Both depend on a single, central, memory controller that can only handle 2 banks. So if you buy with 1MB, it's a hack to upgrade it to 4MB, and once at 4MB, it's non-expandible. Also, I don't believe DMA from plug-in cards is possible (at least not that I can see). HOWEVER, as several people have pointed out via email and posting, the latest Acorn machines are much more sophisticated. I have the same problem the poster from Canada has: no information! -- Dan Babcock > Regards, Kers.
