Yeah, that part:

The Lorraine chipset was also very powerful. It took advantage of blitters, chips that allowed information to bypass the CPU completely. Thanks in part to the blitters on the mainboard, the machine was capable of displaying up to 4,096 colors.

Was really confused-sounding. The Amiga only had one blitter, and it was not a discrete chip (part of Agnus I think). The "bypassing" is probably a reference to the DMA that the custom chips used in order to work independently from the CPU.

I grew up/learnt coding on the Amiga, loved it sooo much.

Edit: copypasta fix.
