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.

Just got this Manual downloaded... Scan is PERFECT! This is EXACTLY what I needed. However, please update your site info to state that it may take more than \"a few hours\" to have the download available after payment - - - I had to wait 4 days, in my case. Otherwise, I am very happy with this!!! Thanks! --- User-Manuals.COM comment We\'re sorry for delay, we had major problem with our download server, but all is ok now and downloads works as previous.
