The problem  is that I don't have a mediator.

on the contrary. that is fortunate. because you can now buy yourself a current mediator model with extended voltage supply (i think it is an additional 3,3 volt rail) which is necessary for the sonnet. an old mediator like mine is not suitable for this without modifications.

Actually I have a Prometheus.  It has three problems with the sonnet amiga project:
1)  it would need the 3.3V hack
2)  it would need a hardware upgrade for busmastering
3)  It lags behind the mediator in the sonnet amiga project.

It looks like from the EAB thread that the project creators wanted to use Prometheus originally.....


afaik the hardware upgrade for busmastering was available from eab 's m.boehmer. i think it was tersters release. would have to look up a1k for this. 3.3 hack might be realized with some voltage converter or something, but then who knows if its wort the hassle. not for me, i must admit.

Realtime comparison of Cyberstorm PPC 604e/333 and Sonnet G3/500


overall sonnes doesnt seem to have much edge on cyberstorm, according to your tests. the one signifficant thing is video playback, which differs so much likely because cyberstorm needs to feed data via pio zorro3 to mediator pci bus rtg card while sonnet can use dma to that rtg card directly/locally on pci.

Really makes me mad at the greed some of the people in our community sink down. Privateering is just wrong.


its a free market. why should nyone be required to sell whatever is considered a rare luxus to anyone else who would be showing off with it for a decent price?

Do tell...

the guys are hardware geeks, there are many hardware projects on a1k, but i bet, none that complex. i wouldnt count on that much, not very soon at least.

admittedly there are accels and rtg extensions for amiga, even motherboard replacements, but to my knowledge nothing in multiple hundred mhz signal frequency region.
