It's fascinating to learn about this historical document related to the Apple-1 computer and Steve Jobs' handwritten notes. The Apple-1 computer holds a significant place in the history of personal computing as it was one of the first personal computers designed and hand-built by Steve Wozniak in 1976. Here's a breakdown of the information provided:
Document Description: The document in question is a draft of an advertisement for the Apple-1 computer. It's written on an 8.5 x 11 binder sheet in black ink, dating back to 1976. This document has historical importance as it sheds light on the technical details and features of the early Apple computer.
Provenance: The document was acquired by the consignor (the person selling it at auction) during a visit to Steve Jobs' garage in 1976. This garage is renowned as the place where the early Apple computers were assembled and where the company was founded. Thus, the document has a direct connection to the early days of Apple Inc.
Technical Details: Steve Jobs' handwritten notes on the document provide insights into the technical specifications of the Apple-1 computer, which were ahead of its time:
- Power Supplies: The document likely described the power supply components of the Apple-1, which were essential for its operation.
- 8K Bytes of RAM: RAM (Random Access Memory) is a critical component for a computer's functionality. The Apple-1 had 8,000 bytes of RAM.
- CRT Terminal with Keyboard Input: This suggests that the Apple-1 had a built-in Cathode-Ray Tube (CRT) terminal, which was a display technology common in early computers. It also supported keyboard input.
- Composite Video Output: This indicates that the computer could generate a composite video signal for display on a monitor or TV.
- Expandability: The document mentions expandability up to 65K via an edge connector. This means that users could potentially upgrade and expand the computer's memory and capabilities.
- Microprocessor Preference: Steve Jobs expressed a preference for the 6501 or 6502 microprocessor. These microprocessors were commonly used in early personal computers. Jobs likely favored them because they supported the BASIC programming language, which was important for early computing enthusiasts.
- Integrated Circuits (ICs) Count: Jobs provided the exact count of integrated circuits (ICs) used in the Apple-1. This information emphasized the computer's potential for growth and expandability.
Steve Jobs added a personal touch by including his signature, contact details, and the address of his parents' home, which served as the first headquarters for the Apple Computer Company at "11161 Crist Dr. Los Altos, CA 940." This inclusion highlights the company's modest origins.
Steve Jobs concluded the advertisement by emphasizing that the Apple-1 was an exceptional opportunity, offering the board and manual together for the price of $75, making it a unique deal.
