 Does anyone recall an Olivetti ST506-interface drive with a colossal

 I'm just curious; I always thought that capacities either equaled or
  surpassed the 5MB of Seagate's ST506 after they introduced it, so I
 was a bit surprised to hear of a drive with < 5MB. 
Hard drives smaller than 5MB were not unusual.  For example, the Rodime
RO-101 was only 3MB.
My list shows Olivetti-branded drives starting at 10MB forever.  So
probably someone else's drive.
