I've got to disagree with you. This coldfire board if it ever materialises would be the bees knees:-) I've got a brand new Amiga 500 here I would drop one in:-D

Me just bought an  A500-Plus, so i'd buy one too.

Anyone know if 3.1 ROMS are available/usable in one of these?  If not, which is the latest version to work in one?

So 3.1 roms plus a coldfire 220 would make the a500+ a very nice machine indeed.  What about IDE support? Is it possible?

There are some crappy aftermarket IDE adapters available, and there are some homebrew hacks on Aminet. A SCSI adapter would be preferable.

Of which, your personal reccomendation would be?

There are things to consider. If you don't mind ugliness a sling shot with A2091 would work pretty well. A bogoda bay with A2091 would look a little better. If you don't plan on adding a gfx card(which would be a major hack anyhow), a GVP A500HD would work well.

I am aiming at £170 for a basic A4000 version (USB, IDE, SDRam and 220Mhz Coldfire) however it depends on lots of things so it could go much higher, specially as a lot of people want Ethernet (10/100) as that isnt cheap.  


So how much more would it cost to do a whole motherboard? :-D

By the way, I was thinking about putting a pegasos into a cdtv case, any thoughts here?

Two questions...

1) What's the fastest coldfire cpu available that would be feasable in an accelerator

2) What sort of missing instruction emulation will be used? Hopefully something like oxypatcher / cyberpatcher...

I think it's a cool idea. I might have to pick up a 2nd hand a1200 just to kit out with one :-)

Hehe, to much  :-)
Anyway apart from the Amiga 4000 being an old system its the best design for the Coldfire CPU.

Naaa, Put it in a microwave, that looks much cooler.  ;-)

A set top box Pegasos would look like a nice machine though... but what about the PCI cards? right angle adapters maybe?

Well I see no limit that I can see, although the Coldfire can run at up to 333Mhz it has a bus speed of only 50Mhz. (actually its selectable but thats what I am running the prototype on)

Nope, its got to load before the Kickstart so you wont see it running at all.
Information can be found at http://www.microapl.co.uk/
 (They also do a 68K emulator for the PPC as well as programs to port 68K assembler to Coldfire native code.)

Cool :-)

Anyhoo, I meant hopefully the emulation works like ocypatcher - ie patching instructions rather than trapping them every time :-)
 - my fault for being a bit ambiguous...

...well, I am a moron after all ;-)

Does this project make any sense anymore?

Now when amiga has migrated from 68k and legacy hardware coldfire doesnt seem to be attractive.

Its not as powerful as ppc and none of the new amigaos-flavor os-es will run on it.

I classify it as hardcore geek toy :)

@porneL

Ok, look at it this way. OS3.9 will be around for some time after the launch of OS4. Kitting out older systems for which PPC is not an option with a CPU capable of 300MHz 68K operation with pre-OS4 isn't a bad idea :-)

Even if I could afford an A1XE, I'd still like one of these to play with :-)
