Hi David!

Great! :)

I think so.

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 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,
