>with an Amiga if you had 8x8 text you would need to manipulate eight bytes.
Text rendering was hardware accelerated and very fast.
>Even with the Mac it wasn't this bad because there weren't any custom chips in there and the graphics screen was a very simple 1-bit bitmap setup. You just write to the screen buffer to turn pixels on and off instead of going through layers of register writes with Agnus and Denise.
The Mac is an horrible example, because when the Amiga emulated a Mac, it was faster than the actual Mac. The CPU was of course the same, the advantage manifested on doing the actual drawing.
>you had a complex bitmap screen with a custom chipset that resulted in a lot of latency.
The "complex bitmap screen" (it's called bitplanes) was an optimization which allowed the system to have lightning fast 2d graphics.
>Preemptive multitasking wasn't very workable with a 7.16Mhz CPU and 512k-1MB of memory.
Like contemporary RTOSs, TripOS and AmigaOS did have very workable multitasking. Not just really workable, but actually legendary. Bards still sing songs today about Amiga as the computer that did multitasking right.
>blah blah agnus denise
You throw chip names around to try and sound smart, but otherwise you have no clue about the Amiga.
