Yeah, that “shadowing” on an active matrix display is a classic symptom of bad caps. That display should be 100% fine once recapped. Another symptom sometimes is the display looking washed-out until the unit warms up (I have seen this on some old Compaqs before).
Cost would be insane, but if they ever set it up for research like the National Archives, that would be wonderful. Might the Woz be contacted to fund such an endeavor? It would be very sad to see so much technical history molder away in storage un-scanned.
Hit a snag with my SE/30. While loading and patching MacTCP and transferring some other utilities via MacIPpi, the screen started to shimmer and then flipped on black vertical bars! I have Jailhouse Mac unfortunately. This has nothing to do with the Pi software/localtalk setup. I recapped the logic board a couple weeks ago, but have been stricken with sound issues and now this. I only mention it here because I am prepping a new post in another forum seeking advice while I wait for desoldering alloy I ordered to arrive. I plan to remove, clean and reattach the ASC, but I have other problems with the video to diagnose now, so it may be a while before I can really put the Pi through some TCP bridging tests, as it is just too hard to read the dialog boxes for setting IP, gateway, dns, etc.
