I bought Office 4.21 for Mac (Word 6.01, Excel 5, PowerPoint 4 I think) on eBay a number of years ago. It works great IMO.

I am familiar with many of the last versions of 68k-compatible software if anyone has any questions.

The next versions of Office for Mac (Office 98, 2001) can run on some ports of the SheepShaver Mac PPC emulator (runs up to Mac OS 9.04). I kept getting a error during the make phase which I haven't been able to fix.

I did get the G3\G4 Mac OS X emulator called PearPC built and it runs on Maemo, but I gave up after 20 minutes or so waiting for it to boot Mac OS X Leopard. The emulator can be pretty slow on Windows\Linux system as it is.
