Never say die to the old Apple II. A hacker named Vinchysky has melded a Disk ][ controller card with a Xilinx FPGA, which in normal-person-speak means he's enabled you to plug a Bluetooth dongle into an Apple II.
The hookup itself is basically just a USB connection, so you could conceivably transfer in any files you wanted from either a USB drive or a Bluetooth connection to any PC (or any Mac, or any iPhone... or anything with Bluetooth at all... Mind boggled yet?). The writeup of how Vinchysky created it is interesting, while a little on the technical side. Then again, the guy is working technical magic, so we'll let him have his jargon.
And the best part is that we're told this thing will be offered for sale-- he's planning to send them out at a tidy $160, within the next few weeks. If you've got an Apple II sitting around that you're just jonesing to get hooked up to a Bluetooth device, this is what you've been waiting for.
