A500 ++ Prototype

I appreciate the enthusiasm but can't understand why they don't go AGA while they're at it...

Looking at that image, it looks like the OCS/ECS chips are to be transplanted from an existing A500/500+. That's not quite so easy to do on your AGA A1200 where the custom chips are all SMD.

No reason to do a whole new motherboard if the new motherboard doesn't offer you any benefit over the old motherboard + an accelerator.

How about improved reliability over an old A500 motherboard/accelerator card combo?

Maybe the motherboard is made because the 68000 is 16 bit and a 68030 is 32 bit ?!

If it's using the original (O|E)CS chips then presumably only the local 030 fast RAM will be 32-bit and the path into the chipset 16-bit. In that respect, no different to an accelerator.

However, that's an assumption. I don't know that they aren't going to use some FPGA solution or other, but there sure are a lot of sockets on the board.

:lol:

I guess the guy just doesn't know how PATA (as it's now called) works

@Amiga_Nut

PATA is 16-bit. Always has been and now that it has been superseded by SATA, always will be.
