I found this Macintosh SE at a thrift store for $20.00 in "Untested" condition.
I immediatly bought it and took it home to repair it. When I turned it on, it showed an error code on the screen.
Upon taking it apart, I found the ram sitting lose in the bottom so I plugged the ram back in, powered it on,
and it worked! I am still trying to upgrade the HDD to an sd card for more reliability but I haven't got it to work yet.
