How much is a partial Lisa worth?

I have the chance to pick up a Lisa CPU unit only. It has a 3.5" drive visible from the front, no cards visible from the outside (couldn't open the back to look in), and does not come with keyboard or mouse. On the back are a video out jack, two 25-pin serial connections, a reset button and an interrupt button. The power switch lights up and is next to the 1/4" keyboard jack. When I turn it on, the screen looks good and I can see it going through its paces. It complains that there is no keyboard. I have no idea how much one would cost, but I expect it's >$50. I do not know how to tell if has been "upgraded" to a Mac/XL or if it is original. What's a good price for most of a Lisa? -ethan ===== Visit "The Seventh Continent" http://penguincentral.com/penguincentral.html __________________________________________________ Do You Yahoo!?
