The whole drive assembly is connected to the motherboard using 3 flat flex cables: One is an IDE connection to the dedicated drive board of the PSX-part, one provides power (5V, 12V, GND) and also connects the PS2-part sled motor to the motherboard (since it is controlled by the motherboard directly), and one connects the KHS-400C PS2-part pickup to the motherboard, since it is also directly controlled by the motherboard. The spindle motor is always controlled by the dedicated PSX-part drive electronics over IDE, even in PS2 mode. | ||

== Optical pickup == | |||
=== Notes === | |||
* KHS-400R seems to be a rebadged Sanyo SF-HD7 with a different plastic cap to remove the "HD7" labelling present on the SF-HD7; they are completely drop-in interchangeable | |||
* KHS-400B and KHS-400C are electrically compatible, but differ in thickness of their bases, making them mechanically incompatible (putting a KHS-400C in place of a KHS-400B will seem to work at first, but the flex cable will bend heavily once the pickup reaches the outer area while moving) | |||
* KHS-400C and KHS-400R / SF-HD7 are mechanically fully compatible, but require different calibration data for [[MechaCon]] | |||
* There are 2 different lens assemblies for KHS-400B, which require different calibration data for MechaCon: T487 (white ring around lens) and T609K (yellow ring around lens). T609K seemingly was introduced with the D/D'-chassis. Some early T609K have a white ring around the lens. These pickups have a violet marking at the adjustment screw. (Markings in other colors don't indicate any lens assembly variant, only violet does) | |||
* KHS-400B (with T487 lens assembly) can fully drop-in replace KHS-400A, but not vice versa (mechanical reasons: KHS-400A in a drive meant for KHS-400B can't press the home-position switch near the spindle). KHS-400B with T609K lens assembly can also be used, but requires different calibration data for MechaCon. | |||
* PSX consoles always have 2 pickups: One KHS-400C (for PS2 games only) and KWS-200A (XPD-001 motherboard) or SF-DB11 (XPD-005 motherboard). Every disc will first be detected by the KWS-200A / SF-DB11, so if this pickup is broken, the console also won't read PS2 games, since the KHS-400C only becomes active once a PS2 game has been detected | |||
* The drive mechanisms of earlier and later PSX consoles are completely different from each other (except the KHS-400C), so you can't replace a KWS-200A with a SF-DB11 or vice versa | |||
* PVR-802W and KHM-430 seem to be mostly identical; KHM-430 is probably a rebadged PVR-802W, as it is with KHS-400R / SF-HD7 | |||
