Another member of the family

Over the years I have been trying to get a hold of other cards which could potentially function as a PPC PCI card in a classic Amiga with mediator. You have probably seen the PMC carrier picture from way back in 2016.

Thanks to the help of one person in particular (you know who you are) the Rapture card was identified as being able to run in a classic Amiga and added by me to the number of cards being supported. This was an easy one to add as it also has the MPC107 chip-set. The benefit it being a MPC7410 450MHz which made the search for a Sonnet G4 no longer needed.

That same person also looked into other chip-sets besides the MPC107 and pointed me to them and their documentation. It took a few weeks to program (effectively...I've been busy on and off on it for months) but I can now present the support for the Motorola Harrier chip-set.

I've been developing on a card with 256MB and a 450MHz MPC7410 and it seems faster than the Rapture. It also can be set-up without the help of VGA memory (so it can be run right after C:SetPatch).

See for more info and benchmarks.

The family becomes bigger and bigger. Below picture shows a carrier in the top left corner. The Rapture card in the bottom left corner. A sonnet on the right and in the middle the new supported card.

Happy hunting!

Developing for WarpOS

Of course it is fun to play with the old stuff on the Sonnet and the Rapture card. But how about new stuff?

The old GCC compiler for WarpOS (2.95.3) was hopelessly outdated and VBCC doesn't support C++ and most of the C sources out there need some adaptation to compile on VBCC.

Enter another project of mine: mos2wos. This stands for MorphOS to WarpOS and is a set of tools to develop for WarpOS on MorphOS machines. Now you can use the newer GCC binutils from MorphOS and what is even better, you can use GCC compilers version 4.4.5, 5.5.0 or 6.4.0 to produce WarpOS executables!

It took a few months to mature, but it is getting to a point that it is getting usable with a freshly compiled SDL library especially made for WarpOS and a very up-to-date C library (newlib 3.0) making porting even more easy!

How useful is it? Here are some examples compiled with version 0.8:

Little brother wants to play too!

Three years ago was the start of the development of the Sonnet PPC PCI card driver for the Amiga. It has been developed for the Mediator for the big box Amigas, the A4000(T) and A3000(T). The first few videos and pictures were showing quite simple programs like Cybermand and Voxelspace. But it was a start. Later Warp3D was made to work and the rest is history.

Over the years it was a big frustration that the little A1200 could not cope with the card. This, as I explained before, because of the bank switching needed in the A1200 mediator. Also, the address range used for the card which is automatically set by the Mediator was giving all kinds of problems

Over the past year, Elbox has been very supportive to get the library working on the A1200. Development on my side has been on and off due to other priorities.

The version of the pci.library went up from 11.0 to 13.5 to get to the point where the A1200 mediator could handle a PPC card.

Before I continue I have to say immediately that it still does not work correctly. But a lot of progress has been made. I guess we are at the same point in time like 3 years ago for A1200 support.

The below video is a PPC 7410 450MHz card with 256 MB of SDRAM running inside an Amiga 1200 with a Mediator TX running Voxelspace.

Simple stuff like this is working flawlessly, but at soon as stress is applied to the system, like with QuakeWOS, bus errors appear. Strangely enough, the crashes appear to be inside the AmigaOS.

Anyway, version 13.5 of the pci.library is still fresh and now we have a basis to further develop on. Stay tuned!

Power in Diversity

A while back, well actually June 2015 or around there, I should a picture of a PMC2PCI card. Since then I have been scouring the Internet for suitable PMC cards. Tried a bunch of them, but none of them worked.

Then I got some help from an expert in PMC cards and he delivered :-)

Below is a Force PowerPMC-250 card with a 450 MHz MPC7410 (G4) card with 256MB SDRAM on-board:

With a PMC to PCI carrier card it was added to my A3000UX and here is the first result after updating the driver:

The card is regarding power consumption on the edge of what the A3000D can handle. The Amiga has to warm up for a couple of minutes before the PPC card becomes stable. It is not the PPC which is crashing, but the 68K when fetching/running code from the PPC memory. But as said, after a while it becomes stable. I guess I need to upgrade my PSU.

I also wish to thank Elbox for their speedy support in updating their pci.library to support these kind of cards!

Hopefully, we can ramp up with faster cards in the near future.

Quake 3 on the Sonnet

Lately, there has been a resurgence of porting of games to WarpOS and Quake 3 is one of them. This port was done by CowCat. Still in alpha, but it definitely has potential.

Sadly, this phone has a worse camera than my previous one. Also, playing with the keyboard which was behind the camera was a tad difficult, hence the weird walking sometimes :-)

Dabbling with Warp3D..

Just a teaser. I've been converting some OS4 and/or 68K Warp3D stuff to OS3 and PPC. Here some first results.

I haden't posted in a :-)

Hope to show you some more the coming weeks. Or not... who knows...

Testing ReWarp on an Amiga X5000

Lately, I've seen multiple posting regarding ReWarp and why the development has stopped. The truth is that it all seems to work fine, except with Warp3D. Also, some sound drivers give problems on the Sam machines, but the main problem is 3D.

I am at the moment not sure if this is because of the backwards compatibility of Warp3D, of that ReWarp is to blame. With Wazp3D everything seems ok, albeit slow.

In the video you will witness two crashes. One in the lowlevel.library (used to be much more 6 months ago, but I guess lowlevel.library has improved in the meanwhile) and one in the wazp3d.library.. The original WarpOS warp3d driver (warp3dppc.library) actually redirects all calls to warp3d.library (in this case a renamed wazp3d.library). Not sure if the crash is due to ReWarp or Wazp3D.

Without further ado, here is the video:

Like stated in the video, any help appreciated. Please redirect your comments to the git issue trackers:
