The Rugged Computer That Conquered The Eighties

Before sleek laptops existed, the Kaypro dominated by being essentially a portable tank. These heavy machines were built so tough that they were marketed as rugged, go-anywhere workstations for professionals.

Founded by a company that originally made industrial measuring tools, Kaypro brought that same durability to personal computing. Instead of fragile plastic, their machines used sturdy metal cases that could survive being lugged around in the trunk of a car. By bundling massive amounts of free software with every purchase, they quickly outpaced their fragile rivals. It remains a classic example of how over-engineering a product for reliability can capture an entire market.
