ST built on off-the-shelf hardware

Original Atari ST had 4 custom chips: Shifter, GLU, MMU and DMA leading to specification as 71KHz hi-res display, 10mbit/s ASCI DMA port, MC68000 full speed unlike in Mac Classic... later ATari added custom blitter to ST. https://en.wiki.x.io/wiki/Atari_ST

Beside this four ASIC, ST had WDC1772 floppy controller, Motorola MC68901 and MC6850P, for sound and communication YM2149. Atari ST does not have sophisticated custom chips like Amiga, but it also certainly not built on "off-the-shelf hardware" so I will change wording in article to: "would be built with custom chips and off-the-shelf hardware". --Calimero (talk) 09:45, 6 November 2017 (UTC)Reply
