Yeah right... NOT. An FPGA large enough and fast enough to have a 50MHz 060 would cost $$$

If the goal is to run os/4 then the far easier solution is to get os/4 to run on old ppc Macs.  Not easy, but far easier than trying to make an eight layer board from a grainiy image for the top...

Make a PCI card for the NatAmi60 that can hold 16 Gigs of ram.

Is the PCI address space even that big?

[SamuraiCrow]

No, the Natami is 68060 based and therefore only addresses 2 gigs of addressible fast ram.

That's why Atheist wants it as a Ram disk.

A 16gb ram disk would be _sweet_. But as long as we're dreaming, why not make it accept 4gb modules, and take it all the way up to 64gb total?

[Atheist]

SamuraiCrow is correct. AOS would see is as a hard drive in a PCI slot, but it's made of RAM!

This could be usable on ANY computer even Macs and pcs and even AmigaOnes, big market potential. Since you CAN'T turn off the swap file on an XP (it won't work right anymore, it is pure garbage), then people would want to use it as swap space!!!

Since it's really a hard drive controller, you could put 2 compact flash card and 2 SD ram card sockets on there too.

IN FACT, if you make it with 4 compact flash card sockets, and create a RAID circuit, so that every byte read and written is spread across the 4 CF cards (nothing to do with the OS, the OS thinks it's writing to a standard IDE device), then you could get a throughput of 4 cards * 266x transfer * 150,000 bytes (base flash card speed) a second = 159,600,000 Bytes per second!!!!!!!!
159 Megs a second transfer rate, sustained, can hard drives go that fast?

State that 4 CF cards must be on it for the controller to work and they all have to be the same ram capacity.

Hi pkillo,

I'll tell you why not, because I didn't know they make 4 Gig ram modules. ;-) :-)

I heard that there are 2 Gig ram modules, though. Never seen them listed.

The whole idea is that he's dreaming--IE like "i am"

He's dreaming of 4GB modules, like I'm 'dreaming' of new accelerator cards

@Atheist

Before posting I would urge you to read up on the 21st Century... despite nearly 10 years, it seems to have totally passed you by...

First off, I never have to swap file switched on on my XP machines (they all have over 1gig ram...).

Secondly... wander over to a local Computer store and check out the latest USB Flash drives... I have two 16gig OCZ Rally2s sitting on my desk right now... they only cost me £35 each...

Finally... a 2Gig DIMM can be bought from any good computer store, I bought a 2Gig Corsair DD2 SODIMM  last week for my MacBook Pro for £29 from http://www.dabs.com

Hi bloodline,

I'm not sure if I have service pack 1 or not (and I don't have 2), but, when I turn off the swap file, it is IMPOSSIBLE to install EverQuest.... It just would not install and there was no g DAMN explanation given to the USER (that's me) as to WHY it COULD NOT install!!!!!! (It probably would have been IMPOSSIBLE for a MS tech, through e-mail, to figure it out, too!)

Well, if you're putting 4 in, and remember, the highest rated costliest types, it gets rather pricey. I was thinking, you put the most essential things in there, like the OS and EverQuest.

Isn't it much cheaper to buy 3 1 Gigs?

Now that I think about it, I think I saw it in a computer store once, but thought the clerk made a mistake describing it.

Also, you STILL need a 1 Gig to get to xps limit of 3 Gigs.

Funny that, AOS came out in 1985, with a 2 Gig limit and billy gates, in 2008 has a mere 1 Gig ram space edge over us!!!!!!!!

AND, their OS uses up almost all of the extra 1 gig, so we're STILL ahead!!!!


NatAmi60, 512K of OS, 270.5 Megs free!!!!!!!!!! Woohoooo!! :-D :-D :-D :-D

AOS would see is as a hard drive in a PCI slot, but it's made of RAM!

It would not. No drivers.

big market potential.

lol

That's huge load of nonsense. First of all you can turn the swap off and it works just fine. Second you would obviously put the memory to the mobo directly, rather than going thru dead slow PCI bus.

But hey, tens of GB/s isn't as impressive as 159,600,000 Bytes per second!!!!!!!!

[Piru]

You lose dual channel for 1GB of memory then. Bad. 2 x 2GB is much better idea, even if you lose the 1GB due to 32bit OS.

You're living is some parallel universe. 64-bit vista can handle 8GB (home), 16GB (home premium) and 128+ GB (the rest).

In 32-bit XP, the 3GB limit is actually hardware one. Windows XP itself could easily use more.

Hi Piru,

Where? On an XP computer? The PCI CARD would have the logic that separates the data to the separate CF cards, and rebuilds them before sending it back to the computer in a read.

On the NatAmi60, they're making PCI drivers, and to the computer, it would look like a NORMAL IDE controller. The OS does not need to know the data is being written across four CF cards.

You're so negative! It's easy to say that when they're NOT available.

EVERYONE would want one!

As described above, MY xp computer DOESN'T work with the swap file off.

Do you have EverQuest? Try what I did.

Don't you understand what I wrote? It's a HARD DRIVE made of 4 CF cards..... Not main system ram.


And the NatAmi60, unfortunately won't have more memory slots,.... wish it would. :-((((

Hi Piru,

On the Amiga 1000 in 1985, it was a hardware one too!

NORMAL IDE controller doesn't work either. No drivers.

Hard drive keeps its contents over power off. What you're proposing is a not a hard disk, and it has absolutely zero benefit over system main memory.

On the Amiga 1000 in 1985, it was a hardware one too!

But AmigaOS cannot use more than 2GB, even though the hardware would allow it.

You can already buy these, Essentially SATA caddies that take CF cards... the performance is less than stella... Just buy an SSD...

Honestly Atheist, why do you bother posting on technology issues, with no technological knowledge?

Hi Piru,

Huh? It's using CF, compact flash cards, all the contents would still be there the next day, you can boot up off of it!

I think sane people would ONLY choose an Amiga capped at 2 gigs of ram over xp capped at 3!
