Jeff Koftinoff’s father, Peter Koftinoff, was an avid HAM radio operator and electronics hobbyist.  During a trip from British Columbia visiting family in California, they found the original Apple II at the Byte Shop in 1978.  Jeff was 9 years old and his life was forever changed.  Devouring Steve Wozniak’s “Big Red Book” and the assembly code listings and schematics within, he dove head first into this grand puzzle. Soon, other people in the small town of Grand Forks, BC wanted to know where they could also purchase an Apple II, so the Koftinoff family started to sell Apple computers in Grand Forks for the Byte Shop in Vancouver BC.  This turned into the Kootenay Boundary Computer Center, which was probably second personal computer store in British Columba.

Jeff joined the Call-A.P.P.L.E. computer club and when he was 10 years old contributed his first published articles to Call-A.P.P.L.E. magazine.  After many hours playing games written in Integer BASIC and AppleSoft BASIC, he was influenced directly by the game “Evolution” by Don Mattrick from Distinctive Software which changed the gaming landscape for the Apple II.  Jeff learned to write in 6502 assembly with the mini-assembler at F666G, expanded to the Hayden Assembler, and finally the Big Mac assembler with which he created the “Cater Killer” video game published by Call-A.P.P.L.E. in 1984.

A fond memory was actually meeting the magical Val Golding who introduced the Apple Lisa in Renton, Washington.  Jeff then became interested in MIDI and created live MIDI software for Atari ST and started his own company.  From MIDI patch editing software for Roland Japan, SMPTE synchronization for Otari RADAR digital audio recorder, the Internet Filter for Windows, Linux, Mac OS, Digital Signal Processing for Level Control Systems and Meyer Sound, Jeff’s company was always working with exciting contracts.  Eventually, Jeff focused on hard real-time systems and digital audio network transport so he became involved in the IEEE Audio Video Bridging / Time Sensitive Networking work groups collaborating with other experts and editing the IEEE standards.  In 2015, Jeff shut down his company and moved to California to work at Apple on the next set of amazing technologies.
