      • Getting started with OPUS/ONE OPUS/TWO
        07/29/09
        My first digital group system was Audio cassette based followed shortly by a phi-deck addition although I bought an 8" diskette drive I never purchased a controller or operating system. OPUS was introduced in flyer #11 and I was tempted, but at $110 for OPUS/TWO it would have to wait until I a

      • Thank you Bryan - The end of an era
        07/11/09
        I've been contemplating this article for a while now, ever since I discovered that a friend was being forced to abandon this enjoyable hobby. Maybe I just haven't wanted to sit down and write it which forces me to admit that we're at the end of an era. Maybe I'm just saddened t

      • More - Newer Bridge Issues
        02/22/08
        With the new additions to my hardware collection came a few unexpected surprises, newer "Bridge" newsletters than I thought existed! I thought Volume 5 number 1 was the last one, but I now have 5-2, 5-7 and 5-8. Unfortunately 5-3 through 5-6 are not part of the stash, so if anyone out th

        I began corresponding with Richard Brandle in August of 2007. He was kind enough to provide me with images of several "Bridge" newsletters to complete the known list of volumes/issues. Thanks again Richard.

        Richard built a complete system in 1975 and lots of extras, here is a

        02/17/08
        I haven't been active for about eight months due to work and other commitments, but it's time to get back to work.

        The first project was to get rid of all of the stupid posts on this site advertising various unsavory stuff. The good and bad of the internet I guess. So unfort

        Sitting busily cataloging diskettes from a recent find of DG related stuff, I was working at the Bytesmaster that I luckily acquired directly from Dr. Suding about three years ago when I heard the unmistakable sound of electronics frying..... I immediately (within a couple of seconds) shutdown the s

      • The UnROM
        05/08/07
        One of the complications of working with Digital Group systems was the different ROMS that could be used to startup the system (Audio, Phimon, Diskmon, OASIS, MCSO). Later in the chronology, if you had a Disk system, you could run a program called DDBOOT after booting into Diskmon to allow you to b

      • PHIMON-H Version 3.0 Documentation
        04/23/07
        In bringing up a brand new out of the NEVER OPENED BOX phi-deck drive I was looking through some old tapes and ran across a copy of PHIDOC.TX which contains the updated documentation for PHIMON. This version "communicates" in hexidecimal instead of octal as well as supporting updated comm

      • History from Microworks Point of View
        04/09/07
        Just added a very intersting article from "Brown Box Journal", March 1982 describing digital group history from Microworks point of view. The article can be found here or you can find it in the History section of the articles page.

      • Restoration begins - Keyboard
        04/08/07

        Early 2005: I was fortunate enough to find a system that was still running albeit in a strange configuration. When I received the system, it was in pretty "odd" shape. While it seemed to work well, the guts were very unusual for a dg system. The normally fragile memory boards had bee

        04/05/07
        Actual notes in the HELP WANTED section of the first issue of BRIDGE. The last entry asking for help when the oven is turned on was an actual problem suffered by more than one DG enthusiast..... These really were the pioneering days!

        03/29/07
        In this continuing article, I will attempt to cover all aspects of restoring a digital group system beginning with the keyboard and main unit followed later by phi-deck, diskette drive and printer restoration. Bryan Blackburn has an excellent site with lots of photos of his restoration projects.
      • Launching new digital group web-site
        03/29/07
        Well here we go (finally)! I've been threatening to build a web-site and blog related to "the digital group" computers for some time (at least three years) and now I've done it.....

        The purpose is threefold.

        1) To provide a place for others to learn about t
