Quick test with Copyback enabled - unsurprisingly it makes an enormous difference!
EmuTOS is assuming Writethrough so I would need to do some work there before I can have it enabled by default, but it's cool to see where it will eventually end up.

Copyback enabled: 221
Copyback disabled: 113

@agranlund Have you enabled superscalar dispatch (ESS bit in the PCR) ?

@agranlund awesome, just curious, is this done at application level, or maybe EmuTOS is doing it at startup already, when detecting 060 for instance?

One of my favourite bit of Atari kit appears to be working, so that's the parallel port tested :)

It works when Atari is client and server runs on the Mac. But it's very unstable if I do the opposite and I'm not sure why yet.

After much faffing about. Finally. FreeMiNT is running!
It's really quite bizarre seeing that same desktop I use on the ST and Vampire, but running on something I've built myself.



Here was the first boot to the default stuff, before I replaced with my N.AES+Thing setup

Bravo!
Is that a 68060 EC you're running in there? Makes sense at this stage of the development. :)
