One of my CCs runs 7.6.1 quite comfortably on its (max.) 10MB of RAM (and max. VRAM). Almost sprightly, even, but far from blistering. I have to sympathize, however, with the notion of a lesser System, but no less RAM/VRAM. Macgeek417 has suggested the ideal solution: a custom construction of System 7.1.3, based on 7.1 Pro (7.1.1), with judiciously selected nuggets retrofilched from 7.5+. Finder 7.1.3 is the key to triumph. Don't be downcast if Finder 7.1.3 isn't in the Thread Manager folder as the pickle was seeing it, but it is present in the Drag & Drop folder.
