Hi David! David Collins: > Martin, I might be able to help you as I think we have a 7596A.
Great! :) > Are these EPROMs from the processor PCA? I think so. > Are you able to tell me which 'U' > numbers they are in the PC board? No, not now. The plotter is in the shackspace in Stuttgart and I was not there for several weeks and now I found an email saying they want to get rid of it. I already asked for the dumps here one year ago and now it seems to be really urgent. > I haven't looked at the plotter itself, but the service manual we have shows > the following part numbers for the processor PCA > > 07595-18039 > 07595-18040 > 07595-18041 > 07595-18042 I know. As I was told by the guy who took a look inside one year ago, these parts do not exist in the revision we own. But I think, they only put the firmware in two EPROMs at HP in a newer revision of the board. And if not "only", I think the dumps would be helpful anyway. It would be great if you could do a dump for me :-) Many thanks, Martin -- Martin Peters mar...@shackspace.de
