IBM 5340 System/34
IBM Says "IBM's General Systems Division announced the System/34 in April 1977 as a low-cost approach to distributive data processing for businesses of all sizes. Centered on the IBM 5340 system unit, the System/34 used as many as eight workstations to provide timely access to current data and offered seven attachments, including the IBM 5251 Display Station. The System/34 was withdrawn from marketing in February 1985."
The system could be configured with up to 128 kB of memory and four disk drives with a total of 128.4 MB of storage.
