Dave Haynie is the former Commodore International chief engineer on high end and advanced projects. He is still quite vocal in the Amiga community.

Dave was born David Bruce Haynie on May 23, 1961, in Summit, New Jersey, United States. He moved to Colts Neck, New Jersey, in 1966, where he lived out his childhood with his three younger sisters. A few early Heathkit projects, and, at the age of 12, a run-in with his dad's borrowed HP desktop calculator changed his life forever. From 12 years on, he taught himself programming, initially on timeshare systems from his dad's account at Bell Laboratories. Later on, he wrote programs on his best friend Scott Scherer's Commodore PET 2001, the first home computer he had seen up close.^{[citation needed]}

He left for college at Carnegie Mellon University in 1979. Four years later, he graduated with a double BS in Electrical Engineering and Mathematics.^{[citation needed]}

He started work at Commodore in 1983 as an engineer under Bil Herd. His first project was to help complete the TED systems comprising Plus/4, C16 and more. After completing the Commodore 128 Bil Herd left the company and Dave Haynie was promoted to chief engineer in the low-end group. After Commodore acquired Amiga, Dave Haynie ended up primary engineer on the expandable A2000 computer. Later, he joined Bob Welland on the A2620 CPU module, and launched the follow-up A2630 the year thereafter. These were delivered in the A2500/20 (1989) and A2500/30 (1989).^{[citation needed]}
