Description

This Apple-1 was built in a 19 inch rack. It is the only known Apple-1 in a rack. The keyboard is built-in a beautiful wooden case. The Owner used the prototype area for what it was designed: to modify the Apple-1 a little bit.
Handwritten number 01-0073 and round stamp with number 7 in the middle on the back.
The added components (inverter ICs) were necessary to use some keyboards in 1976. Many Apple-1 were modified for auctions in the past. Those added parts were removed and a 1977 or even later Apple II keyboard was attached. The Dryden Apple-1 is still in the 1976 state including the keyboard. Not everyone agree that it is worth to destroy the history of the Apple-1 mainboard and remove 1976 parts necessary to use some 1976 keyboard just to make the mainboard looking “clean” and add much later produced keyboards.

History

Bought by John Dryden (California) on Nov 30 1976 in a small computer shop in Berkeley called Kentucky Fried Computers. Later this company became North Star Computers.
Apple offered Apple-1 owner in 1977 to trade-in the Apple-1 for an Apple II. In 1979 John Dryden tried to do so but Apple answered that they have no information about a trade-in.

The Apple-1 was kept by first owner until 2017 when it was auctioned by Breker Cologne in Germany. Expert Rudolf Brandstötter checked the Apple-1 and added another keyboard and a new power supply for 'daily use'. Original keyboard is still untouched in the wooden case. Original power supply exist but it is to risky to use it. New owner is Achim Baqué from Germany.
Surprisingly low auction result has nothing to do with the Apple-1 and the owner know the reason but can't talk about it. After auction US$ 350,000 were offered twice but not accepted by current owner.

This Apple-1 was on display for 7 month at an art exhibition in Karlsruhe, Germany. From July 14, 2018 till February 10, 2019 at ZKM, Center for art and media, Lorenzstraße 19, 76135 Karlsruhe. www.zkm.de – use online translator. The Apple-1 was provided free of charge for the exhibition.
Exhibition was called „Kunst in Bewegung. 100 Meisterwerke mit und durch Medien.“ (Art in motion. 100 masterpieces with and through media).

The Apple-1 is still in the state of 1976. The first owner added some parts and replaced 2 sockets. Current owner believe, that after 40+ years it is part of the history and belongs to the mainboard. He preserve this state. Even no cleaning was done. And that’s the way every museum like/want it!

Auctioned

May 2016

Components

White ceramic MOS MCS 6502 CPU (1576), purple ceramic Motorola MC6820L PIA (7636), 8 KB plastic DRAM, original components. Blue capacitors.

Equipment

Original Apple Cassette Interface. Unique 19 inch rack. Keyboard in unique wooden case. Cassettes, original Operation Manual, original ACI manual, cassette recorder and a typewritten preliminary manual. Sanyo monitor. Unique letter from Apple Company dated April 2 1979 and signed by Carol Sandler. Original bill from Nov 30 1976. Many handwritten documents. Some notes of phone calls between owner and Steve Wozniak. And more.

State

Very good. Prototype area populated with additional electronics. Additional wires on the back. All hardware was added at prototype area by first-hand owner John Dryden in 1976/1977 because he used a keyboard with inverted signals. The extra chips are inverters. Works with 'regular' serial keyboard as well. Same owner replaced two IC sockets.
The current owner decided to preserve the history and changes made by first owner soon after buying the Apple-1. All added parts are in place, no chips are changed etc.

Remarks

In 2018 current owner Achim Baqué asked John Dryden about the Apple-1. Thankfully John answered the questions in great detail. It completes the history and provenance of this Apple-1.

For what did you use the Apple-1? For fun, education or any other purpose?
I was a software engineer and as a hobby I liked to play with electronics. I bought the Apple-1 to experiment with because I finally had the chance to own my own computer. I wrote a text editor program for it in 6502 assembly language, which I had to assemble by hand, and then key into the Apple-1 monitor program a byte at a time. I sent an article about the editor to (the newly established) Byte Magazine but they never printed it. I had a few phone conversations with folks at Apple about the editor but they had their own editor in the works and they liked theirs better because it had more "bells and whistles," as I wrote in my handwritten notes, which you [Achim] have. I also built a hardware interface and wrote a driver for an IBM Selectric typewriter, which I used as a printer. Along with friends, we had plans to build a software-driven patch-cord switching network for the audio synthesizer that one of us owned. We all went our separate ways before the project was complete.

What is the purpose of the added chips on the mainboard?
The keyboard I used produced inverted signals as compared to the signals expected by the motherboard. The extra chips are inverters.

Why did you buy the Apple-1 in Nov 1976 and not any other computer?
I looked at other personal computers that were coming out at about the same time, but I liked the Apple better because it uses a 6502 microprocessor, which I felt was superior to the 8080 used on most other machines.

You bought it in the Byte Shop in the Bay Area?
No, I bought it at a small place in Berkeley called Kentucky Fried Computers. You [Achim] have the receipt. It was a lot of money for a poor hippie in Berkeley, but I really liked the idea of a computer that I could own and program for myself.
