OS4.0 will be using multi-threading emulation for 68k. It's all done, on the fly, so as not to have the 'sandbox' limitation. Provided you are running software that doesn't bang the old chipset or cause GURU code, it should be fine. I'm sure that limitation is alleviated on classic boards, but you also have a slower CPU speed, etc. Nobody knows what programs will run, 'cos OS4 isn't finished yet.  :-D

What are the "sandbox limitations" and what have they to do
with they way the 68k is emulated ?
/me thinks you are confusing a few facts here


Well, every 68k emulation is done on the fly, which means they are independent of each other, unlike UAE. If you read the features list of OS4.0, it states that clearly. Since each trigger of the emulation is independent, there is no need to run the applications within a 'sandbox', since it's hardcoded into the os as a function.

I also stated that most apps *SHOULD* run, provided that they don't bang the hardware or cause GURU code. I went along and said that we didn't know what would run, since nothing has really been tested. With that being said, most of your applications should run, similar to Amithlon I'm sure, but most games will not, since they are notorious for hardware banging.

The only thing that I didn't answer was if OS3.9 was the last of the 'classic' line.  Will it run on 68k? No and they've already stated that, hence the 68k emulation. Apart from that, I don't see anything wrong at all with my 'facts', as you so put it. :-D

I naturally assumed that *EVERYONE* knew that OS4.0 was PPC only. I don't know how many times we've heard SOMEONE say that.
