RE: anyone use the IBM 1620 computer?
According to a book I have handy about IBM's early (pre-360) computers it initially had 20,000 digits of core and it was later increased to 60,000 digits. Each digit occupied 6 bits. It would seem likely that the disks would have been the IBM 1311 which was their first disk product with removable packs. the 1316 disk pack used in that drive had six 14" platters with a total capacity of 2 million characters. Disk storage was only available on a faster version of the 1620 introduced in 1962.
