…a system-performance bottleneck, and the 16-bit logical address limitation hampered the development of larger software applications. The article on PDP-11 architecture describes the hardware and software techniques used to work around address-space limitations. DEC's 32-bit successor to the PDP-11, the VAX-11 (for…
