The Macintosh SE/30 is the most powerfull compact mac. It can take a maximum of 128mb of ram. Sounds really little by today’s standards but compared to the rest of the compact macs it is a huge amount.
Take for example the Macintosh Colour Classic which is the only compact mac with a colour screen. It takes up to 12mb of ram but can only address 10mb.
I managed to pick up one of these machines. It’s not in the best of condition and there are no cables or keyboard with it. I can’t wait to try and test if it’s working tonight.
