I see that fewer and fewer things remains to be hammered and that the team is close to the target.

Close to the first milestone which is having a basic system which is running well. Most extensions are about to come. Unfortunately, the closer we get to the first milestone the more details appear out of nowhere which want also to be considered. michel michel3105 wrote:

I'm extremely curious about how the blitter will shape up, in terms of usage and, of course, performance... :)
|
Even the current blitter is already faster than the one of an original Amiga I would guess its performance to be about 15 to 20% of the final goal. - This is "work in progress". I guess there will be a few iteration steps of the blitter.

One of the following tasks is to move all the DMA channels from 32bit to 64bit data width. But this needs to wait till I got the whole LX design running on the MX board and the PCI bus communication is established. PCI is needed for the Flash-ROM, IDE, CF, LAN and USB.

Do you finish the work ? Some lecture about the design of and ram centric architecture of Amiga trend : EXTERNAL LINK
Thank you for the update to come...

| The M68K was a hybrid CPU not a von neumann design.
Besides that using two types of RAM spaces makes it look like a harvard design.

Well, at least the DMARQ and DMAACK- are connected in Natami. So this can be implemented. But I think it is not directly related to these Signals. What I see is, that the problem looks a little different:
A Recalibrate Command causes an interrupt (the first interrupt from that device in the system). The interrupt handler then reads the status register. But, it does not turn off the interrupt as it should. And so the interrupt happens again and again forever. If someone has more info about this please start a new thread.

Compact Flash memory card working
It took a while to test it. But now I can confirm that the Compact Flash connector is working fine. With this connector it is possible to plug a CF Memory card into the system, write a RDB on it and use it as a (fast) harddrive.
To be able to do that the CF Card needs to support "True IDE" mode which makes it behave like an IDE harddisk. Unfortunately not all available cards on the market support that mode. This is the same problem as you have on a standard Amiga. Maybe in the future with some effort I can circumvent this problem.

1 month later :) Any more news to share ? No matter how small.
Saw a post on the team part named number 9 so i guess there are soon 10 Natami in the wild :D

Still working on real updates. Till now I had to solve intercommunication stability issues between the logic chips. There were logic as well as timing related things causing glitches in IDE port and the external peripheral output lines.

Ill offer the Natami10 when the Natami9 is soled... Hopefully I can have two or three boards ready in a while. I am preparing some layout changes for a slight larger (and automated) production run. But launching that would take at least till January.

| Maybe a bit late to comment(I thought others might also notice)
The CF card was rotated 180 degrees, do not wake remove CPU card, if you want to change CF.

Thanks for that mini update. Sounds like everything is progressing nicely. 2012 the year of Natami :D

A possible solution could be something like this product:

When the 68050 softcore is completed you can run the Natami without a CPU card.

| On my Natami I use this CF to ATA adapter, to
easily access the CF module, without having
to remove the CPU-card:EXTERNAL LINK
But remember: all the onboard slots are not really
designed for hot-plugging. Also be aware that you
would need to find a case with an opening just for
the directly onboard connected CF - which is very unlikely. A much better solution is to use a Usb-stack
with usb2cf adapter or your favorite flash-media
as removeable!

| How does the CF adapter work? Presumably it's a female - female which wouldn't work :) How do you convert the Natami end to a male?

If you had followed Peter's link, you'd see that it plugs into the PCI slot. It doesn't look like he's using the on-board CF card adapter yet.
