Re: The Falcon's confusing history

Re: Geneva

I shot some money over. Thanks for making this happen.

I am looking forward to seeing the source code and seeing what I can do to get it to build with newer compilers and tools.

Re: m68000 reverse engineered

100% cycle exact is of particular use to people doing arcade machine implementations. Many games, demos, etc. used cycle timing tricks to get the maximum out of their hardware. And it's also really just really cool to go back and see how these old CPUs were designed. As for NXP/Freescale (and now Qu...

Re: m68000 reverse engineered

There is a separate thread for Apollo. This thread was supposed to be about the reverse engineered m68000, which is a different topic, and very cool.

Re: m68000 reverse engineered

There is no cycle accurate 68k core. It's a worthwhile goal to emulate it completely. And a great hack. And completely different skills from what Apollo people are doing.

Re: Apollo Team announces developing of Vampire standalone version to run as AMIGA and ATARI ST

FireBee is really great computer and it could be made a lot more compatible with the old software as it is and still faster as it is if somebody would develop for it. But comunity is ignoring it. There is almost no FPGA development at all. MiST is different story. There is a lot of development. But...

Re: Apollo Team announces developing of Vampire standalone version to run as AMIGA and ATARI ST

Well if the Apollo core is truly what they say it is, performance-wise, then they deserve every penny they get and I can understand why they won't release it open source. And it truly would be amazing if they could get an ASIC manufactured, though I really don't know who the market for such a chip w...

Re: Apollo Team announces developing of Vampire standalone version to run as AMIGA and ATARI ST

At the point that you replace both the CPU and the graphics chipset, how much of the original machine is there and worth keeping? They should just go full FPGA, make something built around a large FPGA that can be mounted in a Mini-ITX case and can run either the Apollo core with supporting VHDL cor...

Re: MIST user base

Many of the Zynq devices have a hefty enough ARM core to run a full Linux. So one could use the full USB stack on Linux, not to mention its block devices, etc. to support the core running on the FPGA. Much of the firmware on the MiST right now would be unnecessary. There are Zynq dev boards that shi...

The Zynq series from Xilinx is an SoC combining ARM core and FPGA. Could be used in a similar way.

Re: Most wanted new MIST cores (possible poll)

I suspect Sharp X68000 core would be too much for the FPGA that's in there now. Lots of heavy duty custom chips in the X68000. But I'd love to be proven false.

I vote for SNES.

Re: MIST user base

I love my MiST but a successor machine with HDMI (or at least DVI) output would be nice -- it's hard to find a TV that takes VGA these days. I understand there's licensing issues with HDMI, but it's getting to be necessary. Also the FPGA in there is quite old now. With more gates it should be possib...

Re: Hatari midi compatibility

It might be Aranym that I'm thinking of with /dev/sequencer. But I do recall attempting to use Hatari with my (hardware) MIDI setup and finding it not workable. But this was also about 4 years ago.

Re: Hatari midi compatibility

Last I looked at the MIDI support for Hatari under Linux it wasn't really usable. a) /dev/sequencer isn't really the way MIDI is done under Linux these days and b) if I recall it was write-only, couldn't do read. I doubt it would actually work for running anything with timing, etc. Aranym has simila...

If this case could be fitted with rack ears to fit in a 19" rack, I'd be game, even at that high price.

Re: Homebrew Atari ST ?

That's not true, as EmuTOS can be compiled native ColdFire, and it's a trivial recompilation for most TOS/GEM applications as well. Yes it's not 100% binary compatibility, but for a new machine with different specs one would probably want to recompile with modifications anyways.

Re: Homebrew Atari ST ?

I don't actually personally care about compatibility. That's what emulators are for. For me there's a certain interest/charm in a "new" machine built by the community that continues the 68kish TOS/GEM architecture. It's why I find the Firebee interesting. It has little use as a clone or to...

Re: Homebrew Atari ST ?

If we're talking homebrew TOS/GEM machines, I personally would rather see another ColdFire system after the Firebee, but with the price dropped a bunch somehow, maybe by eliminating the legacy ST/TT ports. And while in there adding a larger newer FPGA. Basically a MiST with larger FPGA, DVI output, ...

Re: Homebrew Atari ST ?

The combination of the 68k and the V99xx series sounds a lot like the Kiwi machine, though that used the 68008 (which is easier to interface on account of lower pin count). That at least shows it is possible for a 'regular person' to design and build such a system, and his plans could be a starting ...

Re: Poll: Did you bought SM124(5) with first Atari?

SM125 came with my (second hand) 520STfm in 1989. I never owned a colour monitor, just hooked up to whatever TV I could get my hands on via modulator. So I never had the same game experience that colour monitor owners had. But that mono monitor was really nice.
