Based on them, ProgSkeet appears to utilize an Actel A3P125 IC (datasheet HERE) which is common among modchips due to its security, and offers enough address lines for at least 2 (if not more) NANDs with 16 general purpose lines and boasts 125,000 system gates with 133 maximum user I/O lines. It also offers JTAG pads, presumably used for programming the device.
Upon completion, ProgSkeet will allow users to downgrade and jailbreak their PS3 similar to the Infectus Mod along with backing up and reflashing the console's memory.
More details will be posted as they become available on the ProgSkeet project, with a video now posted below and a ProgSkeet Review for those interested.

Well, if you are talking about using a calculator to reflash the PS3's flash chips - no. However, there was NORway which can sort of (at least reflash) for you. Of course, its lots of soldering, and it may not even do what you need.
There are actually a TON of uses for a nand chip reader, especially if the clip is good (soldering can get annoying to a nand flash). You name your electronic device, you could possibly get a chance to tinker inside!
does this one be the solderless install for the slim? i'm ready to buy one and i think i'll go with the progskeet if it is solderless and allows dual boot.. can someone let me know if this is the one i need..
