As Woz was the only person who could answer most customer support questions about the computer, the company offered Apple I owners discounts and trade-ins for Apple IIs to persuade them to return their computers. These recovered boards were then destroyed by Apple, contributing to their rarity today.
Production was discontinued in 1977 with the introduction of its successor, the Apple II.
The board shown here is the Mimeo which is an exact replica of the Apple I. This board was completed in early 2019 after a couple of weeks of construction. Most of the parts were in my extra parts collection and all of the parts are date correct. The 6502 CPU is a very rare White Ceramic MOS 6502 with date code 50th week of 1976 and the 6820 was 26st week of 1975.
