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
