Technical

The interface can be used with a Genius Bus Mouse.

The following information relates to the smaller Dk'tronics Mouse interface which is designed for the CPC464. The interface casing is designed to fit the case of the cpc464.

Looking at the pictures, the larger mouse interface appears to be made for the CPC6128, but this is not confirmed.

Holding the PCB so that the mouse port is to the top-right, the following, which is not easy to see from the photos, is written on the PCB:

1. Upper left says "DATEL"
2. Lower middle says "CPC464 MOUSE 5/89" (The 5 is not legible, could be a 6)
3. To the right side are 6 connection points. From to bottom these are labelled 0 (or 8 not easy to see), 4, 3, 2, 1, 6.

The following components are inside interface:

1 ST T74LS367AB - 2/4-bit 3-state noninverting buffer/line driver
2 TOSHIBA TC4013BP - Dual D flip-flop with set and reset
1 TOSHIBA TC4047BP - Low-power astable/monostable multivibrator with oscillator output
3 resistors (two on component side, one on solder side)
1 capacitor

The PCB has one 9-pin joystick connector for mouse, and a lead with another 9-pin connector for CPC's joystick port. The interface connects to the back of the CPC. It is claimed this is only necessary for 5V power but this is not confirmed.

It is also claimed that this interface is not compatible with the AMX Mouse, although both report mouse movements as joystick directions.
