AGP bus expansion for Amiga?

[Duce]

Outside of the SAM boards, there's no point in even having AGP, because there's no way an Amiga CPU would even come close to using AGP levels of bandwidth.

No AGP on my SAM or on any other one I've ever owned, used or seen.

USB is crap because:
 * Uses polling rather than letting devices tell when service is needed
 * Half-duplex with associated latency, superpositioning wave amplitude, speed and predictibility problems etc
 * Use of single ended signaling for out of band signaling
 * Hierarcical structure enforced, more complicated than a bus option
 * Single master (OTG is patchwork)
 * Limited to 127 units
 * Insufficient power 2,5 W (vs 45 W for firewire) which makes 3G dongles etc out of specification
 * Lacks galvanic isolation with signal transformers, like Ethernet is designed

ISA was in essence replaced by USB because they are on the same performance level and both serves as "geekports". PCI (and MCA/Zorro) are something completely different with autoconfig, wide bus, thought through transfer phases etc.

LOL, just LOL.

Dudes, the best tech rarely wins,  if it did, the Amiga would be thriving.  What it reads as "on paper" means absolutely nothing to Joe Digicam.
My Mum doesn't give 2 ****s about the limits of 127 devices, voltages, or polling with USB.  She wants to plug her camera into her computer, her printer to her Mac.  It works, and that is all anyone cares about.  Anyone that requires better solutions has been using something better suited for YEARS.

USB is ubiquitous, love it or hate it.  Joe Printer can plug any device in via an easy to use cable without blowing crap up, and that is all that matters.
People that require higher performance have many other options.

Doesn't matter if they chose the lesser, inferior technology - it's ubiquitous, commonplace and easy to use.

SCSI was superior to IDE, and IDE still won out in the long haul.  Joe Lunchpail found SCSI ID's and terminators confusing compared to a simple master/slave jumper.

In the world of commodity devices, the best solution rarely wins out.  The common man uses what works, the power users have more suitable options.
I'm no fan of the slow speeds of USB, but I've never had a lick of problems with USB devices, even on my Amiga systems.

Absolutely nothing wrong in the least with other tech that isn't necessarily "the mainstream".  If it works, use it - but let's not discount the ubiquitous standards as "bad".  USB has served billions of people for 18 years very, very well - if it was inherently crappy, it would have went the way of the dodo long ago.

Hell, I own a '32 Ford.  I love it to death, for what it is - but at the end of the day, if I have a 2000 mile roadtrip to go on, it's my SUV I'll be driving, not the '32 Ford
