In the same package as the one for socket 5/7 boards, here's the rest :

Weird AST mobo (there's 2 of them)

One of the 3 CPU expansion board for the ast mobos. There's a 386sx16 one, a 386sx20 one and a 486dx25 one. Unfortunately they use weird ram kind that I've never seen. I've put 30 pin and 72 modules for you to compare

And finally, a 286 mobo in rather good shape ! It's battery leaked, but that should be fixable, the damaged area isn't that big and that's just a 286 so there shouldn't be any inner traces. One thing that bothers me is that one of the rom chip had a missing sticker. I hope it wasn't erased over time as this would be a pain in the ass to reprogram for me.
I didn't show an mfm controller and a floppy controller with a rom chip. That might be useful for my 8088 if I manage to fix it somehow
That's it for today. I'm quite happy with all of these !
