Phenomal manual great resoulution and very legible. Will become very helpfull in future for parts and service.

John Craig - 07/31/2006

Very nice site and the manual is great. A life-saver. Thank you so much!

James Thorp - 12/28/2006

Great original Yamaha manual and no problems at all with the ordering process. Will definitely use this website again and would recommend it to anyone else. James Thorp

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.

Mark Tarkett -

Excellent service, good price, products are excellent. Will do business with this vendor again.
