Allright, here are "the goods!"


ps2_mouse.v. This file contains the ps2 mouse interface.

ps2_keyboard.v. This file contains the ps2 keyboard interface. This file contains an example of the ps2_keyboard module in use. It implements an rs232 ASCII transmitter. You can hook up a PC using hyperterm (115,200 with N,8,1) and see the keys which you type on the keyboard show up at the PC in the terminal window! Also, pressing "-A" at the terminal window causes the scroll lock LED to light up, "-B" causes the Num Lock LED to light up, and so forth. This is tricky to get working, but fun to see in operation. This file shows the ps2_mouse module in use. It uses the mouse to control a small crosshairs on an LCD screen. When the mouse buttons are pressed, the crosshairs change color. The lcd flat-panel which was tested was from an IBM 700C laptop computer, and it required a pixel clock of around 25 MHz (this design used 49.152 MHz divided by two.)
