One of Apple's first computers is up for auction and it could sell for as much as $600,000. The Apple-1, which was auctioned Tuesday 9th Nov 2021, is one of the few remaining specimens of Apple's (AAPL) initial computer. 

A Datanetics Keyboard Rev D, a 1986 Panasonic video monitor, an Apple-1 connection cable, and a power supply are included in the lot, as well as an Apple-1 "NTI" motherboard and an Apple Cassette Adapter in a koa wood case. 

It also comes with an Apple-1 Basic Manual, the Apple-1 Operations Guide, an original MOS 6502 programming manual, and two Apple-1 software cassette tapes. The computer was designed by Steve Wozniak and assembled and tested by Steve Jobs. Only two people have owned the Apple-1 on the market. In 1977, an electronics professor purchased this model, which he then sold to a pupil. 

According to the auction house, only six samples of the koa wood Apple-1 case remain. Due to livestock grazing and logging, koa tree numbers have decreased, making the wood rarer and more expensive. Only 200 Apple-1s were built, with 175 of them being sold. 

At an auction in Germany in 2013, a rare working model of the Apple-1 sold for more than $671,000. The computer was sold with a letter from Steve Jobs, Apple's co-founder, addressed to the computer's original owner. 

Jobs and Wozniak are credited with inventing the Apple computer in Jobs' family garage, hand-crafting the gadget, and funding the company with the sale of Wozniak's expensive calculator and Jobs' VW camper van. 

Apple is now one of the most valuable firms in the world, with a market capitalization of $2.5 trillion.
