[TenTec] confusion about 563 vs 564

[AC5E at aol.com]

At present I own two of one and one of the other. Being curious I gave them a 
fairly close twice over. The only difference I can find is the decal on the 
front panel. 

So if I were in the market for a fourth VI+ as a user,  I would not worry 
about buying a "real VI+" instead of an "option III upgrade." But if I were 
the sort to collect expensive desk ornaments I might be.
