Of course. However, port to another CPU architecture requires massive investment, if you want maintain backward compatibility.

@pavlor

that discussion is OT of course

you can integrate 68k by UAE, you have a problem when wanting something like Petunia and when you want to run PPC software transparent. Both would need lots of work to do.

Why cannot this community agree on a common hardware that is something that will bring amiga forrward but on the same time will bring new tech to the amiga like usb, ssd, 32 bit color, etc.

But on the same time is in the form factor that is possible for everyone to own with prices that is NORMAL!.

Once you have USB 3 port on a motherboard and data sheets on how to make it working, then it should be trivial to make a driver for it.

SSD HDisks have SATA interfaces and Sata works flawlessly on SAM 460 and AmigaOS.

32 bit color is already available AFAIK... But actually AmigaOS and MorphOS cannot access VideoMemory RAM of Graphics cards more than 128Megabytes, due to obnoxious legacies.

Okey let me say it like this.

Most of us now use a amiga as a secound computer, ok. ?

So how can we produce some hardware that still is a classic amiga but will bring us forrward that will be something that can be a entry level amiga. ?

Delusional conspiracy theories aside, I would like to point out that close to 12.000 USD had been donated to the Odyssey and Directory Opus bounty projects... Both received substantial contributions from individuals using AmigaOS.

among others i did. and it has paid off. contrary to some known cases elsewhere.

@OldFart

I don't quite understand parts of this, such as b). Do yo umean something sortof like a modular/stackable riser card, perhaps parallel/in-plane with the motherboard rather than at a 90 degree angle to it?

I don't understand e). 2d? Sounds like graphics. Go with a gfx card or MXM laptop graphics card. I'm not sure how serial ports fit into that. I have a t4240 box, and it has two serial ports, so they are not without merit. I believe they both go direct to uart peripheral inside the t4240 itself, and at least one is useful for debug like the serial port output of AmigaOne XE, and I assume like on x1000 debug serial port.

For Mezannine, I like the idea and I'm a big fan of Com-Express format. Kindof comparable to classic Amiga motherboard with an accelerator card in it, which adds local accelerator memory, SCSI, etc. From all the ones I've looked at, COM-Express has the biggest capability, it's essentially a full PC on the mezzanine card, including SODIMM slots not on some other module standards, and the base (carrier) is mostly just wiring to the connectors, and whatever physical interfacing needs done near the connector, and then whatever other magic you want to add in on the carrier. I've seen modules with two SODIMMs, either stacked on the top side (away from carrier motherboard) or one on top and one underneath. Combining that, you could try for three slots if you're crazy enough. I'm not sure if there's enough expected empty space between carrier and mezzanine to stack two modules on top and stack another two on bottom, there may not be enough height there above the carrier to allow that. But at least two modern SODIMMs should be good absolute max capacity for a while, certainly far more than AmigaOS can yet address. DDR3 SODIMMs go up to 16GB each (8GB are easier to find though than 16GB per stick)
and I'm not sure what DDR4 SODIMMs are available or what PPC CPUs do DDR4. (I think a couple do now) Other Mezzanine standards I can think of all seem to require memory to be surface-mounted, no SODIMM or UDIMMs, so no user upgrades later on for the other types.

Exactly.

Which it is meant to be. Sorry for being unclear abou that one.Quote:

The only thing I can say is that you have the clear picture here.

The only question is, is such a construction viable? Due to its 'mix-'n'-match' nature communities way outside our horizon may benifit collectively, created by the economies of scale. Whatever your needs are and your funds reach, there is always a fitting solution available to you. And standard cases can be used as the board mounting holes are already in the proper position.

I'm with Andre on this one, I'd support a power2people bounty.

For some reason Bill Buck gets as much bad press as another Bill we are all familiar with, and most of it is unjustified.

Good stuff.

Thank you. Just trying to be constructive.

I was just looking at my Coldfire evaluation boards, and they are constructed in a similar fashion.

Sure I can't have 'invented' something new.

The more I think about this modularity, the more I'm convinced of it being worth investigating.

If the company is willing to give you the gerber files, you can send the PCB files to any place willing to make the circuit board.

A cheap service is Dirty PCBs.

Perhaps if every Amiga owner put in $1000, you might get enough to pay for the engineering and manufacture of a few prototypes. But I can think of only one or two people that I would trust to make that investment. On the other hand, perhaps if you wait to see how the X-5040 turns out, you can just let someone else pay for the design work (as he's already successfully done several times).

If this was a DIY effort, it shouldn't cost megabucks but if it costs, I suspect it is because they are trying to recoup their money elsewhere.

$1,000 would buy me the software to generate the circuit board and all you need are the files to send to a board house to make a circuit board.

That price will get you software like Eagle, Schematic and Layout modules. For that, today I'd consider KiCad or DesignSpark, maybe Upverter for free and see how that goes, before spending money. Other than that you're probably looking at US$7000 or so for Altium.

Olegil maybe can speak about how careful you may need to be with impedance control. Cheaper is not always good enough. I'm not sure about how careful you need to be with the relevant DDR, SREDES lanes, etc things.

Even if very tight controls are not required, you will at least need to choose appropriate thicknesses for core/prepeg to select your intended impedances, at whatever tolerancing level will work reliably.
