I like Power64 but there is one feature missing that is keeping me from registering. It lacks any communication functions. VICE (the free Commodore emulator, see: http://www.viceteam.org/) has a 'virtual modem' which is patched through to TCP/IP on your computer allowing you to connect to Internet-accessible bulletin boards (see: http://www.orrville.net/telbbs/) and things like the resurrected Quantum Link service (see: http://www.quantum-link.org/). Power64 won't be a fully functional emulator until this fearture is added and then I'll happily register.
