HP 4145A Semiconductor Parameter Analyzer Operation and Service Manual in large 3-ring binder. Has a sticker on it that says "authorized reproduction". Manual Part No.: 04145-90000. This manual applies directly to instruments with serial number prefixed 2149J- and above.
It is in "decent" used condition. The front page is loose from the binder since the holes are torn on it. It has lots of fold out flow diagrams and is pretty thick and heavy.
