QITNCR Hardware ca. 1997Quad Interrupt Controller - Resident on the Quad processor board and is designed to provide enhancements to the VIC to allow greater than 8 processors. One or two processors on the Quad board are configured as Extended VIC Processors and receive interrupts from the VIC. Thus the VIC routes interrupts from the I/O board (or other source) to the QIC and the QIC routes the interrupt to one of two processors on the Quad board. See the Quad Interrupt Controller (QIC2) Functional Specification for details.

We don't guarantee absolute correctness.
Please understand, we cannot guarantee the correctness and accuracy of the information presented here.
We will make corrections, if warranted.
To send additions, amplifications, suggestions and/or corrections, click here.
We will present clear expansions.
For most acronyms we give complete expansions. However, it is sometimes more helpful to define an acronym or buzzword using other acronyms and buzzwords. In the latter case, we will include in this list all the acronyms and buzzwords used in the definitions.
We will be original.
We eclectically gather information for acronym expansions, explanations and keyword definitions from multiple sources on the internet, many technical publications, dictionaries, encyclopedias etc. and then render our understanding in our own words. This acronym and buzzword list was originally inspired by the NCR Global Support Center Case Candidate Knowledge Page (ca. 1996) ID#: DAYH0100012402
Trademarked names are implicit.
We display some well-known (and obviously) trademarked names without marking them as such. We expect the reader to recognize these as trademarks.
This list is always under construction.
We will update and modify this web page from time to time at irregular intervals.
