This baby only has 4MB RAM of fast RAM :-( I'm gonna try and track down some Zipps for it, but I have heard they can be quite pricy. The guy I bought it off, said that he had come across a board that fitted over the Zipp sockets that allowed you to use 72-pin SIMMs, but I fear that too would be quite pricy, might have to do a little research. Until then, I am going to enjoy it for what it is :-D
