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. Judging by your photos and the ones I made last time I had the plotter open, I'm pretty sure that's the same PCA ours has. 07595-18097 U28 07595-18098 U37 Our plotter only had these two sockets populated. The two ROMs contain the even/odd bytes of a 128K image. I combined them and compared them to the dump we took of our broken ROMs (with lots of bit errors), and they seem to be structured very similarly, so this might well be a later version of the same firmware. Unknown U27 - no part number label Unknown U36 - no part number label These are mostly empty and I couldn't find any recognizable strings in there. Might be additional machine code as the U28/U37 ROMs are pretty chock full. The 17225-* ROMs don't look like firmware, but seem to contain several demo plots, maybe for exhibition purposes? Binaries for each chip are attached. All are 27512 EPROMs. Nice, we even have a few of those in our parts collection \o/ I hope I'll find time this weekend to burn and plug them and give them a test run. I have also included photos of the PCA and the EPROMs in position. Hope that helps. Yes, very much, thanks again! All the best Joachim

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

The paper labels on mine have the part numbers: 07595-18095 07595-18096 Could you have read '4' instead of '9' perhaps, or perhaps mine are a different revision? My plotter has two DB25F connectors and one IEEE-488 connector. I'm not sure what other features (besides date of manufacture) might lead to different ROM revisions. > If your version has four EPROMs and the later (otherwise identical) machine > only used two then chances are the four earlier EPROMs were simply combined > into two later ones.

This device is far newer than those parts, but the principle is the same, of course. I should be able to read these out this week and share the contents. -ethan

If your version has four EPROMs and the later (otherwise identical) machine only used two then chances are the four earlier EPROMs were simply combined into two later ones. For example, if the original EPROMs were 2708s then two of those would fit into a single 2716. The 2716 was easier to program as well being only a single voltage device. Combining the images is easy as well. The first 2708 image goes from 000h to 3FFh and the second would go from 400h to 7FFh, as a 2716 holds 000h to 7FFh worth of data vs. 000h to 3FFh for the older 2708. Of course this would also work for 2716s into 2732s, etc. just the data boundaries change to reflect the device size.

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?
