ok what I suspect the museum has is a

Lisa 2/10 - Lisa 2 with an internal 10 MB "Widget" 10 MB hard drive
or a
In 1985, Apple introduced the Macintosh XL - a Lisa 2/10

when we turn it on all we get are all sorts of squares on the screen!

I will now have to keep an eye out for one of the earlier ones.

Just should be happy to have a Lisa in any form I guess... The one we
have is the only one we have had a chance to obtain!

Eric thanks for the history lesson!
