see also IBM 704 Vacuum Tube Assembly (1957) on second floor [CMHC].

To make the IBM 604 useful for technical calculations, the machine was combined with a 402 or 417 electronic accounting machine for printing and one to three type 941 auxiliary memory units; this combination was successfully sold as the Card-Programmed Electronic Calculator (CPC). Stanford University operated an IBM CPC in the 1950ties -- see the picture of Professor Herriot with one of the programming plug panels on the first floor.
