I've inherited an antique computer with 64MB of RAM. I'd like to install emacs, but only if it will run. The emacs manual doesn't seem to have any system requirements listed. In fact, general searching only turned up the original's then extravagant 1MB RAM requirement and the joke that emacs stands for '80MB and constantly swapping.'
While larger RAM is on the way - 128MB - it would be nice to know whether to wait or not without having the system shudder to a halt.
