Someone said this consists of 3 boxes. I have the box with the blue screen
in it, and the box with the control/keyboard. I don't have the 3rd box
mentioned. My first blush guess is that the monitor box has been dropped, I
think the glass tube is toast. I won't get time to look at it any time soon,
but getting a 21MX cpu board out of it as a spare might not be a bad thing.
Thanks for the advice!
