I have a spare PS\2 and also a spare USB cable.
I have seen them but it does not require any programming chip.
I just like making things.
I would like to make a PS\2 to USB adapter myself but the pinouts are a bit strange because PS\2 has clock and data pins. USB has data - and data +.

Please can someone post me a PS\2 to USB adapter pinout because I would want to make one myself.
INOUTS.RU IS THE BEST

Yes, you need a chip: FT232r, or 232Br or something like this. you have totally different communication protocoll, and voltages between rs232 and USB.

Sorry, we talkin' about PS/2. PS/2 has open drained Sclock and  Sdata cables, where the communication is similar like I2C. You can't find any chip, but you have to use a kind of interface decoding logic.

In general such an adapter is not possible.

BUT... you did see a mouse with a PS/2-plug an a PS/2-to-USB adapter (or vice versa).
These devices are not pure PS/2 mice, but they are smart mice, able to detect whether they are connected to a PS/2 or to a USB bus, and will behave like a corresponding device.
Both USB and PS/2 adapters have 2 power lines and 2 data lines fter all.
