shepardson Microsystems, Inc. (SMI, headed by Bob Shepardson) to create both a version of BASIC and a File Management Subsystem (FMS) for the upcoming Atari personal computers. The contract
    called for delivery by April 6, 1979.

    November: The Atari "Colleen" computer was named the 800 and the "Candy" machine was named the 400, named after their target price points of $800 and $400. The 400, which did not yet have a final case design, would not have a keyboard, but would support an external keyboard connected through controller ports 3-4. (Atari Inc.: Business is Fun, p. 460)

    November/December: As reflected in the preliminary Atari 800 Operators Manual printed for the January 1979 CES, Atari expected to ship the 800 with:

    Texas Instruments' petition for a waiver of Class I rules on RF modulators, in what was seen as an attempt to delay market introduction of the TI home computer. (TVDigest 3/26/79)

    April 9: In joining others including Apple, Interact, Mattel, and Radio Shack, Atari formally opposed Texas Instruments' RF devices waiver request from the
    US FCC by submitting a 60-page report accompanied by technical data showing that TI standards could cause massive interference in urban areas, and
    claiming that "TI simply presented the Commission with its self-serving appraisal of what it considered 'reasonable standards' for home computer manufacturers, and asked for authority to produce & market a computer line satisfying its own standards." (TVDigest 4/9/79 p11)

    April: Atari chip engineering technician Steve Smith departed the company (to Custom MOS, Inc.).

    April 16-June 30: Direct-mail "refund" promotion to all known (US) Atari VCS owners. Each of "hundreds of thousands" of owners would receive a blank check good for $2 on purchase of any of 28 VCS game programs. In addition,

    October: "Atari's production lines were stalled for about a week in October
    due to yield problems at one of its chip suppliers, Synertek. The low yields at the semiconductor manufacturer resulted in significantly reduced delivery
    of the MPU to Atari, resulting in about a 3-week delay in getting the
    computers into the marketplace." Electronic News, December 10, 1979, p. 83.

    November 9: Dale Yocum, previously of Telesensory, had joined Atari (Consumer) to establish and manage a 400/800 programmers group as Applications Software Manager (personal computers). Yocum had been hired by software manager Dennis Koble, but (like Koble) would report to director of software development
    George Simcock.

    November: Conrad C. Jutson, previously Texas Instruments marketing manager for personal computers, was hired by Atari (Consumer) as a consultant. (Compute!s 1st Book p2)

    December: "Atari is funneling large quantities of its 400 and 800 personal computers and software to Sears, Roebuck, while retail computer stores have been faced with late hardware deliveries and received very little, if any, software. Sears is offering the Atari 400, priced at $549, through its
    catalog [1979 Wish Book pages 654-655], and is spot-marketing the machine in its retail stores throughout California and the Chicago area. In addition,
    the firm is selling the Atari 800, priced at $999.99, in its California
    stores, but not through the catalog, a Sears spokesman said." Electronic

    working with native Atari hardware. A compressed data format.

    .SCP -"Flux image file" format (platform agnostic) invented by Jim Drew for
    his SuperCard Pro universal floppy disk copier/imager/converter
    hardware/software for Windows PC. Comparable to .IPF or the Atari-
    specific .ATX format. http://www.cbmstuff.com/proddetail.php?prod=SCP

    .SD -Early filename extension used with single density disk images for use
    with the Xformer emulators. Replaced by the .XFD extension.

    .XFD -"Xformer Floppy Disk" image format invented by Emulators, Inc. (Darek
    Mihocka) for the Xformer emulators (ST, PC). Known earlier, before
    support for arbitrary disk sizes was added, as .SD or .DD depending on
    the density of the imaged disk. The format consists simply of a raw
    sector dump of a disk. http://www.emulators.com/

    Subject: 10.1) How can I read/write Atari diskettes with my other computer?

    This sections lists solutions for accessing an Atari format 5.25" floppy disk using a PC with industry standard 5.25" floppy disk drive.

    Atari-Link PC (AtariDsk) V1.2 (c) 95-12-09 ==========================================
    by HiassofT (Matthias Reichl)
    Ataridsk is a program for MSDOS-PCs that allows you to access Atari floppy
    disks in double density (180KiB). All you need is a PC (XT or 286 should be
    sufficient) and a 5.25" floppy drive. Features of this tool:
    * Menu driven user interface
    * Read, write and format Atari disks on the PC
    * Small size (only 35KiB)
    http://www.horus.com/~hias/atari/

    WriteAtr V0.92b
    ===============
    by HiassofT (Matthias Reichl)
    With WriteAtr you can write double density ATR-images to Atari floppy disks
    on your MSDOS-PC. You can also create ATR-images of double density floppy
    disks! All you need is a PC and a 5.25" and/or a 3.5" floppy drive.
    Version 0.92b added experimental support for the enhanced density (1040
    sectors/128 bytes per sector) format. Please note: this format doesn't work
    with a lot of floppy controllers - use it at your own risk!

