I strongly suggest to evaluate the buying of a PegasosII or an Amiga-One than to trade in obsolete hardware against obsolete hardware:-D
I don't know the price for this tradein, but my PegasosII serves me also with pci and it runs more or less all pre morphos-software. Even the good old SID V2.01 from my A1000-time works (though with some color glitches). And the speed is :-o :-o
