I ordered a C-One board two weeks ago...it shipped from Germany on Monday of last week and arrived here in Sacramento on Thursday. Amazing little computer.
I attached a Commodore 1541 drive to it and started throwing the old game disks at the computer. Amazing when they all booted! For sound you add in a real SID chip (luckily you can get a 64 for parts very cheaply on EBay) on the C-One motherboard.
Toss on a couple of old joysticks and it's the most awesome 64 you've ever seen....amazing since its still very much beta.
You're gonna have a great time!!
