Home grown A1200 accelerator project

OK, here's a crazy thought:

A CPU accellerator board with an Intel CPU.  Before you all start kicking and screaming, let me explain.

The whole thing should behave like a 68060, because it's basically a CPU emulator.  No Intel instructions are available from the Amiga.

The board also holds 128MB RAM which behaves like the fastram, and is accessible at the board's local bus speed.  The chipram, located on the Amiga motherboard, will be as slow as before.

So, picture a 4 GHz Intel CPU doing nothing but 68k emulation.  No Windows hogging resources in the background, no multitasking.  Just one mission: Emulate the 68060 at full speed.

I would not be surprised if something like this would measure in the neighbourhood of a 7-800 MHz.  Only stuff in fastram would truly gain from this, but still - things would be *a lot* faster.

Hell of a project, though.

Wow.  You had the exact same idea, nearly exactly one year before me.

What are the odds?

Rom wasn't built in one day.

Yeah a bicycle with a turbine can be really fun... but most people will be annoyed seeing it. Maybe take a less fast (and non intel) CPU for a "Classic" add on?  :-D

I think the phrase is not "people will be annoyed seeing it", but "the rider, along with the bicycle will experience a serious melt-down" :-D

OK, back to dreaming...

Sorry old link broken ...

You think only in 2 dimensions.

If you want to think as MiniMig as an object then yes, the MiniMig v1.1 PCB isn't very good.

However the IP behind MiniMig is open source, any hardware engineer capable of creating an Amiga product of any complexity (with an ounce of buisness sense) is now thinking MegaMig. They are not thinking A1200 accelerator.

This is also opensource ..
Still work in progress, but lets think about a combination of zorro and minimig.
Nearly all signals are present ...
MM2000 ?!
