In use today?

are these protocols currently used? --Anonymous

Indeed so, in the test and measurement field (for comms between oscilloscopes and PCs, for instance). It is most commonly known as GPIB in that role. I don't think IEEE-488 is used (to a significant degree) for comms between computers anymore. --Wernher 19:33, 26 September 2005 (UTC)[reply]

topology

I don't have time to locate sources for my information, and I work for a company with an interest in this technology, so I won't edit the main article here, but...

IEEE-488 is not limited to daisy-chain topology as stated in the article. The allowed topology is essentially arbitrary, with limits on the total length of cables (due to capacitance) total number of devices (due to capacitance), maximum length of each individual cable, and number of connectors stacked on each instrument (probably because stacking more would create a lever arm that could physically damage the instrument if pushed on).
