This one died, and one of the engineers had identified the bad chip in it by swapping pluggable chips between the two machines. They were going to throw it out, as HP (New Zealand) would not sell them the chip, but required the plotter sent to them to be sent to the USA for repair, cost something like NZ$900. (about US$450) !!! Hence it was rubbish min material, so I said throw it my way. I went investigating the chip with the HP special number on the top, and low and behold, on the bottom it said 6802. Having some other gear with 6802 CPU's in them, I grabbed a chip on the off chance that it was a standard CPU chip, and low and behold the printer now worked :))) Went fishing for a manual for it, and our supplies department sourced one for me for $20. I figured I had a pretty good deal. >Aside from that, those were nice little plotters! They still are :)))) -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you. See http://www.piclist.com/#topics
