Would anyone have any of the following HP 64000 logic development system manuals: 64635-90901 64635A State Data Probe Service Manual 64636-90901 64636A State Clock Probe Service Manual 64650-90905 General Purpose Preprocessor Service Manual 64650-90906 General Purpose Preprocessor Operating/Service Manual I have a 64000 and the 64620 state analyzer cards, and I want to build an HP-IB preprocessor interface. The theories of operation and schematics in the above manuals will help me with this. Thanks! -- Dave
