Prime (also PR1ME) was yet another minicomputer company founded by ex-Honeywell employees, some of whom had worked on Multics, an early timesharing system.
The firm’s products reflected its roots: they were clones of Honeywell computers. But the Prime 300 in 1974 added the paging hardware necessary to support timesharing, which was unusual in a minicomputer.
Bill Poduska, Prime’s lead technical founder, tested the original concept for the Prime 300 at a NASA lab in Cambridge, Massachusetts, modifying a Honeywell DDP-516 to add paging hardware needed for virtual memory.View Artifact Detail
Banking on Computers
Bank trust departments once relied on bookkeepers wearing green visors to crunch numbers. SEI Corporation proposed changing that by providing bank officers with desktop terminals linked to SEI’s Prime 300 computer in Philadelphia. The computer would crunch the numbers instead.
After Wells Fargo Bank signed up, sales took off.
