Tha later versions of poseidon stack Does not work with the mediator card. Perhaps that is the reason for the yellow guru ?.
As I understand it for now there is only clockport USB hardware to buy (dont counting the Elbox spider).
Sad problem that Chris Hodges and Elbox went to war, Even that I feel that Hodges is doing the right thing to protect his product Poseidon. Even Worse is that other programmers supporting the war and end their work on mediator support.
As for now I do not know any other PCI busboard that works with the A1200 So it's really a problem for the Amiga End User.
