interesting post
am also wondering if there is any program out there that can turn these into scrypt hashers. Is it really something with the components that make them unable to mine scrypt?
Ya, and Nay.
The algorithm is hard coded into the ASIC, and in there is SHA, used for BTC and other SHA based cryptocoins.
LTC and other SCrypt-based coins use another algorithm that is not (yet) available as ASIC, so you're stuck to GPUs.
Thats why mining on GPUs gives a few hundred MHash/s on BTC but only a few kHash/s if SCrypt: The Algorithm is different and not very optimized to be done on Hardware.
SHA is.
