You obviously haven't read any of the previous messages on the subject... ;) 
But anyway, I misspoke; I should have said *IBM* PC or XT.
The Olivetti isn't the only one that looked basically identical to an AT&T; I 
recall seeing another one, but I don't remember who the alleged manufacturer 
was.  Unless, of course, Olivetti is the one that I'm thinking of... ;)

Again, you obviously haven't...  ;)  In addition to that, I mentioned that 
one can also detect them by testing for the data bus width.
