Synchronous programmable sequencer (SPS)
Abstract
The purpose of this document is lo provide the user, the maintenance engineer, and the system programmer with the necessary information for its maintenance and use. The document provides more information than would normally be required by the average experimental user. The latter may want to limit himself to reading the following "Short. Description" and taking a quick look at the rest of the document. The SPS has been implemented on a Harris universal interface wire wrap card. This card, bought from Harris, contains all the interface element’s needed to communicate to and from the computer. They are mounted in wire wrap IC sockets and wired lo their respective pins in the channel communications cable connectors. Since the card also contains a number of 16 and 14 pins wire wrap IC sockets, the SPS logic is implemented here by populating these sockets and interconnecting them.
