Re: Falcon/CT60e video options

I see you 'forward ported' :) Willy's patch for CT60TOS 1.03c. Apart from that, there's nothing special in that archive - flash060 from CT60TOS 1.03d (Willy's) and drivers.hex from drivers-1.01 package. I don't understand why there is the need for init060.prg? What exactly is that? If CT60e is fine ...

Re: ATARI ST PSU REPLACEMENT ( Power supply unit )

If you look carrefully you can see that all connectors of the new psu are protected by (black) plastic guards on each sides ... it's not possible to touch the keyboard Unless I'm not seeing it properly, it's literally a millimetre from the shield metal. Not to speak about accidental touching the sc...

Why din't you try googling 'FIOZSKBAXXX' instead... you would see it's a perfectly normal SWIFT ID, some of the results are directly from the bank website itself.

Re: Beginning of very long journey

So a Falcon clone for me MUST be able to run Cubase Audio and all DSP based music programs to be interesting. Both CT2 and CT60 needed a patch to run Cubase. :) Of course, it's up to mpattonm to decide, I will support anything which makes the project closer to a successful end, be it a 100% compati...

Joska: I sure know what you mean. But we have some history to build on - AB040, Nemsis, graphics cards, CT2, CT60 etc. So we can see what worked and what didn't. And I absolutely agree with your argument about existing software. So if a couple of DSP-based demos wont work with the new Falcon, it's a...

Re: Beginning of very long journey

Frankly, I'd be interested to know about other cases. Are you sure you are not confusing it with a software bootstrap? I.e. that you use either Dsp_ExecBoot() or NoCrew's bootstrapper to install your code instead of the one by Atari but that is not the same problem. I'm specifically talking about D...

Re: Beginning of very long journey

My impression was that the only reason why people didn't let 32 MHz on VID32 and 50 MHz on its external clock was the difficulty of cutting the VID32 path and replacing it with a separate wire (similarly as done with the SDMA and DSP). IDK, I still feel it would be safer to have an option to run an...

Re: Beginning of very long journey

As Atari users we know that a *lot* of developers knew better than Atari and bypassed the OS. A few weeks ago I was playing around with a DSP modplayer and it uploads it's own DSP bootstrap code. As I person who used to do the same ;) I can tell you it's not that bad. The most known example is NoCr...

Re: Beginning of very long journey

If TOS needs to be changed to work with the 56301, how would compatibility with games and demos be? I wonder that too. But on the other hand, the performance benefit is really high, someone might be tempted to write a new code for it. (I know what you are probably saying now :wink: ) I haven't read...

Of course but that is Videl's job, not SDMA's. They both share the clock for different tasks.

Re: Beginning of very long journey

One thing I do not understand well is, why SDMA is fed not only main CPU clock (16,04..MHz CPUCLKA signal), but also 25,175 MHz from VIDEL and especially, 32MHz from DSP. I mean - CLK8, CLK4, CLK2 and KHZ5000 are derivated from CPUCLKA (correct?), what is the purpose? As far as I know CLK2 (YM2149)...

So you are saying that VIDEL can work on asynchronous clock from the rest of components? I mean would scenario where the Videl is fed from 32,08... crystal, while CPU, FPU, exp.port and namely DMA are fed 40 MHz (/2) from (unsynced) PLL work?

Re: Beginning of very long journey

Switching DSP to 56301 will be a little setback, but hey - its a fun project and thats where the fun is. So back to the schematics. Awesome. Just want to mention it - in this case some minor changes to the TOS are going to be needed. Overclocking the system bus will however not overclock I/O subsys...

Re: Beginning of very long journey

With the CosmosEx in mind, yes, an internal solution would be way better. AFAIK there was very limited use of the external connector -- many tower owners would transform it into the classic flat SCSI cable anyway. Perhaps there are still people having only one external SCSI device (or people willing...

STE vs. Falcon Blitter incompatibility

I have noticed an interesting thing: the Blitter in Falcon doesn't offer an interrupt capability. Normally you can hook up an interrupt vector on MFP's IO3 port which is triggered when Blitter's BUSY = 0 again. And indeed, you can see in the STE schematics, too. Interestingly, in Falcon the same por...
