I'm after two things.
First would mean NEW Amiga stuff ... and since the AmigaOne Sports the most standard-interfaces, this is more a problem of software.
"VINTAGE" things:
I have been after a Viper 530 / 50 MHz for some time now, without avail. It does not really fir my needs anyway, too much things on the one side (interfaces), too little on the other.
I dream about the final 68k-socket *accelerator*.
- 68030 or 68040 @ 50 MHz (maybe 68060, but I doubt that it would fit in an A500 or A1000)
- Using standard SIMMS (up to 128 or so)
- FlashROM, like the Blizzard TurboMemory board had, but it should either keep the ROM image after power-off or use the actual KickROM of the Amiga. Would save lots of money for 3.1 ROMs or would maybe even enable a 3.5 ROM?? Main advantage would be to have the KickROM accelerated!?
-68000 fallback mode with memory still enabled
-clockport (like the adaptor from Katodev was going to offer).
- an AGA option??
And of course, it should all fit into a A500 AND A1000

Thats it basically

Oh, and by the way: I am not after a PPC accelerator for the classics. I'd be rather after the coldfire accelerator... if only one was made to fit in the Sidecar!!
Thats what I am after.
Good luck,
