Hardware News   Hardware News : TAM EXCLUSIVE! Individual Computers Reveals Clone-A Project
   posted by rhino on 11-Oct-2006 7:59:51 (10909 reads)
In an exclusive interview with Total Amiga's Magnus Johnson, to be published in issue 25, Jens Schoenfeld reveals Individual Computers' latest project. For the last year Jens and Oliver Achten have been working on a cycle-accurate reproduction of the Amiga chipset in FPGAs under the codename Clone-A.

Jens and Oliver will be demonstrating prototype versions of the Clone-A chips mounted in a real A500 motherboard at the AmiWest show on the 21st of October. To prove the compatibility of the implementation, even in its current form, Jens encourages show visitors to bring along A500 compatible disks to the show to try on the Clone-A.



As Total Amiga 25 won't be out until after the show, we have published an extract from the interview in PDF format. The extract describes the Clone-A in detail, traces its history and explains the current state of development. Jens also looks to the future at the possible uses for this technology once it is complete. Included in the PDF are detailed photos of the FPGA development boards. The extract PDF is a free download from the Total Amiga web site:

Or better still on a PCI card that can be run on any machine... or have I missed the point?


Well, since we're all just wildly speculating, there's not much of a point anyway.
But we're talking two different things here... a itx board for standalone Amiga Classic clones, and a PCI board to live in a peecee or some PPC New Amiga. I'm not sure about having a PPC or X86 access the 'custom chips' just like a 680x0... sounds like a lot of work. I think a better notion would be to have a real 680x0 or an FPGA core on the PCI card... Sort of make the card an Amiga classic bridgeboard, reversing the roles so to speak. Then map the entire memory space of the Amiga into the PCI memory space.

[crazy insane talk]
Okay, so, OCS/ECS AND AGA!!!!!

You can pick how the FPGA sets itself up at boot time.
The FPGA is loaded from flashroms on the board.

OCS/ECS is emulated at standard 7.12 MHz, and AGA at 14 MHz for total compatability. Higher speeds to max available FPGA can do, selectable. i.e. fake 20, 25, 33, 40, ... MHz.

It's a PCI card so "two" computers are there at the same time.

AOS4.0 and AOS1 through 3.9 communicate through fake VCN (is it? or whatever is best) connection across the PCI bus.

Either a monitor is connected to the PCI card, and/or, click on an icon on AOS4.0 workbench to go to AOS1 to 3.9. It comes up full screen, or as a screen under workbench, just drag/click through to it.

Rebootable from AOS4 or it's own screen.

Chip ram boosted to 16+ Megs.

Can connect monitor, kb, mouse, joystick to PCI card. (dream mode ser., par.) Then it could be fully independent to do other tasks.

Atari ST/FM "mode". Oh, oh, then it would need a MIDI port. Something all Amigas should have come with!!!

Imagine the MIDI being usable from the Amiga, too.

Oh, oh, oh!!! Imagine being able to load a game into flashrom (say 16 Megs), and booting into it!!!!!
[/crazy insane talk]

Hey BigBentheAussie, and you thought YOU were a fanboy!!!



Only Amiga makes it possible!!!!!!!! < < < ---- NOT crazy insane talk!!!!!!!

Hi Tomas,

Oh and, "you'll never need more than 640 K"!!!!!!


Remember how BEAUTIFUL it was plugging in more ram, and it's just THERE!!! Magically.


Then there was, remember trying to get mice to work in dos programs!!!! Hahahahahahaha!!!!!!

I have a mouse here somewhere from the time of windross 95. It said I should have 30 megs of HD space for it!!!!!!!!!!


I'm sorry, Amiga was "IT".

@GW :
It was Bill Gates, now he may try to detach himself from saying that, after all it doesn' make him look good, now does it?

Are you seriousely suggesting that the a500 was outdated in 87?


But the Amiga 1200 was seriously outdated by the time it was released:

Quote:

AGA does not add very much to the design size. Since the blitter and the complete Paula chip stayed the same, we’re only talking about 27 instead of 25 DMA channels and a local bus performance upgrade by a factor of four. That’s something we can
easily accomplish with the type of memory and the logic chips that we’re using. Remember that we’re talking about a machine that was up-to-date in 1985.
According to Moore’s law, AGA performance should have been reached 36 months later in 1988.

I know, that's why I linked to Wikiquote:
http://en.wikiquote.org/wiki/Bill_Gates#Misattributions

Until I see a credible source that he actually said that I will consider that "quote" as a misattribution.

But "only the paranoid survive" is a real quote:

I just wish that the heads of Commodore had listened to that advice in the 80's.

You know I went back and took a look at the actual article, and that is something I can get behind. I didn't realize the A500 thing was for demo purposes. A reengineered Amiga but with, say, 8mb chip and PCI slots is what I was hoping for and maybe, just maybe we'll see something like that.
