What is a firewire cable for a mac for free#

particularly Intel which had sunk a lot of effort into 1394 (the improved 1394a-20b-2002 standards are partly based on Intel work). This annoyed everyone (including yours truly) immensely. I left Apple before Steve came back, so I have no idea how this really happened.

What is a firewire cable for a mac for free#

you could get it for free if you just signed an agreement to use it *only* for a product that was compliant with IEEE 1394-1995 (the original version of the standard).ДЄfter Steve Jobs came back to Apple, he was somehow convinced that Apple should change the game midstream and ask for $1 per port for the Apple patents (his argument was that it was consistent with the MPEG patent fees). Under that agreement, the IEEE agreed to include the appropriate patents in the standard.ДЄpple never intended to charge for the use of the name 'Firewire'. When Apple was participating with the IEEE p1394 working group (I was chair *and* Firewire technical lead), we proposed licensing all of Apple's blocking patents for $3k, one time fee, and only for 'the point of first use'. I'm sure there are others, but those are the primary ones.

Alistair Coles and others at HP Labs (Bristol, UK) invented the encoding methodology that allows 1394b to run so fast and still meet FCC class B emissions specs.

David Wooten and I enhanced this a bit to make it run at optimal speed regardless of network topology.

Jerry Hauck and David LaFollette (both at Intel when they did this) invented the 'BOSS' protocol used in 1394b and 1394c to allow bus arbitration to proceed in parallel with data transfer.

This allows roughly twice the data transfer speed over traditional clock-and-data interfaces.

Paul Walker and others at ST Microelectronics invented the data-strobe encoding system used in 13a.

David is currently an independent consultant. something that the rest of the world is finally catching up to with something called 'RDMA' (remote DMA) used in the iSCSI universe. David was also the one that pushed to allow Firewire to act like a memory bus, which was the key innovation that allows Firewire disks to be their own DMA controllers.

David James, who, along with me, invented the isochronous access method that allows Firewire to simultaneously transfer streaming data (audio and video) along with low-latency asynchronous data (disk data, IP networking, etc).

Bill is currently working with Roger at RF Microdevices. Bill further enhanced the protocol which resulted in the major technical enhancements in 1394a.

Florin Oprescu and William Duckwall, who invented the arbitration and initialization protocol used in 1394.

Roger is currently at RF Microdevices and Florin is at Linear Technology. Which indirectly led to National Semiconductor's creation of the industry standard 'LVDS' (low voltage differential signalling) interface in the early '90s.

Roger Van Brunt (Apple) and Florin Oprescu (Apple), who did most of the work on the original transceivers.

(See the brief history below.) The primary people (besides me) include: There are many people and organizations that worked together to 'invent' Firewire.
