Competition

 

In the Media

"Both Diamond Computer Systems boards - the $249 86C801-based Diamond Stealth 24 and the $349 86C928-based Diamond Stealth Pro - produced an excellent Graphics Winmark score. The boards' AutoCAD scores were less impressive, though, and they had minor problems either with artifacts or properly clearing the screen in that environment. Additionally, the Stealth Pro needed a boost to get up to the level of DOS performance most of its 86C928-based peers provided."     PC Magazine, April 1993
