Could we get some small NAND flash chips on the menu? Maybe you could find some caches of old, discontinued 4M-32M chips and sell 'em to us hobbyists? Looking at Mouser & DigiKey, they only have one or two types in stock, they’re bigger than I need. (If I really needed a lot of flash, I’d add an SD socket or USB key.)
xD cards are nothing more than a NAND flash chip in a removable package:

you can solder directly to the contacts or you can get a cheap xD card read for a socket.
Yes, and that's a reasonable way to go for prototyping & hacking, but I'd like to be able to make a clean version when I'm done (rather than have an XD card glued onto my board, with a dozen little wires soldered to it). (I'm actually fiddling with Mattel JuiceBoxes, and I'd like to end up with a board that's like the MP3 cartridge, but with a NAND flash to permit execution of files on an SD card in a removable socket. Basically, a clean version of the [[MP3 hack](http://www.elinux.org/wiki/JuiceBoxUMDCart) on the [[JuiceBox Wiki](http://www.elinux.org/wiki/JuiceBox).)](http://www.elinux.org/wiki/JuiceBox)](http://www.elinux.org/wiki/JuiceBoxUMDCart)prpplague:

Hey Kam,
Please let us know how these work our. I’ve seen them, and thought about trying some.
thanx,
Robert
