It's a bit confusing perhaps, but they're talking about display fetch modes, not a burst mode for the Blitter. AGA does have a display fetch 'burst mode', but like said it doesn't have one for the...

OS overhead on low end models (i.e. A500) is around 20-30% CPU and around 100-150KB RAM (much more if you have a HDD or more floppy drives). I measured this several times. It fluctuates and you do...