    UTIL
    ====
    - By Charles Marslett
    - Reads/Writes SS/DD 180KiB Atari disks.
    - http://www.wordmark.org/

    ===============================================================
    Here's some advice on using the above utilities from Hans Breitenlohner:

    There are two technical obstacles to interchanging disks between
    DD Atari drives and PC drives.

    1. The Atari drive spins slightly slower (288 RPM instead of 300 RPM).
    If you format a disk on the Atari, then write sectors on the PC, it is
    possible that the header of the next physical sector will be overwritten,
    making that sector unreadable. (The next physical sector is usually
    the current logical sector+2). The solution to this is to format all
    disks on the PC.
    (Aside: Does anybody know how this problem is handled on the
    XF551? Is it also slowed down?)
    Konrad Kokoszkiewicz answers:
    "The XF551 disk drive is not slowed down - these drives are spinning
    300 rotations per minute. To prevent troubles with read/write disks
    formatted and written on normal Atari drives (288 rot/min), the main
    crystal frequency for the floppy disk controller is 8.333MHz
    (not 8MHz, as in 1050, for example)."

    2. If the PC drive is a 1200KiB drive there is the additional problem of the
    track width.
    The following is generally true in the PC world:
    - disks written on 360KiB drives can be read on either drive
    - blank disk formatted and written on 1200KiB drives can be read on
    either kind
    - disks written on a 360KiB drive, and overwritten on a 1200KiB drive,
    can be read reliably only on a 1200KiB drive.
    - disks previously formatted on a 360KiB drive, or formatted as 1200KiB,
    and then reformatted on a 1200KiB drive to 360KiB, can be read reliably
    only on a 1200KiB drive.
    (All this assumes you are using DD media, not HD.)

    Solution: Use a 360KiB drive if you can. If not, format disks on the
    Atari for Atari to PC transfers, format truly blank disks on the PC
    for PC to Atari transfers.

    Jon D. Melbo sums it up this way:
    So a basic rule of thumb when sharing 360KiB floppies among 360KiB &
    1200KiB drives is: Never do any writes with a 1200KiB drive to a disk that
    has been previously written to in a 360KiB drive....UNLESS... you only
    plan on ever using that disk in the 1200KiB drive from then on out. Of
    course a disk can be reformatted in a particular drive any time for use
    in that drive. As long as you follow that rule, you can utilize the
    backward compatible 360KiB modes that most 1200KiB drives offer. ===============================================================

    AnaDisk + DeAna
    ===============
    While the above mentioned utilities work with SS/DD 180KiB Atari-format disks or SS/DD 180KiB SpartaDOS disks, the following combination of utilities has been used successfully to read SS/SD 90KiB Atari-format disks. So if you only have standard Atari 810 and/or Atari 1050 drives, you could look into:

    AnaDisk, created by Chuck Guzis at Sydex, Inc. in 1987
    - "Scan, edit, repair and copy just about any kind of diskette"
    - Version 2.01, November, 1989
    - One source for AnaDisk 2.06 (1992):
    http://www.retroarchive.org/cpm/cdrom/UTILS/22DISK/ANAD206.ZIP
    - Some have reported more luck with this than 2.07
    - One source for AnaDisk 2.07 26-Aug-92:
    http://www.retrocomputing.org/cgi-bin/sitewise.pl?act=det&p=776&id=retroorg
    - Last free version, readily available, but sometimes described as buggy
    - Sold to New Technologies Inc. (NTI) by Sydex in March 2000.

    OmniFlop (as of 2007)
    ========
    - By Sherlock Consulting (Jason Watton)
    - A 'universal' floppy disk reader, writer, and tester for the IBM PC or
    compatible which can handle alien floppy disk formats not normally
    supported by DOS, Windows and Linux.
    - OmniFlop on its own transfers disks between systems. If you want to access
    files, for example, on these disks then you need more - you will need to
    use OmniFlop to image the disk, then other software to interpret the
    filing system. OmniFlop alone only handles whole disks.
    - Features include, as of 2nd Sep 2007 v2.01m Release:
    - Read, write, and format Atari 8-bit format (90KiB). (Charles Doty)
    - Available: http://www.shlock.co.uk/

    ===============================================================
    The following more recent solutions involve connecting a standard "internal"
    PC floppy disk drive to a modern personal computer via USB port.
