The limitation is in Alice. It might just be lack of support in the chip, but I've never bothered to look whether the pin out would support >2mb. It's a dram interface so row and column addresses are multiplexed, it's not as simple as counting address bits. Bearing in mind the a4000 2mb/8mb chip jumper, it's possible that if you could obtain an Alice that supported 8mb it would drop in to the design. It might need different ram though.
 
 It's possible but unlikely that Alice would support 8mb but the motherboard and ram that commodore supplied was unsuitable. I'm not holding out any hope that anyone would find out how to make that work, even if it did exist.
 
 The only way to fix it would be with an FPGA and then you might as well buy a mist or arcadefpga.


Just need to look at how DraCo did it :-)

No, always ask: "Hey! Who the hell drank half my beer?!?" ;)

From Jens perspective it makes perfect sense to have no CPU, its a new board, that sells more of his boards and it *might* work with older accelerators too. Likewise with the USB etc.

Really he's not going to be able to please everyone and this "buy what you want" approach makes sense.

I'm certainly curious about it anyway.


Yep have to agree. I'm sure it's been carefully thought through. With the eclectic mix of Amiga enthusiasts around these days keeping things "open" is a way to cover most bases.  The purpose of the card is to provide updated hardware. (The old stuff wont last forever.  Accelerators included)  This way an Amiga enthusiast can have new hardware with new components (including caps ;) ) that will last another 20 years.  By then..  Well..  All good things must come to an end...

Is there a way to produce more AGA chips? Were the digital files / ic chip mass production data lost forever? The machines were produced up until 1996. Why are these 25 year old chips so hard to source?

Because they haven't been manufactured in 25 years?

A Draco clone would be cool and a mini-mig in a 3.5 inch FDD bay sounds cool too.
I have been looking at the older modular bus systems and a back plane system sounds like fun.

I sort of agree with the modulat approach, since it will be up to the end user to add modules he or she wants.
But I do not see the point in using old chips, with old speeds, since all the chips can be replaced with fpga, we could have aga compatible chips, high speed and with 32 bit capability. But then again, the Overload board can be build now.

Jens can probably replicate or even improve upon the AGA chipset, so I'm a little confused by this design as well.
But it will probably be the last run of boards with real Amiga hardware.
So  I may have to consider one myself.

Right.. who knows. Could it be that once the finite amount of Amiga chips run out he will then become the solution to the problem created by selling off all the remaining Amiga chips. Jens can do this by finishing and releasing the "clone A" chips as plug in replacements for use in Amiga Reloaded and all Amigas.


At any rate hope this comes out.
