1. The power relays on the switching board 7140 are triggered via the internal, parallel interface.

2. The first was parallel SCSI (also called SCSI Parallel Interface or SPI), which uses a parallel bus design.

3. Another internal 32-bit parallel interface was used for the coupling the 8-bit to a 16-bit microcomputer card.

4. In this paper, we introduce a system of real-time control of traffic signal lamp, which is designed using programmable parallel interface device 8255A, interrupt controller 8259A, and 8088CPU.http://Sentencedict.com
