That HP has to be the closest the classic Mac OS has come on running on a standards-compliant IBM PC Compatible. No ADB? No auto-detect floppy drive (note eject button in photo)? Makes me wonder how they'd get the Mac OS to work with floppies.

Still, if CHRP had taken off, consumers would have been able to choose between PowerPC and x86 like they currently choose between Intel and AMD. Mighty interesting how that would have turned out.
