I also got a TI-99/4A as my first machine. Fun story about "on the path:" Texas Instruments actually made a bunch of those machines in Johnson City, TN. I moved there in the late 90s and got a job working for Siemens, who had bought the industrial automation division of TI a few years prior, which included the Johnson City plant. I had a desk in a lab in a large electronics manufacturing space that was repurposed as a cube farm and was privileged enough to work with some amazing people, a few legit graybeards and a bunch of old school EE types. In passing, one of them gave me a history lesson about the plant and what they had done there in the past.
It turned out that my desk at my first "real" IT job was fifteen feet from where my first computer was made.
Coincidentally, and not as happy a memory, my mother came down to visit me at Christmas that year, and I showed her my office between Christmas and New Years when almost no one was in the office. She took a picture of me at my desk, and that picture hung in her home ever since. She just passed away last December, twenty five years to the day after that picture was taken.
