===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 MHz or 77 MHz [[POWER]] 2 processor and 32MB to 512MB 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 nuber of early [[Peripheral Component Interconnect}|PCI]] RS/6000s; all such configurations are referred to as an R/390. R/390 servers require AIX version 4 to be run as the host operating system.
