I've recently gotten a bunch of late 1960s to mid 1980s boards, most of which look to be at least vaguely computer related (and broken but that's beside the point lol), and I was curious if anyone knew anything about them. I have some guesses on some, but others I'm completely clueless on. If anyone can help identify them, I'd be grateful! Thanks!

My guesses (or added info):
IMG 287 to 291: Lots of broken early 1970s ICs, I'm guessing it's a simple TTL processor or something, but I could be way off. It's missing a regulator, which I'm assuming was 5 volts.
IMG 292 and 293: I'm 99% certain this is a GE board like 305/306 is, maybe for one of their mainframes? I'm not sure, and I have no guesses as to its purpose.
IMG 294 to 298: Maybe a drive controller or printer controller? I know the ROMs aren't covered, so if I can't find copies of them these will (probably) never work again. I have them somewhere dark as I lack EPROM stickers, and I'm hoping to attempt to preserve the contents.
IMG 299 to 301: I'm almost positive this is a floppy controller, but I couldn't find this exact one googling their name.
IMG 303 to 304: No idea, probably a GE too.
IMG 305 to 306: Definitely a GE board, but I still don't know anything about it.
IMG 307 to 309: Again, no idea. Maybe a controller card of some sort?
IMG 310 top 313: With this one I'm pretty positive it has to do with controlling core memory, considering Telemeter Magnetics was known for that, but I'm not sure what machine it would have gone to.
Thanks again for any help!
