View Full Version : Need help to indentify mouse and connector!

May 13th, 2017, 11:03 AM
Hello. I found this mouse in a pile of cables and I don`t know from what system it came from.
It looks to me they used quality plastic. No marking from the outside. There are marking from inside . I think the writing is in german ( not sure ).

Tried to search: the number of the white paper ( SM CC02 and UM 351 ), number of the board ( L130756/01 ): Nothing.

When searching number of the chip ( E600 38801 DSD431V7Y: ) one Polish website is found:

Is the connector missing some part or maybe the mouse is connected directly to the controller card ?

Can you flip the circuit board over? Need more information to figure it out.

I have seen similar connectors for motherboard mouse and serial ports so my guess is that the mouse has the original connector removed and replaced with the motherboard 5-pin connector. That would save on placing a general purpose port on the computer's case.

See http://www.frontx.com/cpx109_2.html as an example. The picture uses a 10 pin connector but the second 5 pin row is ignored.

Looks too early to be USB mouse.

Thank you for your reply. I am considering to measure the cables and to create custom connector plug to test the mouse.
By the look of the elements and the circuit board I can assume that the mouse is before 90`s, but I might be wrong.
Here is photo of the down side of the board.

I have checked all the listing in e-bay for vintage computer mouse. I have located couple of devices that have similarities to my mouse.

1. First one is this: The similarity is that on the bottom, the lid of the ball is the closed with screw.

2. Second mouse: Here is the same. And the design is somewhat similar.

3. Third mouse: This one is interesting because it has an unusual way to connect to the computer.

Some conclusions that I make. Since I am from Bulgaria , eastern Europe ( Former soviet block country ). Maybe this mouse is from some sort of soviet XT clone.
