Yes, that's what some call nice solution. But I would rather to hear some arguments - for instance why you think that SW accessing HW is bad, and why it "works bad in EmuTOS and works with original TOS" . Just don't get me wrong. I'm for making some new TOS compatible replacement or call it whateve...
Good news: it has been (being) done: https://github.com/e8johan/tosemu ... maybe the old pioneers would remember the oTOSis project for m68k (with all its counter parts like oAESis, oVDIs etc), it seems those guys have come back (hard to say for how long) with the extension of being not only m68k a...
I don't think that EmuTOS is right way - well, unless they change their approach and make it more compatible with existing SW. I think the EmuTOS team has done an excellent job of creating a legal open source clone of TOS. That's the only choice for me if I want something I can legally build on top...
WOW this is amazing!! I wonder why I haven't seen this elsewhere. Would it be able to run Atari compatible apps eventually? Or would it need it's own specifically ARM compiled apps? Save mentioning it on the EmuTOS mailing list, I haven't really announced it widely yet. Right now it doesn't even re...

I've been playing around with the Blitter recently and created a PoC implementation of Conway's Game of Life that uses the Blitter for the actual grunt work. I wrote up a blog post about it and posted the source on my website at: https://www.keli.dk/blitter-life/ Why? Because game of life is apparen...

So as peter says, we can use LDS OR UDS to switch the ROM's chip enable lines low.. but the question is, does that break anything... My question was that I don't think it would matter, as the CPU will only read high or low byte from the bus anyway, so if we put 16bit data on the bus, it shouldn't m...

Some of those cheap HDMI scalers only support composite output. I have one like this: https://www.konigelectronic.com/audio-video/systems-av/hdmi-converter-scart-female-hdmi-output-550581465 These support RGB SCART input and they also have an upscaler. It scales up to full HD. Yes that's the conclu...

Instead of delaying /DTACK by a fixed number of cycles, wouldn't it make more sense to set the delay to be X number of cycles after /AS is asserted? Because the at the original speed the CPU basically ignores the current value of /DTACK until S4 (with /AS asserted in S2).
