Aos 3 -> aos 4

If your Classic Amiga has Zorro III you can get USB 2.0 with the Deneb card.  It works with the Poseidon USB stack under AmigaOS 4.0 or 4.1 Classic.

But obviously due to the limitations of Zorro III (and even worse Zorro II) you won't get anywhere near the 480Mbps of USB2 high speed.

And Deneb won't do DMA on OS4 due to OS4 incompatibility/limitations dealing with perfectly fine DMA OS3 drivers.  BlizzardPPC/A4000T scsi situation is worse because it won't work at all.

The hardware is ahead, the OS is behind and far behind too.

At least AROS has a proper USB2.0 stack and better driver support (2D/3D gfx cards, better WiFi support)

Better performance than any classic machine and the price is what you would expect.

Better performance than a 50Mhz machine... wow! amazing! wonderful! let's bring more popcorn! We would seriously have a problem if performance/price ratio wasn't much better than 7 years ago... what? did I hear you say Pegasos2-G4/1Ghz for 500€? nahhh I'm sure our wonderful 2011 brand new boing ball hardware is way faster and cheaper than that 7 year old hardware released in small batches :-P
