1997 Mouse Trak

This was a MOUSE-TRAK from 1997, REV 2.1, connection cable had been modified for some military requirements.

After reversing the pinout, even with a PS/2 adapter the mouse does nothing, I've replaced the Zilog with a Teensy.

Some parts wears, here are some replacements available:

what old P/N new P/N drop-in
opto sensor ISTS832S OPB822S yes, cut the two mount extremities. E side is the same E as old one, and is where the * on PCB is
click buttons Matsushita AV3402619 ‎AV3402619-A‎ yes
the other click button unknown C&K ‎D6L90-F1-LFS‎ yes
10 8 6 4 2
GND SHIELD NC NC NC DATA
NC NC VCC 5V CLK GND
9 7 5 3 1 (mark: *)

Top view.

Bridge goes to pin 4 of both H and V sensors.

bri dged DATA CLK GND SW2 SW3 SW1 NC
OUT H OUT H OUT V OUT V VCC XTAL XTAL NC SW4

To note:

  • SW1, 2, 3 and 4 are pull-up to VCC through RP1.
  • Both phases of the opto sensors are pull-down to GND through RP2.

Firmware: WIP, https://github.com/rhaamo/mouse-trak-teensy/

Bridge the bridge to GND.

Remove the MCU, pads are fragile, might ends up with trace cutting and some patchs…

Leave the jumper JP1 on the RIGHT: “empty, jumper both pins, C1 empty here” or it will short VCC and GND (don't ask how I know that).

You can leave the XTAL and C3/C4 or remove them, as you wish, the MCU is OTP, just trash it or whatever.

SW1 (left) 21
SW4 (???) 18
