According to Apple, 4.1 requires a Mac 512K. The 128k could go to System 3.2, Finder 5.3.
I have several versions of Mini vMac, compiled as different machines. When I try to boot 4.1 on a Mac 128Ke version of Mini vMac, it crashes.
Based on this, I would assume 4.1 needs more RAM, and bombs on a 128K (400K disk) or 128Ke (800K disk).
Were there ever any third party upgrades for the Mac 128K that took it to 256K? That would be an interesting machine to play around with.
