in 2011 with PCI slot widely avaible through Mediator, G-Rex, and prometheus, we shouldn't
look after old Zorro Cards, the reason why we wanted PCI was to use cheap and standard hardware. I don't want to buy Spider or Radeon from Elbox, I just want drivers.

But the project is a complete mess. No driver, no 3.3 volt power, moreover they let good programmers like Hodges go away preferring to talk about some vaporware that will never see the light (Dragon?).
Bad company :-(


Hmmm...

Zorro bus > Zorro USB card
vs
Zorro bus > Mediator > PCI USB card

methinks the KISS principle applies ;-)

Deneb is by far superior imho (and personal experience of both cards in A4KT). The lack of real DMA offered by the mediator cripples any chance of getting 'better' performance (faster transfers, less cpu overhead, etc) out of a PCI USB 2 card.
A lot of work (of which we were very well informed in the forums) went into the development of Deneb, including working around the various issues relating to different versions of Super Buster and testing with combinations of the (few) other cards which take advantage of Z3 dma.

@E3B
It truly was amazing to read the development given the lack of documentation available (15-year old proprietary chips of a dead company, etc), and set a high watermark of hardware development and testing for the classic Amiga platform. My hat remains off to you to this day.

@Chris - nice to see you back in the forums, I don't come to A.org that often these days so didn't realise you still posted here.
