The Apple-1, one of the first computers of Apple, was put on auction on Tuesday and its price can hit up to $600, 000.

John Moran auctioneers said that the computer is among Apple’s surviving examples of the first computers worldwide.

The listing said that the auctioned items include the Apple Cassette Adapter in a koa wood case, an Apple-1 “NTI” motherboard, a Datanetics Keyboard Rev D, as well as a 1986 Panasonic video monitor, the computer’s connecting cord, as well as a power source.

Added to these, the auctioned unit also includes a Basic Manual, Operations Guide, as well as an original MOS 6502 programming manual, and a couple of software cassette tapes.

Steve Wozniak has designed the Apple-1 while Steve Jobs has assembled it.

Two persons have owned the computer on sale. The auctioneer said an electronics professor bought the unit but sold it in 1977 to a student.

Only 200 Apple-1 computers were made.

“This Apple-1 has recently undergone an extensive authentication, restoration, and evaluation process by one of the foremost experts in the field, who inspected all components and generated a full condition report for the Apple-1,” the listing reads.

According to the auction house, only six koa wood Apple-1 case examples remain. The particular tree sells at a higher price and becomes rare as the koa tree population becomes smaller because of logging and cattle grazing.

In total, 200 Apple-1s have been made and 175 of them have already been sold.

The listing said fifty of the Apple-1s were purchased by a certain ByteShop store owner in Mountain View, California named Paul Terrell.

The auctioneers said Terrell was allegedly dismayed when he received the units as he was expecting ones that are plug-in-ready.

He was reportedly been calmed by Jobs who said each of the boxes include complete elements to form an operating computer and that his shop could gain cash when they upsell the units.
