 RM-200 is based on the A20R Pyramid architecture and very similar to the early [[RM 400|RM-400]] (without C or E suffix).

 [[Image:Rm200c internals.jpg|thumb|200px|right|RM-200C internals]]The RM&nbsp;200&nbsp;C20 (M8701) is based on a [[R4700]] 133MHz, SNI proprietary [[Wikipedia:ASIC|ASIC]] named ''ASIC PCI 1.1'' and two chips from [[Wikipedia:Intel|Intel]]'s 82430 chipset, the EISA System Controller 82374EB and PCI/EISA Bridge 82375EB. The [[APIC]] of the chipset fortunately isn't wired up.  The onboard [[Wikipedia:Video_Graphics_Array|VGA]] graphics controller is a [[Wikipedia:Cirrus_Logic|Cirrus Logic]] GD&nbsp;5434 with standart VGA connector. RM200 systems have an AMD PCnet 79c970 Ethernet controller and [[Wikipedia:NCR_Corporation|NCR]] 53c810 [[Wikipedia:SCSI|SCSI]] hostadapter onboard which connects to the internal disk drive, SCSI tape and SCSI CDROM. RM&nbsp;200&nbsp;C systems use old 168-pin 5-volt FPM or EDO buffered [[Wikipedia:DIMM|DIMM]]s w/o [[Wikipedia:Serial Presence Detect|SPD]]; 72bit(8*9) ECC/true parity. This kind of DIMMs may be found in the old [[Wikipedia:Power_Macintosh|Power Mac]]s (7100..9600) and some old PC brandname servers issued circa 1997.

-Due to lack of a system in a big endian system for development only the little endian configuration is supported under Linux.  No Linux distribution supports the RM 200 out of the box so any installation will require some Linux skills and an additional Linux system to boot the RM 200 from via network.  Linux support for the RM200 is available since kernel version 2.1 (requires out of tree patches).  Due to a hardware problem for which for a long time no workaround was known Linux 2.2 and 2.3 were unsupported on RM 200; late 2.5 versions fixes these issues.  Latest successfully tested version is 2.6.10-rc3 and is considered stable.

-There are at least 5 different versions of the RM 200 as indicated by a letter trailing the version number.  The '''C''' version can be distinguished from older versions by having both [[wikipedia:Extended_Industry_Standard_Architecture|EISA]] and [[wikipedia:PCI|PCI]] slots on a riser board that sits in the middle of the main board.  The '''C''' version is the only version supported by Linux/MIPS.

 The '''RM 200''' is a MIPS based workstation series originally developed by [[wikipedia:Pyramid Technology|Pyramid]] which got bought out by [[wikipedia:Siemens Nixdorf Informationssysteme|Siemens-Nixdorf]].  The RM 200 was being shipped with [[wikipedia:SINIX|SINIX]] or [[wikipedia:BS2000|BS2000/MIPS]] as the OS in [[Endianess|big endian]] mode and for [[wikipedia:Microsoft_Windows_NT|Windows NT]] in [[Endianess|little endian]] mode.
