Servo PCB for L1210/65 (CDM12.1/VAM1202) from Daisy -where in use by Marantz (Schema)

I need a schematic for the Servo/Decoder PCB, which is in use in the loader L1210/65 from Daisylaser (for mechanism CDM12.1, VAM1201 and VAM1202) - go to
pictures
Daisy call this PCB as follow:
"New CD7 II (SAA7327) servo-decoder for improved playability and reliability"

I read follow numberings on the PCB from Daisy (have a look to the PDF images):
1) HECD-019A
2) DN24A533

are to find the predecessor of this servo boards at a CD722 from Philips (scroll down).

There was produced several top class cd player in very small amount, where this PCB is in use. AVI (lab Series), RESTEK (Mini Pla), Northstar and various models from Micromega are examples.
Here some links of such brands:

Unfortunately this PCB isn't in use in Philips/Marantz CD Players like CD710, CD722, CD63 or CD67. Thus the service manuals are not helpful.

Who knows brands, which have produced cd player in large amount where this servo board is inside (like Marantz) ??

Such brands must actually publish the schematics (in opposite to DaisyLaser).

Thank you very much for advices

Unfortunately no success until now.
The actually question is an other:
In which Philips/Marantz models (both CD Players , burners, ghetto blasters and Hifi systems) the same boards are in use?
If I know this, it is easy to get schematics and service manuals.
Maybe Cyrus and AVI know this - try to call and ask this question. My english is too bad for a call by phone.
 
Hello everyone.

I am going to copy the servo board.
can i kindly know what this P87C58 chip is for, it would look like an eprom.
