If anyone's interested, I've got an archive of all versions of the Turbo040 ROM that I could get my hands on (3.07, 4.01 and 4.11 - the latter two are also in Trag's archive).
I dumped all the ROMs offline and in-system (dumped with copyroms), with the latter containing actual strings in the...
Okay, good news and bad.
Starting with the good: I was able to trace out 4 more pins, you were correct, I needed to trace them from the solder side. Did so in my first try, but must have not pressed hard enough.
That leaves the bad: I cannot, for the whatever reason, find a connection to Pin...
Well - that was fun :) You did pretty much most of the hard work; I have merely put my multimeter to good use and verified most of your connections.
Unfortunately, what you can do in Illustrator, I can't even dream of - so here is my version, about 99% finished (except for 5 pins on the 20L8...
Oh - sorry for plainly ignoring your actual question: Yes, component side would be awesome!
I have some actual 120pin PDS connectors so I'll use them to buzz.
Regarding the PALs: that's pretty much what I thought of doing - i.e. brute-force all input connections (should be 2^10=1024 for the...

If possible (don't have Illustrator at hand), I'd love something that either Sketch can edit (SVG?) or that I can print (read: PDF) and write on.
Regarding "does it fit the SE/30 case": Nope, it does not. Not without the Asante Ethernetcard...
Glad to be of help! I'll try to buzz them asap, for the time being here are the images I shot over the years, maybe you can go ahead and lookup the chips to begin with: https://goo.gl/photos/Bdw1Sa4gCgm9jcF76
As for why this works in my SE/30: I honestly don't know - I acquired the card at...
Okay, so please don't hit me if I'm wrong here - but I have the following card and I'd be able to beep it out.
Would that help your efforts or is this the wrong one (it is working in my SE/30 so I might be completely wrong)?
Hm, reminds me of my journey with this card. Maybe you could have a look at this thread where I've run into what seems the very same problem: https://mac68k.info/forums/thread.jspa?threadID=281 TimHD.
I could partially fix it by using the stock rom and only 8mb of RAM, then it would at least...
