I realised the attachments wouldn't show in the general email but I figured the only
people who needed the binaries right now were the original posters who got them directly
from the email.
I'll put up the binaries of my EPROMs and the ones of yours when you post them as
downloads in the museum website over the next few days so they are there for the future
for anyone else who might need them.
Martin/Joachim, let us know if any of the files you now have or will get fixes your issue
and if a Draftmaster II is saved as a result!!

Here are the binaries for all the EPROMs on
processor PCA for my 7596A. The
PCA part number is 07595-60100 and is different from the one in the manual
which is a 07595-60200 so I assume my PCA is older than the one in the
manual.
I did not have an 8mm socket wrench with me when I visited my 7596A so
I wasn't able to entirely remove the cover. I did slip the camera in
under the lower edge and did extract U28 and U37 from mine for
dumping...
The EPROMs on the PCA are as follows:
17225-18001 U26
17225-18002 U35
17225-18003 U41
17225-18004 U42
These were empty on my plotter, best I could tell.
07595-18097 U28
07595-18098 U37
I found these in those sockets:
07595-18095 U28
07595-18096 U37
Unknown U27 - no part number label
Unknown U36 - no part number label
These sockets are definitely empty on my plotter.
Binaries for each chip are attached. All are
27512 EPROMs.
This list doesn't support attachments, so most of us didn't get them.
I'm happy to send along my copies of 07595-18095 / 07595-18096 when I
get them read out.
