This particular episode has a special meaning for me, personally. You see, as I've mentioned on earlier episodes, the TRS-80 Model I from Tandy/Radio Shack was my first home computer (even though my first programmable device was a TI58C calculator). I recall the joy and wonder of playing with the machine (it wasn't called the Model I at that time; just the TRS-80; as it was the first of the line) in the local Radio Shack store in 1977 and 1978 and the incredible rush of owning one in 1979; after my wife purchased a Level I BASIC machine for me as a gift for college graduation. That machine only had 4K of RAM and 4K of ROM (Tiny BASIC), as it was the entry-level machine, but it was a thing of beauty. I felt like I could do anything with that machine, even though my justification to the wife was that we could track our checkbook and recipes on it. I think she knew better, but went along with it anyway. The computer came with everything you needed, including a tape drive and black-and-white monitor, which was good for a poor recent college graduate. I quickly, as finances allowed with my new engineering job, upgraded the computer to 16K of RAM and Level II BASIC (a powerful Microsoft 12K ROM BASIC) and enjoyed the machine immensely, even using it in my job supporting the build-out of a new nuclear power plant back in those days.


I eventually sold off the Model I, in favor of a computer that had color graphics and sound (the Atari 800), but have always continued to have a huge soft spot for that first computer.


When I started the Floppy Days Podcast, one of the people that has always been on my bucket list to interview has been Steve Leininger, who, along with Don French while at Radio Shack designed the TRS-80 Model I, among other things. A few years back, I had the opportunity to participate in an interview with Steve for the Trash Talk Podcast, when I was co-hosting that show, but an ill-timed trip to the hospital for my son meant that I was not able to participate. While my son's health is of paramount importance, of course, I always wanted to get another chance to talk with Steve. Not only was Steve the designer of one of my favorite home computers of all time, but he also was a fellow Purdue University Boilermaker, who graduated just a year before I started there. The thought that I could have met Steve on campus if I'd been there just a year earlier was very intriguing to me, and fueled my desire to talk with Steve even more.


In the last episode (#141 with Paul Terrell) I talked about VCF Southeast in Atlanta in July of 2024. After I had made plans to attend that show, I was flabbergasted to find out that Earl Baugh, one of the show organizers, had somehow managed to contact Steve and get him to come to the show! I have to thank Earl for the work he did to make that happen. Here was my opportunity to certainly meet Steve, and perhaps even talk with him! I prepped some questions, just in case I was able to get an interview.


While at the show, I met Steve and asked him if he would be willing to do a short interview for Floppy Days while at the show. Amazingly, he was very kind and agreed to do that. We found a quiet room and I was able to talk with Steve for almost an hour. This show contains that interview.


Another note on this: as you'll hear in the interview, the connection to Steve is even stronger than I realized! He not only went to my alma mater, but also grew up in some of the same towns that myself and my wife did. We personally peripherally know some of his relatives. Things like this really do make you think the world is small!


One other, final, note: This interview even ties into the recent and continuing interviews I've been publishing with Paul Terrell. As you'll hear in upcoming episodes with Paul, and in this interview with Steve, Steve actually worked at the Byte Shop before getting the first job with Tandy, and in fact his work at the Byte Shop directly led to him getting hired by Tandy to design the Model I.


Anyway, I hope you enjoy the interview as much as I enjoyed getting it. I am overjoyed I finally got the chance to talk to one of my vintage computer heroes, Steve Leininger!
