Recognizeable?? Yes. All things Sony in typical Sony style. Sony has always implemented what they call "the Dragon" mentality in their gaming consoles which basically means take a bunch of devices normally seperated and swallow them up into one package. I foresee this happening with this console. Here is what I know on the drive:
Rohm Motor Driver IC BD7956FS "Rohm 7ch Power Driver for CD-ROM" Datasheet available
Samsung Ram IC K4S641632K-UC75 Samsung 64mbX16 64Mb SDRAM 7.5ns Datasheet Available
Sony RF AMP (optical control) IC CXA2720R <researching test points for laser calibration (this is my field)
Spansion EEPROM IC S99-50111-001 (AKA S29AL016D) Spansion S29AL016DFFI02 16Megabit Flash Datasheet Available <BGA device. Anyone willing to Dump?
Sony MCU IC CXD5063GG-1
IC CXD5064R < not sure what this does yet
Macronix MX25L1005 Serial eeprom 1mbitx1 Serial Flash
JRC/NJM NJM13403 Quad OpAmp <may be used for laser biasing
Rohm BA5888 motor driver IC
Sony KES-400A Optical Pickup Assembly
I haven't dumped the firmware because it is a BGA device. I was really hoping the serial eeprom would be the key to being able to swap the drives.
The MCU has what appears to be a debug bus on the front edge of the board which may be promising.
Its tough to determine the interface on the drive. It is routed to the board through a flat ribbon cable which heads directly next to the SATA Controller on the mainboard but there is more than just a SATA connection through the cable. There is 60 pins total. It appears that they are routing both to the SATA controller and their DVD decoder on the original builds.
