The SAP architecture serves as an example in Digital Computer Electronics for building and analyzing complex logical systems with digital electronics. Digital Computer Electronics successively develops three versions of this computer, designated as SAP-1, SAP-2, and SAP-3. Each of the last two build upon the immediate previous version by adding ...
A line of personal computers based on the PDP–11, the DEC Professional series, failed commercially, along with other non-PDP–11 PC offerings from DEC. In 1994, DEC [ 14 ] sold the PDP–11 system-software rights to Mentec Inc. , an Irish producer of LSI-11 based boards for Q-Bus and ISA architecture personal computers, and in 1997 ...
VAX (an acronym for Virtual Address eXtension) is a series of computers featuring a 32-bit instruction set architecture (ISA) and virtual memory that was developed and sold by Digital Equipment Corporation (DEC) in the late 20th century.
