I just came into possession of a PS3000 which had had the drive and all cables associated with the drive removed. This thread, especially 4MBupgrade's photo's really helped out. I figured Iwould share the pinout I pulled together and used to get a Gotek installed working. Not a lot of documentation around and I figure if this helps anyone then great. Really interesting also that there are pads for a FDD2 as well. My guess is that at one point there were plans for a two drive version...there's plenty of room for it in the casing.
