I won with my Mac G3 running Yellowdog Linux running MoL (a virtual machine for booting MacOS under Linux but with native processing) running Virtual PC, running a Mac 512k emulator, running a Commodore 64 emulator, running one of those text adventure games.

Well, you’ve still got one layer on me if that text-adventure game counts, but you have provoked the competitive nature of another emulator-geek and therefore [here](http://home.earthlink.net/~ahunter/Upload_Download/Apple2_inSystem6_inSy%236A79D.jpg) is a WallStreet PowerBook running MacOS X running Windows NT Server (in VirtualPC) running Mac System 7 (in Basilisk II) running Mac System 6 (in vMac) running Apple II ProDos (in II-in-a-Mac).

That’s nearly as many layers as you had, and every one of mine is doing a complete CPU emulation (what you’ve got here is a G4 pretending to be a Pentium II pretending to be a 68040 pretending to be a 68000 pretending to be a MOS 6502).

Heh. That’s just as geeky as it is impressive. Well done. 😃
