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.

Hi guys, Thank you for the fast and reliable service that your company offers. Great Work :)

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.
