SPI Explained

The Farnell website has the best explanation of SPI that I've seen in some time:

formatting link



"Parallel SCSI (formally, SCSI Parallel Interface, or SPI) is one of the interface implementations in the SCSI family. In addition to being a data bus, SPI is a parallel electrical bus: There is one set of electrical connections stretching from one end of the SCSI bus to the other. A SCSI device attaches to the bus but does not interrupt it. Both ends of the bus must be terminated."



That should make it easy for beginners to interface their E2PROMs!

I guess now that SCSI is going SAS they need to come up with a new abbreviation for the original (parallel) forms of SCSI?
