Apple IIgs RGB Monitor schematics are available in US Letter sized sheets, sorry, it’s all I have. Some time ago these were input in Autocad and printed to tabloid sheets. The electronic versions have long disappeared. The first of three sheets is a single US Letter page and the second two are presented as two US letter sheets to make up one tabloid sheet. The PDFs are readable on screen and print well. http://apple2.info/downloads.
