Dense-Pac Microsystems Inc.: The company said Tuesday it has received a $1-million purchase agreement from Radstone Technology, a European electronics company.

Most of Radstone’s order is for Dense-Pac’s first generation of “stacking” products, which allow computers to use their memories more efficiently. According to the one-year agreement, deliveries are scheduled to begin immediately.

James G. Turner, chief executive officer of Dense-Pac, said the company, based in Garden Grove, also plans to introduce a new generation of stacking products later this month.
