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.
