| + | This is a very simple | ||
| + | a PIC micro-controller and a MAX232. | ||
| + | |||
| + | === Schematics | ||
| + | |||
| + | Two schematics are presented for two different PIC micros. It should be trivial to port this application to any other PIC micro-controller since they all share similar peripherals. | ||

| + | === Install === | ||
| + | |||
| + | First install [[: | ||
| + | |||
| + | PC Pointer needs some support files from [[: | ||
| + | < | ||
| + | hg clone http:// | ||
| + | cd pickles | ||
| + | make | ||
| + | make install | ||
| + | cd .. | ||
| + | </ | ||
| + | |||
| + | Now we can fetch PC Pointer and and assemble the code. | ||
| + | < | ||
| + | hg clone http:// | ||
| + | cd PCPointer | ||
| + | make | ||
| + | </ | ||
| + | |||
| + | The resultant hex file is used to program the chip. Here I use [[: | ||
| + | < | ||
| + | p14 program pic16f688.hex | ||
| + | </ | ||
| + | |||
| + | === Usage === | ||
| + | |||
| + | Plug an old PS/2 mouse or newer USB mouse with PS/2 support into the input port of the circuit. Connect the serial output into the RS232 input of your old computer. | ||
| + | |||
| + | Boot into DOS and detect the mouse with MOUSE.COM 8.20. | ||
| + | < | ||
| + | MOUSE.COM /C1 | ||
| + | </ | ||
| + | |||
| + | Disable it like this. | ||
| + | < | ||
| + | MOUSE.COM OFF | ||
| + | </ | ||
| + | |||
| + | Windows 95 should auto-detect the device as a generic serial mouse. | ||
