Latest aquisition: HP 7596A plotter

The 3274 was gone from the Uni surplus this morning, but the HP 7596A plotter was still there (going on two months). I asked what they could do on the $100 price... $50 was their initial offer, then $25 after the manager saw me fiddling with it to make it do *something* (some yutz misloaded the pens and it was unhappy). So now I have an E-sized pen plotter. It has serial and HPIB interfaces and I'm looking for a quick-start reference guide. I've been googling all morning and haven't found anything overtly helpful. I know that I can get paper and pens from Western Numeric Controls, but manuals are scarce as hen's teeth. One quick question... how to I get a demo plot? I see the menu on the internal LCD, but no combination of buttons seems to initiate a plot. Reset is another option and it asks me to confirm, but, again, I can't figure out what to press to confirm. There's buttons around the LCD for menu navigation, a "dot" button, eight pen buttons and some cursor-style direction buttons. Thanks for any tips from a novice to large-format plotters (all my experience has been with A/B-sized HP pen plotters). -ethan __________________________________________________ Do you Yahoo!? Yahoo!
