Ein Mac OS mit Motorola 68060? Nativ? Also nicht im Emulator/auf einem Amiga?

zigzagjoe hat einen Hack gebaut, der es erlaubt, ein Werk-MacOS 7.1 auf einer Quadra 650 mit 68060-CPU zu booten. Hacky, unfertig, kein Produkt, und er will nicht weitermachen, aber es ist ein Riesenschritt, und es ist OpenSource!

Ein 68060/66 dürfte in einer Quadra 650 das ~3fache an CPU-Geschwindigkeit bringen, gegenüber der Werks-CPU 68040/33. Doppelter Takt, mehr Cache, schnellere Befehlsausführung, bessere Sprungvorhersage etc.

Aber es ist noch etwas Arbeit durch Freiwillige zu erledigen, an ROM-Patches.

Macintosh 68060 Redux

Presenting the first time a Macintosh has booted natively on a 68060, to the extent of my knowledge. Source for the ROM modifications and supporting documentation may be found here. This has been floated many a time but I believe this is the first time a 68060 has actually booted Mac OS...

So, as it turns out, the hardware wizard friends in Poland 🇵🇱 were busy. There's a new firmware update for my trusty Warp1260 with some delicious goodies like an MHI driver for hardware MP3 decoding, and an early startup menu with the most important options and information easily available.

Ah, yeah, and 50% more (now: 96K) Level 2 cache available to the '060, which is now 6 way associative, and has lower latency! Yumm, yumm. 😋

And now... Helm, maximum Warp, engage!

Some think about lighting a terrible fire, and then some prefer igniting an entire inferno. 🔥

Otherwise it works fine, finally no annoying issues with this stubby PC keyboard I use for the CD32, and the picture quality is just good, without the need for special adapters and magic. I just need to solve network connectivity on the CD32 somehow (Foreshadowing..? 😉) and it would be perfect.

... in the meantime, if someone could make a good 3D printable cover, that would be nice. Please? 🥺 😅

One notable difference to the TF1260 and the Warp1260 is that the card requires a reboot to change speed, because each frequency seems to have an FPGA core tuned to it. This is a slight disappointment, cards able to switch runtime exist, and can work very well. I never had a single issue with it on the Warp1260. (Although my TF1260 seems to be a bit hit-or-miss.)

On a more important note, I now bumped the card up to 100Mhz. Still runs stable, demos work, etc.

The ACA1260 is installed into the Amiga 1200 that usually sports the TF1260, and ... well, there's nothing to report really. It's running and it's fast. Default settings, nothing is changed yet. All values measured at 90Mhz.

On the minus side - the fan is software controlled and at some RPMs it has an annoying whine. But lets call this part of growing pains, the Warp1260 had a similar issue, which subsequent firmware updates fixed.

@polpo Not sure I ever posted the Amiga 1200 w/ Warp1260 guts on Mastodon, so anyway, here's how it looks.

The fan is temperature/software controlled. I'd buy such a generic cooling solution for almost all my A1200 expansions. Even the 68030 cards tend to run quite hot, especially with FPU & SCSI module, and they're not getting younger either...

Note mine is an early card, so hopefully they improved the powder coating of the heatsink since. 😅

Something about catching Pokemons, and all of them... 😅 I was told full 68060 Rev.6 CPU prices are high, because they are extremely scarce. I don't know, they seem quite abundant to me. 🤪 👍

Meanwhile in Berlin.

Why? Individual Computers is a sponsor of Revision 2025. As part of this, they provided an ACA1260 for the Amiga AGA compo-machine, which just arrived to my place so I can test & configure things before the party.
