Another update on my progress. I've still got some case cleaning to do on the 6100s, but I've gone down a detour as I really want these to be usable for their future owners and I did not get any HDI-45 adapters for getting video out to a modern monitor. This has lead me to try my hand at PCB design to build something that will plug into the HDI-45 port and output either the Mac's DA-15 connector (for purists or those who have a Mac monitor they want to use with it, or those who want it to work with the DOS Compatible card's Y cable), or a HD-15 VGA connector for hooking up to a modern monitor. Making good progress - I've got a PCB that replicates the HDI-45 male connector's pins. And have PCB designs that I think will work and provide adequate clearance on the 6100. The VGA adapter will also work on the 7100. Not sure on the 8100, but it may be possible with longer pins in the HDI-45 connection.
I did get around to testing out the monitors. A surprising number of them powered on and at least somewhat worked. I forgot, but there was actually one Apple AudioVision 14, which uses the short lived HDI-45 connector. It was in ROUGH shape, and the connector was pretty rusty, but I tested it out and it was working pretty well. Needs some geometry adjustments and pincushioning, but it does work:
Side note, when you have strewn CRTs all over your workshop floor, and you're moving them around, be careful where you place your hand if you fall over... Could have been much worse, but the top of this AppleVision 1710 is no more. Fortunately the case was already partially broken (cracked on the trip in the haul) and the monitor was one of the ones that showed no signs of of life (it was on the floor and the previous owner said they had had a flood - you could see the water level on some of the monitors). Still, not what I was wanting to do, but fortunately I didn't get cut on any of the sharp plastics (I did stab myself under the fingernail with a shard of plastic while trying to remove the broken base of a Dell Trinitron monitor). Stay safe out there!
Three of the four Macintosh 16 inch displays work. One is very dim, but functional. Hoping I can clean one up and use it with the Quadra 650. And find a good home for the other two. Unfortunately, The monitor I was really hoping to get working would power on, but shows no video or other signs of life is the SuperMac SuperMatch17. The two PC monitors with trinitrons I kept both work and have fantastic pictures. I probably won't keep them, but after seeing them, I might reconsider. The Dell had a shattered base that I ended up giving myself a nice deep stab under my fingernail trying to get it off. Probably should have been wearing gloves given the sharp plastics and filth...
Finally, I decided to inspect and test some of the Centris / Quadra 610s. I think they must have either been stored lower and succumbed to the flood, or they are just more sensitive to the humidity they were stored in. Where I believe I had around 10 of the 13 6100s functional, I would guess only 3 of the 610s seem like they will be able to get working. Several were battery bombed and it took out half the board, or rust, or the one I pictured in my original post that had a layer of mud covering the board. I opened up one and there was a vine that had made its way inside and had set up shop in the case.
I was hoping to salvage more, but we'll see when I dig in more to test power supplies and other components. One had a tray loaded internal CD-ROM I'm hoping will be salvageable. Hopefully I can wrap up my work on the 6100s, get video out solutions for them, and then move on to the Centris / Quadra 6x0.
