I have 2 865 models and a 855.
They both have the same pcd and on the 865 models a board bridges where the tda1541/saa7220 go with a saa7310 bitstream..
Once this board is removed,(be carefull as I had to repair some tracks)
You can fit the proper chips and to complete ,you just need to add a crystal from the board you remove and 1 cap and a few resisters.
C301=100uf 25v (take the blackgate of old board)
R303/301=4.7 ohm
R202=1ohm
R304=10ohm
R410/417/409/418=33ohm
R419/420 100ohm
R415/416=22k ohm
And thats it.
I am still waiting for 33ohm so I can test it.
I have also done a no oversampling mod to all 3.
Cant wait to try'em out
