It is not going to have the correct scan codes. If it is what I think it is, the "monitor" was actually a terminal. The machine you have probably used a serial connection to the terminal, and the terminal send ASCII code to the computer. If you had the "CRT" part, you could probably hook it to a serial port and use it under Linux. (I have done that with a few "smart" terminals...) The keyboard may generate modified ASCII code, or its own codes that the firmware in the terminal translated. A common method was serial communication with 7 bit ASCII code, and special functions if the 8th bit was set. What you MAY be able to do is convert the keyboard so it will connect to a serial port. But it is probably going to be more trouble then it is worth. Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
