| 21:53 | Atari ST Book diffhist +1,788 Josh talk contribs (Rewrite from Atari's own STBook Hardware Specification and schematic C104446-001 (both newly hosted - board-level documentation DOES exist). Sound chip is the YM-3439 not the YM2149F; RTC is a Ricoh RP5C15; memory is pseudo-static and not reconfigurable; the panel is about 8 inches from Atari's own 640x400 at 0.27mm, not 10.4 inches (that is the Stacy's); ROM size is internally contradictory in Atari's document and both figures are given) | ||||
