>SE(?) could be upgraded to 128mb ram

Probably an SE/30; vastly different internally than the original 68000 SE, more like a MacⅡx wearing a classic Mac shell. Great machine <3 https://en.wikipedia.org/wiki/Macintosh_SE/30

It's a shame so many of them killed themselves with leaking batteries, hard to find even a non-working SE/30 now for a reasonable price.
