Aaron Lawrence - 01/02/2008

Contains mechanism diagrams, parts lists and schematics for all worldwide versions of DC-X88Z. Also includes remote schematic etc. A few non-essential pages are missing such as specifications. Includes the mechanical and electronic calibration instructions for the tape decks.

Dutra Lacerda - 02/17/2008

All schematics for the Euro-PC and some extra info. Needed if you want to replace some missing hardware. A piece of great historical value and for vintage computing entusiasts.

Steve Fink - 07/24/2006

Nice, really nice. I was happy to receive manual in true electronic form, instead of scanned original. This manual includes: Wiring diagram, circuit diagram, block diagram, PC board, adjustment, exploded view, PARTS CATALOG and more.. It's full color manual, not B&W or grayscale :)
