- What I meant is how much memory can it for exaple move in one 'instruction'.. Does it
- have a own bus for this? (I have heard that the MEGA-ST's blitter can conbtrol 4Mb..

- The C64 has a screenmode there you can put a character on the screen with ONE move (or
- STA) instruction. The video DMA fixes the rest. If you for example do :
-
- LDA #$00
- STA $0400
- STA $0401
- RTS
-
- There will appear two @'s in the upper left corner. (in normal mode) This makes text
- handling very fast. And this mode does not exist on the amiga (I miss it)
