The meetings consist of computer classes on the older computers that are no longer sold. They are open to the public at no charge. DMA members are encouraged to come and get answers to their computer questions that are not available from the local computer stores. The classes cover software and hardware and how to upgrade or repair common troubles. Software covers spreadsheets, word processing, music, graphics, DOS, Win3.1, Win95, Win98, WinNT, and Win2K. Hardware covers memory, disk, CD, floppy disks, zip drives, power supply replacement, cleaning, etc. All classes are tailored to the needs of the members and can be most subjects at any time. If you call Gary at 237-5021 during the week, he can prepare to answer your questions or many times a quick answer on the phone is all that you may need. Past classes showed how to connect the computer to MIDI keyboards and writing music on the computer. Making a spreadsheet to balance your checkbook. Making a form to fill out for daily records. Replacing a bad CD recorder and cleaning. Downloading your photos. Replacing a bad power supply. Running anti-virus software and updates. Rebuilding hard disk systems after a crash. The classes can also show the pre-PC computers that are in the Dayton Computer Museum. The students from Wright State will be getting information for their class work as assigned by their professors. Local computer stores have sent customers to the meetings to get help on the older machines. You have questions? We really have the answers!

Call Gary Ganger at (937) 237-5021 for more info.

Digital Photography SIG (Revised May 29, 2010)

Calling all digital photographers

Ideally, the SIG would have two meetings a month; one to learn about digital darkroom techniques, the other to go out into the field and learn how to use our cameras. This will be a free-form SIG meeting to discuss all aspects of digital photography in a friendly small group atmosphere. We will be open to all digital systems including still, digital movie, scanning of regular photos, and capturing movies from analog (VHS and 8mm) formats. The group will use tools such as Photoshop, Photo Editor, VideoWave, Moviemaker, & others to optimize our work.

If you are interested in participating or in becoming a group leader for the field portion, please contact Nancy Christolear or Dave Lundy (937) 426-1132, or e-mail digiphot-contact@dma.org. Our first meeting was held in the CompUSA Training Center at SR 741 and SR 725 from 7:00 – 9:00 PM Thursday, January 2, 2003. We immediately discovered that we needed a larger meeting room, so moved to Wright State University. Eventually, due to increased enrollments, W.S.U. didn’t have classrooms for us, so we moved to 119 Valley St. After DMA vacated Valley St., we held meetings in various public libraries and any where else we could find. Since meeting locations were becoming more difficult to find, and attendance had been lagging, we decided to suspend monthly meetings until further notice. May 27, 2010 was our last regularly scheduled meeting. Please see our events page for current details.

Please contact Nancy Christolear or Dave Lundy (937) 426-1132, write to digiphot-contact@dma.org, or check our web site for more details.

Hands-On SIG (New Dec. 1, 2004 – updated Aug. 25, 2009)

The Hands-On SIG has a new leader, beginning with the May 24, 2006 meeting. Welcome Elliott Lake! Elliott has some ideas and would like additional input from the SIG. They are:

  • Divide the meeting up into segments (like the Linux SIG).
    • General Q&A session followed by the meeting topic would be an example of this approach.
  • Short presentation about a piece of software being used by a group member. This would be about a 15 minute presentation.
  • Hands-on problem solving of equipment problems / software problems. This will require the member with the problem bringing in the system, if possible.
  • Returning to the certification training, starting with A+.
  • In-depth presentation about software being used by a group member. This would be a 30 – 60 minute presentation.
  • Study the use of Linux and MS in the workplace.

Thanks, George, for your five years of service as the group leader. You did a great job and deserve the chance to sit back and relax.

The Hands-On SIG is now closed. It was to have been replaced Jan. 27, 2010 with the “IT” SIG, but that is now in limbo due to Elliott Lake’s death Wed. Nov. 11, 2009. We’ll miss you Elliott! Rest in peace.

“IT” SIG (New Aug. 25, 2009 – updated Nov. 15, 2009)

Elliott Lake, the SIG leader, passed away Wednesday, November 11, 2009, so the “IT” SIG is in limbo until a new SIG leader is found.
