I remember reading the PowerPC System Software volume of Inside Macintosh[1] at the time, and what I found impressive wasn't that 68k applications ran under emulation on PowerPC, but that much of the Toolbox and System Software were also still implemented in 68k code, implemented in terms of a general mechanism that could also be used by third-party code. This came at a performance cost, of course, but I don't recall the Workgroup Server 6150 I was using at the time feeling significantly slower than my Quadra 605, though to be fair the 605 was at the very bottom end of the 040 Mac line. Then again, with the exception of a larger hard drive and bundled AppleShare software, the WGS 6150 was equivalent to the entry-level Power Mac 6100, as well.
