We are always looking for original Apple-1, manuals, price lists, ads etc. The curator himself preserve and collect anything related to the Apple-1. And we know many Apple-1 owner and enthusiasts looking for Apple-1 (parts).

The mission to preserve original Apple-1 computer:
Many replicas are built, and many date-code correct parts are used for it. With some people making replicas in mass-production it is getting more and more difficult to find spare parts. Some buy whatever is possible and some gamblers demand huge sums for individual chips.
For many everything about the Apple-1 is just the value. From a historical point it is very important to preserve them and the work of Steve Wozniak. It's not about whether you like Apple or not. For example, nobody likes to see spare parts from modern cars in a classic cars and that’s how it is with the Apple-1.

Apple-1 owner need help to get hands on date and period correct parts. Every single IC counts.
