If your lab dumped one, it was not for obsolescence; its niche successor, the 1130, was still in the future -- and the 1130 was not compatible at all with the 1620, so upgrades were slow and cautious. (Many 1620s were instead eventually upgraded to S/360-30 mainframes, which offered a 1620-compatibility option.) -- John W.
