I've got one and even bought a bloody big case for it, but it always got pushed aside for other Amiga projects like my A4000 tower-up, my Minimig or C-One.
Bang for buck, it is a great machine to at least try MorphOS and decide whether to upgrade to a bigger, more powerful motherboard & CPU. The RAM is definately a problem.
I have to ask, my Miniming v1.1 got a RAM upgrade by soldering RAM chips onto the existing chips and then a big more buggering around with some wires. Is "anything" similar possible with the Efika?
How about the Amiga trick of nicking RAM from a graphics card and allocating that as extra "SLOW" RAM? OK, performance might take a hit when it is used, but anything that increases the rather sad 128MB might prove useful.
