HP Draftmaster II 7596A: EPROM dumps needed, urgent :-(

Martin, I might be able to help you as I think we have a 7596A.

Are these EPROMs from the processor PCA?  Are you able to tell me which 'U'
numbers they are in the PC board? 

I haven't looked at the plotter itself, but the service manual we have shows
the following part numbers for the processor PCA 


So I'm not sure if my manual is old and the plotters at that time had 4
EPROMs and yours is newer and has 2? Or are they on another PCA somewhere?

Let me know. 

If the plotter we have is in the main museum facility I can possibly help
you, I will check.

the EPROMs are labeled 07595-18045 and 07595-18046.

Can anyone do a dump for me? It's really urgent. Our local hackerspace wants
to get rid of it, if there is no chance to get the Firmware again.
