OS 4.0 Requirements

[olegil]

Amiga OS is low footprint, but if you're thinking of running large m68k applications emulated you'll need more memory than on a classic machine. Due to the way the emulation works.

Can you even BUY less than 128MB sticks nowadays? (I know SIMMS for CSPPC and BPPC are generally a bit smaller, but remember that on these systems you could dual boot with 3.9 to run old applications without emulation).

It's also expected that you'll be working with higher resolutions in all your programs, and with larger documents. I mean, you can easily play videos on the CPU power in an AmigaOne or a CSPPC, so why wouldn't you? This means you'll need some memory as well.

But a MINIMUM requirement to run OS4 without any JIT emulation should be somewhere around 8MB. On a 320x200 8 bit screen ;-) (most people don't actually know how much memory screens take up. Try to calculate memory for 32 bit graphics in your preferred screensize and you'll see that 32MB won't last for many applications at all... 1600x1200 takes up 7.5MB of memory)

Note that you would probably keep as many screens as possible in GFX memory, though.

But still, a large screen with triple buffering takes up one heck of a lot of memory ;-)

Anyway, even something as simple as a word processor running on a 4 times larger screen will use 4 times as much memory. And DO NOT tell me you're gonna be getting a larger CPU and not run more things.

The only thing I can think of that you might be seeing is that on Windows, if you have a wallpaper, that is stored in explorer.exe's memory space.

And where would the backdrop for Workbench be stored, I ask you?

Seriously: On an Amiga, open up a REALLY FRELLING BIG Workbench and tell me that FAST memory doesn't drop.

Oh, and remember:

The difference between working and non-working is only one typo away :-)
