Thank you very much for the feedback, Colin. That's useful info. I believe they are indeed New Old Stock (NOS) because when I bought some from RS Components 2 years ago and had Kay Koba do a pro-quality socket swap for me, when I got the board back and installed SIMMs, I ended up snapping one end off even without using much force.
And thank you, @djc6 . I've known for a while that CayMac had SIPP in the works, but after watching the video you linked, I came to realize his implementation is better than I had thought. Previously, I knew that SIPP RAM had male pins sticking out, but I was thinking they stuck out the bottom edge of the RAM module, which would mean the pins could be easily bent or you might prick yourself with the pins. But Will's implementation is to mount the pins in the middle of the module, pointing downward, making it less likely you would bend the pins or prick yourself, which is really a great idea.
So once the RAM SIMM sockets are gone from the market, unless MacEffects or someone else steps up to manufacture new sockets with metal tabs (which is probably a costly proposition), the SIPP idea is probably the best solution overall.
And not that it matters too much on an SE/30 motherboard, but it seems that the SIPP modules will sit flush with the board (lower down on the board that SIMMs).
The only real downside to the SIPP idea is that many of use already have a lot of spare SIMMs lying around, and unless you can use those in other vintage Macs, it's kind of a waste to move to SIPP. But many years into the future, that point will likely become moot.
Anyway, thanks again, and do hope this info will be useful to @naruse and everyone else reading this thread. It's been enlightening for me, and I'll probably mention a little about it in the ending segment of the new video I'm working on now, which pertains to adding RAM to the SE/30 by way of YMK's Synchr030/S.
