MARK III/4 Instruction and Maintenance Manual — Digital Edition
Otari's instruction and maintenance manual for the MX-5050 MARK III/4, the half-inch four-track, catalog no. OS3-035. This edition is transcribed from a scan of the printed book and checked page by page against it; the scan's own text layer is poor OCR and was used only as a cross-check. Misprints are kept as printed and factory errors are marked. Figures are cleaned crops of the scan, and the schematic diagrams at the back are shown as scans, each with a full-resolution copy. The addenda bound into this copy stay where they are bound. Its sister book is the BQ-II manual, OS3-031, whose sections follow the same order.
