Steve Leininger

Keynote Speaker

Steve Leininger was the engineer that created the TRS-80 in 1977, one of the first personal computers available. Steve is retired, but he has not run out of things to do. Growing up with undiagnosed ADD. and dyslexia, Steve would often be easily distracted (SQUIRREL!!) but did well in school because he had so many interests and a mom that fed those interests. His current list of "things to do" include developing STEM presentations for elementary school students, being a mentor, maker, and board member for a makerspace in Colorado Springs, hiking the many trails in the Pikes Peak region, splitting wood for a firewood ministry in the mountain community up the pass from Colorado Springs, and orchestrating monthly training and resource meetings for leaders in the local Boys Scouts of America council. A partial list of other interests include embedded computers, crafts, mechanisms, toys, woodworking, carving, cooking, musical instruments, science, and magic.

Jim Brain

"The CoCo As Peripheral: Controlling the Color Computer from the Cartridge Port"




Bio: In high school, when Jim's family went to the mall, they dropped him off at the local Radio Shack, where he spent hours selecting and re-selecting bubble packs of resistors, capacitors, transistors, and integrated circuits in order to build ever increasingly complex digital and analog circuits based off his Forrest Mims engineer mini-notebooks (which he purchased at Radio Shack as well). Growing up in the home computer era, Jim picked a career path early, pursuing a B.S in Computer Engineering at the University of Illinois and enjoying a 30+ year career in Information Technology and Security. He's spent the last 21 years ensuring classic systems not only continue to function but can take advantage of new technologies, while ensuring these solutions remain available through open source licensing.
