   As I wrote in the original followup, in context that was later   
   snipped, "It had a total of 8 bits of storage."   
      
   I think it used vacuum tubes.   
      
   I can't find a reference.  As you can imagine, web searches for   
   "8-bit computer" are not productive.   
      
   There could be any number of reasons why it wouldn't qualify as a   
   programmable computer.  I don't remember, or never knew, the details.
