Priming the Pump:
How TRS-80 Enthusiasts Helped Spark the PC Revolution


    About the Authors


Since closing out their TRS-80 software business in the mid-1980s, David and Theresa Welsh have been busy raising their daughter and active in IT work, community involvement, and writing/editing/photography endeavors.

Before he immersed himself in Z80 programming, David had been a professional photographer. He returned to doing occasional photo assignments, and, more recently, has been working on digitizing and cataloging his considerable accumulation of images, mostly in black and white film. David played an active role in his daughter's education, establishing a computer lab at her elementary school, using old, donated computers. Theresa served as a "Picture Lady," introducing kids to computer art.

After the demise of the TRS-80 business, Theresa worked at EDS as a technical writer, then moved to Ford Motor Company in various contract positions through the 1990s, serving as newsletter and web editor at the Research Lab until the auto industry cutbacks in 2005. David also did contract assignments as a technical writer and consultant during this period through Explainamation ( www.explainamation.com). He has served as chairman of a local organization working for community development in the interests of residents along the border between Detroit and its northern suburbs.

Theresa co-authored an award-winning business book (The Brave New Service Strategy, with Dr. Barbara A. Gutek) and wrote a novel for young adults, Tara, Initiate of Heliopolis. She also does editing for other authors and has an ongoing relationship with the Alan Kardec Educational Society (AKES), editing older works translated from Portuguese and French. She is an avid book reviewer for her website, www.theseekerbooks.com, and at amazon.com (see her profile page), where she has over 80 reviews.

Daughter Amy spent her senior year in high school as an exchange student in the Czech Republic and traveled thoughout Europe. Today she lives in New York City and aspires to a career in media.

W're just back from the Vintage Computer Festival (VCF), held November 3 and 4 in Mountain View California. We were the first presenters, and had an enthusiastic audience. We brought a slide show we put together from material in our book, which used a lot of the old ads and photographs. Several media organizations interviewed us, and we're pleased that people still want to know what happened back in the late 1970s that led to the explosion of personal computer use.

VCF featured planty of heavy hitters and I (Theresa) especially enjoyed a session on phone phreaks and found one of the attendees was none other than Cap'n Crunch himself! The exhibits were fascinating too; one was a complete working Difference Engine made out of erector set parts! There should be pictures and video of the sessions online soon at the VCF website: www.vcf.org.

The 30th anniversary year for TRS-80 is gone (1977 - 2007), but it's been a great year for our book. We've had nothing but favorable comments from our readers. I got a wonderful email from a former Radio Shack employee who wrote:
   "Thank you for writing the book! I was delighted to find it on Amazon and read it over Christmas. It was nice to read so much background on the events I experienced working for Tandy from 1980 to 1993... Reading your book brought back so much. Time spent at the store as a salesperson, learning most of what I knew about the TRS-80 from our teenage customers! The blitzes. Disk doubling punches. An absolute prohibition on outside software and magazines in the store. Every model you mentioned and some you were too kind to mention such as DT-1 and DT-100 terminals, a slew of roman-numeraled printers, the phrase "near letter quality", and millions of dollars in ill-conceived marketing. I wish I still had a "Diskette of the Month" club card, I'm sure that closed a lot of business customers!"

The year saw two other important books published about those years: iWoz by Steve Wozniak, and On the Edge: The Spectacular Rise and Fall of Commodore by Brian Bagnall. I have read (and reviewed for amazon.com) both books and can recommend them as adding to our store of knowledge.
