Summary
SEGASATURN CIRCUIT SCHEMATIC Rev.10 — subject SEGASATURN MAIN VA0.5 + CDSUBSYSTEM, three A-size sheets. Both titles are the document's own, recorded in the PDF metadata.
Japanese annotations throughout (for example 「IC24周辺回路」, "circuitry around IC24"), so a Sega Japan drawing rather than a regional edition. Main memory is shown as HM5241605TT17S SDRAM at IC3 and IC4 on +3.3 V.
The only VA0.5 source on this wiki, and the clearest confirmation here of Sega's post-Model-1 convention: CE1–CE53, nearly consecutive, for electrolytics, with a separate plain C run for ceramics.
No parts list — values appear only where a drawing carries them — and no board layout, so a designator found here cannot be located on a real board from this document alone.
The PDF carries a text layer, which is unusual for a schematic here and makes net names and device numbers searchable.
Described on Sega Saturn VA0.5 Schematics.
File size: 512,865 bytes.
