Mouse Interface card

I got a IIe Mouse Interface Card with a missing dongle.

 

These were soldered to the board with a DIL-10 connector and a 10 conductor ribbon cable with a DB-9 connector for the mouse.

And the ribbon cable was removed (rather forcefully, I think)

 

Anyway, if anyone has a schematic (I know they're hard to come by - I've been looking but Apple didn't relelase schematics willingly for this card) I sure would appreciate it so that I can repair this with a new ribbon cable and DB-9 connector.

Hi Baldrick,This appears to

Hi Baldrick,

This appears to be the schematic you are after:

Indeed, thank you - but there's still some information missing.

I've looked at the mouse port on the IIc technical reference manual and it lists the pinout of the DB9 connector as:

1. Mouse ID

2. +5v

3. Gnd

4. XDir (directional indicator)

5. XMove (X-direction interrupt)

6. N/C

7. Button

8. YDir (directional indicator)

9 YMove (Y-direction interrupt)

 

And the card's J1 connector is:

1. N/C

2. N/C

3. +5V

4. Button

5. Gnd

6. Y1

7. X1

8. Y0

9. X0

 

The remaining question is how do X0 and X1 (and Y0 and Y1) map to XDir and Xmove (and YDir and YMove)

With my meter in continuity

With my meter in continuity setting I get nothing like what you’re showing

Also you’re showing more connections on the DB9 than on the J1

 

On the back of the mouse card J1 has a square solder pad. I usually consider that to be pin 1 and the DB9 pins are numbered

 

Going from there I get

1 to 1

2 to 2

3 to 3

4 to 4

5 to 5

6 to 6

7 to 7

8 to 8

9 to 9

10 NC

 Thanks - I think I can decipher it from your ringing it out with a multimeter.  The 10 pin DIL connector is numbered differently.

I think you've numbered it like this (correct me if I'm wrong):

 ______

|10  5 |

| 9  4 |

| 8  3 |

| 7  2 |

| 6  1 |

--------

 

But they're actually numbered like this:

_______

| 10 9 |

| 8  7 |

| 6  5 |

| 4  3 |

| 2  1 |

--------

 

So your eplanation seems to translate that Y0 = YMove, Y1=YDir and X0=Xmove, X1=Xdir

Becasue in the transposed numbering system, +5V, Button, and GND seem to line up.
