I think you're right. I don't think I'll ever come across a 68881/68882 math coprocessor in the wild, and even if I do I'd have little use for it. Majority of the software I use probably wouldn't take advantage of it and run just fine on the 68030 itself.That looks really nice!
I think that smaller socket just above the '030 is for an FPU. Most software doesn't use it (I think some spreadsheet software and scientific/mathematical programs use the FPU extensively if one is available), but if you come across one (for the '030, I think either a 68881 or 68882 would work if you can find one in the proper form factor), it might be a neat thing to install "because you can"

Regarding serial cables, doesn't one need a special crossover cable for direct machine-to-machine LocalTalk?
I thought you could directly connect two machines together and have them talk to each other, but I guess not?
I knew you needed a special dongle to be able to use AppleTalk/LocalTalk for larger networks
(Are there any other ways to remove the battery if you don't have a soldering iron?)
When I had an accelerated SE I had to bend the frame and take the motherboard out essentially straight down. The instructions specifically said to do so as there wasn't enough clearance to slide the motherboard back in with the accelerator attached. If you got it in one of the frame rails and pulled the other out to pop the motherboard in everything would *just* fit. It's very annoying to have to do so, but since Killy clips haven't been made in ages and whatever's left isn't going to be super strong (not that they ever were in the first place) it's the best option available.Unfortunately, getting the logic board reinstalled in the machine was hell. While the logic board on my other SE slides right back in both rails, for some reason (perhaps the accelerator card?) this logic board doesn't want to. It only wants to slide back into one of the side rails, but won't easily go into the other - as if the space between the two rails is too narrow. I actually had to (as carefully as possible) force the board back into the slotted rails and shove it down.
The battery is still coming out, at least on this SE. I'm thinking about buying a new PRAM battery holder for the SuperSE so I can install a new PRAM battery that can be easily swapped out. While I don't really care about having to reset the time/date settings on my stock SE and Classic, there may be some settings on the SuperSE that may need to be retained for proper operation. (The 1988 Varta battery still holds time perfectly on my stock SE. So far it hasn't even drifted off by a minute. Regardless, I'd like to remove it. I may also install an aftermarket PRAM battery holder on that board when I get it recapped.)I think that is so neat that you found that accelerator. To date, with the exception of an external projector card in a Plus and an ethernet card in an SE/30, I have never come across a Mac with anything exciting. In fact, pretty much everyone that I find only has its base RAM. I am excited to see what you will do with this.
It's a pain. I was worried about possibly damaging the logic board, but the only way I could get it to go in was by pulling the rail out and forcing the logic board in. It finally went in... and then I realized I forgot to reconnect the monitor port cable. Oh well, that port will likely never get used anyways.When I had an accelerated SE I had to bend the frame and take the motherboard out essentially straight down.

It looks to me like all of the capacitors on your accelerator are tantalum capacitors. They are probably still fine, as there is no fluid inside them. From what I have heard though, when tantalum capacitors do fail, it is usually spectacularly (in a puff of smoke). Maybe replacing them preemptively is a good idea, but I don't think that this is something that people ordinarily ever do.Does anyone know if the Mobius 030 accelerator card should be recapped as well?
I think you should just buy a multi-pack of various sizes of ESD bags online. That way, you'll have every kind of size possible, not to mention it isn't much cheaper to buy a single bag vs 40. I have fit Mac SE boards into the largest size included here: https://www.amazon.com/Resealable-Antistatic-Anti-Static-Motherboard-Electronic/dp/B07M95GLVR/ref=sr_1_9?dchild=1&keywords=esd+bags&qid=1611943213&sr=8-9With that, what size of anti-static ESD bag will I need for the logic board?
I don't think I'll recap the accelerator card. I've heard of the RIFA caps blowing and putting out lots of putrid smoke, but I don't think I've heard of other tantalums going bad unless "provoked" (over-voltage, etc.)It looks to me like all of the capacitors on your accelerator are tantalum capacitors.
