[a] DRAM dominates for desktop system memory. SRAM is used for CPU cache. SRAM is also found in small embedded systems requiring little memory.
IBM 5203 printer for System/3. A smaller (IBM 5203) printer was attached to the main system. The 5203 was a chain printer with interchangeable cartridges. It could run at 100 or 200 lines per minute, based on model. [9] Later on, IBM offered multiple models of the existing IBM 1403 printer line, which had been originally built for the IBM 1401 ...
