This is an 8-pen 8.5"x11" autofeed plotter with Serial and HP-IB interfaces. It's in good shape, and seems to be almost working, but something's gone awry with the autofeed mechanism -- it's not picking up paper from the tray. Some of the pens still have wet ink in them :). A friend of mine was tossing this out and I couldn't let that happen, but since I already *have* a working 7550A I probably don't need another. Anyone interested? This is in Seattle, drop me a line... - Josh
