ICT 1300
The ICT 1300 was identical to the 1301 in every way except that its card reader was limited to 300 cards per minute and its line printer was limited to 300 lines per minute. It tended to be sold with less core storage and drum storage and without magnetic tape. A drum with only a quarter of the read/write heads fitted was commonly used giving just 3,000 words of 48 bits as backing storage.
