Try this ebay item: 400529902754 (looked for lsi11) Very nice, but this isn't suprising that much, since this is one of my websites :-) The K1801VM2-1.djvu is the datasheet for the 1801, You should set V=W=B for K180x?[16] on this site, since the German letter W is spronounced like the cyrillic letter B, but russians transliterate this with V :-) The file KM1801VM2-chip-schematics.djvu contains what it sounds that is is containing :-) Regards, Holm -- Technik Service u.
