DeviceLogics acquired DR DOS from the Canopy Group, a Utah technology venture group, and has plans to release in Spring 2003 of an 8.0 version of DOS, bringing it up-to-date with core embedded functionality to include a TCP/IP stack, FAT 32 device drivers and other upgrades. DR-DOS originated in 1987 at Digital Research, Inc.; was then acquired by Novell in the early 90s; in 1996, DR-DOS was acquired by Caldera, Inc., the same company that sued and settled out-of-court with Microsoft Corporation over DOS-related anti-trust allegations; in 1998, it was spun out to Lineo, Inc. (a Canopy company) where it underwent enhancements targeted at the embedded market and, in October 2002, was acquired by DeviceLogics, Inc. DeviceLogics, Inc. was founded by Bryan Sparks, Bryce Burns and Troy Tribe for the advancement of DOS as an embedded solution. Visit for DR-DOS 7.03, a DOS-based web browser, and additional information and updates. Please send email to for further information.  For the links below for DRDOS.COM and DRDOS.ORG please use MS Internet Explorer or the latest Netscape 7.x.



OpenGEM 2.0.0 is the latest OpenGEM release. You can get it for free by going to the OpenGEM downloads page. OpenGEM 2.0.0 works with all version of DOS after 3.3 (MS DOS, DR DOS, REAL/32, etc.). OpenGEM 2.1.0 will be out on the 6th of June 2003, and will be another little leap towards a complete GUI distribution for DOS. The fonts and printer drivers will be expanding, the GEM documentation will start to increase its presence, and there will be many little tweaks to tidy up the way OpenGEM works.  The OpenGEM FAQ is up and has full information and installation details for OpenGEM.
Special thanks go to Shane M. Coughlan in the UK for spearheading OpenGEM development. Shane is focused on getting OpenGEM running on as many systems as possible, and promoting it. It is a pretty neat, free GUI, and has a lot of potential uses - including for new types of embedded devices. Development is progressing well and ports are in progress for other languages including German, Russian, Spanish, and Chinese.
If you are able to lend a hand (be it with programming, documentation or spreading the word), please let Shane know by contacting him at  You may also participate in the GEM Forum via email at Gem-Dev@Simpits.Org and GEM Annoucements at A series of net utilities is also contemplated for GEM which would include: NSLookup, Ping, Traceroute, Telnet, FTP, HTTP support and more.

Dr. Gary A. Kildall

In Memory of Dr. Gary A. Kildall

All of the products above would not have been possible without the valiant and brilliant work of the founder of Digital Research, the late Dr. Gary A. Kildall.  On July 11, 1994, Gary Kildall passed away following a blow to his head at the Franklin Street Bar & Grill in Monterey, California on July 8, 1994. At the time of his death, Gary was 52. He was born in 1942, a few years before the first electronic computer even existed, and his software made possible PC computing as we know it at the turn of the 20th century. He is survived by a son. Scott, and a daughter, Kristin, as well as his former wife, Dorothy Kildall, with whom Gary co-founded Digital Research, Inc. in 1974.

Gary created the first Operating System for the microprocessor, CP/M.  The most advanced current version of CP/M in 1999 is IMS Ltd. REAL/32.  CP/M also serves as the basis of all modern DOS versions including the outstanding Caldera DR DOS and other derivitaves including PC-DOS from IBM, and MS-DOS from Microsoft, whose position in the computer industry is based on its unauthorized 1981 "cloning"of Dr. Gary Kildall's Digital Research CP/M, which gave birth to the IBM PC standard upon which Microsoft MS-DOS, Windows CE, Windows 95, Windows 98, and Windows 00 (now 2000, formerly NT) are based today.

On July 23, 1996, Caldera Inc. acquired the entire assets of Digital Research Inc. from Novell Inc. and on July 24, 1996 filed an Antitrust Lawsuit against Microsoft Corporation.  The Final Version of this suit was ultimately settled in Caldera's favor in January 2000 prior to going to trial in Utah. Hopefully, some justice will finally be achieved.  Gary never wanted to file suit against Microsoft because he always believed that in the end excellence in programming would win in the marketplace.  We continue Gary's belief, and now must come a public awareness of the truth and a desire for justice must awaken to make the vision of an open and exciting software industry where many companies can flourish equally a reality.

All of us who knew and loved Gary are dedicated to continuing his work, his dreams, and his collegial sharing and caring about people, while working to open new frontiers in software research and development for the benefit of all.  Gary forever changed computing by laying the foundation for popular PC operating systems, but most importantly, Gary was the greatest teacher any of us who knew him and his work could ever have had.
