Cards let a PDP-11 work like a VAX

The PDP-11 computer is still used widely, in part because of its many peripherals and software applications. For less than $7000, a new board-level product from American Information Systems Inc. promises to give the PDP-11 renewed life as a dual processor based on a UNIX-like operating system with more power than a VAX, its younger superminicomputer cousin. National Semiconductor Corp's 32032 is the foundation of the AIS/3210 system, which also includes a national 16082 memory-management chip and a 16081 floating-point-processor chip. One or more processor boards and memory boards from AIS plug directly into a 16-bit q bus.
