This IBM 1052 was a console output printer for System/360 machines in the 1960s.
It was a cut-down Selectric I/O printer with no backspace and no tab. Keyboard input was provided by a separate keyboard.
The IBM Electronic Composer, announced in 1975, had the ability to store about 5,000 characters in its memory.
Users were able to work on two different documents, thanks to the machine having a main and alternate storage area.
The machine had two power switches, one for the typewriter portion and the second for the memory — which, if powered down, would result in the documents being lost.
The machine was an improvement over IBM's earlier Selectric Composer as the user could have the machine retype stored documents differently justified, rather than having to manually retype them.
One of IBM's early experiments with releasing smaller computer systems was the IBM 5110 Computing System from 1978.
The 5110 was designed to be used for automating common business tasks, such as general ledger and accounts payable. It could also be reprogrammed to provide reports to help management analyse sales, schedule resources, reduce inventory cost and plan future growth.
The 5110 featured a desktop unit that housed a CPU, a keyboard and a 1,024-character display screen. The desktop system unit alone weighed 50 pounds.
It was available with between 16KB and 64KB of memory, and could store as much as 204,000 bytes of information per tape cartridge or 1.2 million bytes on a single diskette.
