The Data General/One Model 2 — The Improved DG-1
The Data General/One Model 2 was an improved version of the original DG-1, released by Data General as part of their ongoing refinement of the laptop platform over its four-year production life. Data General upgraded the DG/One numerous times in response to customer feedback, addressing the original model’s most significant shortcomings while maintaining the fundamental clamshell design that had established the laptop form factor.
Addressing the Original’s Weaknesses
The Model 2 incorporated improvements to the areas that had attracted most criticism of the original DG-1. The display — widely regarded as the original’s greatest weakness due to its poor contrast and lack of backlighting — received attention, and RAM configurations were expanded to better meet user needs. The 3.5-inch floppy situation had also improved by the time Model 2 variants reached users, as the format was gaining wider adoption and more software was becoming available in the smaller format.
Data General’s Minicomputer Heritage
Data General was founded in 1968 and became one of the most important minicomputer manufacturers of the 1970s — a company made famous by Tracy Kidder’s Pulitzer Prize-winning book ”The Soul of a New Machine,” which documented the development of the Eclipse MV/8000 minicomputer. The DG-1 represented a remarkable pivot from $258,000 minicomputers to a $2,895 laptop — reflecting the profound transformation that microprocessors brought to the computing industry.
