Hey there! As a fellow computer history enthusiast, I wanted to share with you the fascinating story of the Osborne 1. This revolutionary machine from 1981 was the first commercially successful portable computer. Though it looks laughably bulky today, the Osborne 1 paved the way for all the sleek laptops and gadgets we now take for granted. Let‘s dive in and explore why this iconic computer was so groundbreaking.
Adam Osborne’s Portable Computing Vision
The Osborne 1 was the brainchild of Adam Osborne, a writer and computer fanatic who saw the potential for portable machines as early as the 1970s. Osborne was inspired by an unwieldy briefcase computer called the CompuCase but realized it could be designed much smaller and lighter.
In 1980, Osborne teamed up with engineer Lee Felsenstein, who had worked on the early portable CP/M computer Sol-20. Together, they set out to design a truly portable computer you could easily transport and use anywhere. As Osborne said:
"My objective in working on a portable personal computer was to provide enough power in a package small enough to be transported lightly, but containing input and output features comparable to those of a desktop machine."
The product of Osborne’s vision was unveiled in 1981 – the world‘s first mass-produced computer small enough to fit under an airline seat!
Groundbreaking Specs and Capabilities
So what exactly could the 24-pound Osborne 1 do? Here are its groundbreaking features for the time:
- 4 MHz Z80 CPU – Fast enough for basic tasks
- 64KB RAM – Decent memory for applications
- 90KB floppy drives – Stored up to 200 pages of text
- 5” screen – Tiny by today’s standards but portable
- CP/M 2.2 OS – Standard for early ‘80s microcomputers
- Bundled software – WordStar, SuperCalc, Microsoft BASIC
While laughable today, carrying this amount of power anywhere was revolutionary. Early adopters were amazed to have a capable computer they could take on trips or move room to room. The Osborne 1 also introduced the “software package” model including useful programs right out of the box.
However, the tiny screen and weak Z80 processor still limited the experience compared to systems like the Apple II and newer IBM PC. But for 1981, it was a miracle of portability!
Overnight Success and Eventual Downfall
When released in 1981 for $1795, nobody expected the Osborne 1 to sell well. But shockingly, Osborne Corp was shipping 10,000 units a month by late 1981! It was a smash success, becoming the first computer to make a dent in the mainstream market.
But competing systems quickly surpassed the Osborne 1:
- Kaypro II – Better screen and storage, less expensive
- IBM PC – More powerful 16-bit CPU, abundant business software
- Apple II – Large software library and user-friendly design
Osborne made a fatal mistake announcing successors too early before they were ready, killing Osborne 1 sales. This led to massive losses and bankruptcy in 1983. But still, the company proved the demand for portable computers.
Lasting Influence on Portable Computing
Despite its early demise, the pioneering Osborne 1 made portable computing mainstream. Here are some examples of its lasting impact:
- Validated consumer demand for portable PCs 5+ years before laptop popularity
- Inspired design of later ‘luggables‘ like the Kaypro II
- Direct ancestor of laptops of the late ‘80s/early ‘90s
- Changed workflow by letting business users transport PCs
“Adam Osborne’s work made computing more accessible for those on the move,” said technologist Steve Wozniak. The Osborne 1 directly enabled the development of portable computing in the decades to follow.
So while primitive today, we owe a debt to Adam Osborne and the Osborne 1 for making computing easier to take anywhere! Its innovative design and success changed the future of portable PCs.
