===R/390===

R/390 was the designation used for the expansion card used in an IBM RS/6000 server. The original R/390 featured a 67 or 77 MHz [[POWER2]] processor and 32 to 512 MB of RAM, depending on the configuration. The [[Micro Channel architecture|MCA]] P/390 expansion card can be installed in any [[Micro Channel architecture|MCA]] RS/6000 system, while the [[Peripheral Component Interconnect|PCI]] P/390 card can be installed in a number of early [[Peripheral Component Interconnect|PCI]] RS/6000s; all such configurations are referred to as an R/390. R/390 servers need to run AIX version 4 as the host operating system.
