Here is the pin out for anyone keen enough to do a hard wire job
As you can see from the pin out, 68 of the 120 connections are either common ground or not connected. This is from a previous post.
--------------------------------------------------------------------------------
The pin outs for the MV-IC memory card reader are as follows. This will allow a direct hook up from the 68 pin memory card reader socket and the motherboard bypassing the MV-IC (so all that is required is the PCMCIA socket/port).It should be noted that there are no active discrete components on the MV-1C board. I will add some close up piccys later as my image hosting is down at the moment. BTW this has not been hardware tested yet but the continuity has been double checked several times, Im confident its OK but accept no responsibility for any fuck ups.
Looking at the component side of the MV-IC with the reader socket slot facing forward, the 68 pins are laid out as shown below.(in 4 rows)
Rear of socket 2,4,6,8 etc;........34
Third row 1,3,5,7 etc;........33
Second row 36,38,40,42 etc;....68
Front (first row) of socket 35,37,39,41 etc;....67
Now the connections from the 68 pin reader socket to the two 60 pin interconnects, CN 6 and CN 7 from the MV-IC to the same sockets on the motherboard.
CN6 : CN7

There is also a 4 pin audio socket on the board,that connects to the two 3.5mm stereo headphone jacks which are connected in parallel.(standard connection ie tip left, ring right and ground)
This socket is marked MAIN PCB, the pin out is:
1. Left
2. Ground
3. Ground
4. Right
The table doesnt line up very well on the post will link to a more readable version.
