This is it! This is "The Red Book" the 1978 Apple II Reference Manual. Gives you all the schematics, the peeks and pokes, every thing you need to know about the Apple II. This is the "holy grail." ... well, this and Gaylor's Circuit Description.
But, this one is in very good condition. No markings; binding is tight; a little wear on the outside top binding, but otherwise a collector's special delight.
Will be shipped in a USPS Priority Mail box.
"The pride of any Apple II geek's library!"
Please give it a good home.
