Atari (Japan) Corporation schematic diagram for the [[Atari 520ST]] and [[Atari 260ST]] main board: drawing C070231, "Schematic Diagram (520ST/260ST)", size D, three sheets. The title block gives next assembly CA070052 and used-on 520ST; sheets were drawn in June and July 1985 and approved in September 1985. The revision block on sheet 1 records revisions K (ECO 00191, 17 January 1986), L (ECO 00217, 27 March 1986) and M (ECO 00225, 22 April 1986). Sheet 1 covers the power input (J9), MFP, ACIAs, MIDI, keyboard connector, RS-232, printer, hard disk and floppy ports and the DMA controller; sheet 2 the 68000, Glue, memory controller, ROM and RAM; sheet 3 the video and RF section.

This is the main board schematic that the scan of Atari's ''520ST/1040ST Computer Field Service Manual'' lacks; see [[Atari 520ST and 1040ST Computer Field Service Manual]].
