Sony DTL-H2700 Dev board (ISA bus) (CPU, ANALYZER ...?)

Another revision of the DTL-H2000/DTL-H2500 boards. Consists of a single ISA card stacked together with two huge daughterboards, and probably additionally having a small connector daughterboard. Exact chipset is unknown (there might be components on both sides of the PCBs, most of them not visible due to the PCB stacking, so taking photos/scans of the PCBs would require advanced techniques with screwdrivers).
Currently the only known chip name is an EPROM (MX 27C1000DC-90, with sticker "Title=DTL-H2700, Ver=1.00, Date=96.12.4, Sum=046B No."). The ISA card is having markings: "SONY HCD MWB-7? MADE IN JAPAN, PA47 1-589-003-01 1642E03A0".
One uncommon feature is an extra connector for a "trigger switch" (foot pedal), which is reportedly used for activating performance analyzer logging.

  Jx    98pin ISA Bus Cart-edge (2x31 basic pins, plus 2x18 extended pins)
  J5    68pin Connector on rear side (unknown purpose)

Unknown what COH-2000 was used for. One theory was that it's related to PSX-based arcade cabinets. The 68pin connector might be also related to the 68pin PSX "Parallel I/O" expansion port.

Sony DTL-H2010 (Black External CDROM Drive for DTL-H2000, CD-R compatible)

External front loading CDROM drive with Eject button. Connects to the blue 40pin connector on DTL-H2000 boards.

The required cable consists of a Yamaichi NFS-40a female connector (blue connector on DTL-H2000 side), 0.635mm pitch ribbon cable, and 3M Sub-D MDR40 connector (silver connector on DTL-H2010 side). But caution: the odd/even pins on the cable are somewhat swapped, on DTL-H2000 side the wires should be ordered 1,2,3,4,..,39,40, but on DTL-H2010 side they should be ordered 2,1,4,3,..,40,39.

Sony DTL-H2510 (Gray Internal CDROM Drive)

This is some sort of a mimmicked front loading PC CDROM drive (consisting of a tray that contains a normal (top-loading) PSX cdrom drive unit).

  ICxx   ?pin Unknown if there are further ICs (eg. CXA1782BR should exist?)
  CN1   10pin Connector to daughterboard (with drive unit)
  CN2    4pin Connector to PC power supply (12V/5V and 2xGND)
  CN3   50pin Connector to DTL-H2500 or so? (need "PCS-E50FC" plug?)

There is no eject button, unknown if there's some eject motor, or if one needs to push/pull the drive tray manually.

Sony SCPH-9903 (Gray SCEx-free Playstation)
