  5. I recall ... I recall working (yet as a sophomore in EE) on IBM 1620 during 1966-67  at METU Center for Electronic Computing Sciences (literally it’s so called, in Turkish “Elektronik Hesap Bilimleri Merkezi”). There were two disk drives (each of a regular size washing machine) . Each drive had an exchangeable cartridge (disk pack) of 5 MB capacity (and, may be another fixed disk pack inside?). The disk pack was of size about a hard briefcase! CmpE 101 Supplement
