Well best way to snoop in is with the help of (Win)UAE. Shouldn't be so hard since you should have some legit OS-copies.
Just imagine a miggy running at 1GHz or more (depending on host-CPU) at no extra cost.
The AmigaDE is nothing Amiga-related, just something with "the_Name"-badge, and has been at a complete standstill for ~3 years.
Their are also 2 attempts of creating "next-gen-Amigas", both utilizing a PPC on PC-like mobos. Nothing in the HW that is Amiga-related (and most would argue that as a good point :-) ).
The Pegasos is rather expensive (299-499Euro for just the mobo) has on-board sound FW, GBit-net,USB ..... and uses DDR-RAM.
All fitting onto MicroATX. Comes in G3/600 and G4/1000Mhz.
The A1 is insanly priced (sorry no other way to call something starting at ~800Euro) lacks sound, FW and the GBit, uses SDR-RAM on a full size ATX-board. A 800MHz G4 seems to be the only CPU available atm.
The A1 currently runs OS4-pre-dev (or something like that), while the Peg runs MorphOS1.4.2.
MOS1.4.2 is offer compabilty with all old formats, be it 68k or PPC/68k-mixed(+MOS-native offcourse), while OS4 only support 68k and OS4-native atm. MOS is much faster, both running 68k and native SW, is more stable, but lacks a few extras (all of them can be taken from Aminet or similar). OS4 still struggles with a non-JITed EMU and some system-components in 68k, but it also features lost of stuff that was taken from OS3.x plus a native TCP-IP-stack.
And now await both sides coming in and telling you that this&that is allready in beta for the OS of choice, but those should be safely ignored, since rule No.1 in Amiga-land is:
Something that isn't available for joe-6-pack does not exist !!
A bit cynic, but that will help you very much if you decide to stay here :-o
There are also Amithlon and AROS for X86,but the 1st isn't available anymore :-x while the 2nd is still faaaaaaar from being useable.
But as I wrote, better stick with UAE for the time being.
