+NOTE: Lynx support is currently flagged as experimental due to lack of
+      testing / test hardware.
+
+Memory:
+The machines use dedicated memory boards. These boards live on a 128 bit 
+C-bus shared with the CPU boards. DemiSable supports up to 1Gb, Sable up 
+to 2Gb. One of the memory bus slots can either hold a CPU or a memory card.
+Some memory board modules house SIMMs. There are also memory modules that
+have soldered-on memory chips instead of SIMMs. SIMM boards are used in sets 
+of eight 72-pin 36 bit FPM memory of 70ns or faster. SIMM types supported 
+are 1Mb x36 bit (4 Mbyte) and 4Mb x36 bit (16 Mbyte). Each memory board 
+can house 4 banks of SIMMs. SIMM sizes can not be mixed on a single memory
+board.
+
+Embedded SCSI:
+Both Sable, DemiSable and Lynx have NCR810 based Fast SCSI onboard.
+
+Expansion:
+DemiSable has 7 EISA slots and 3 PCI slots. Sable has 8 EISA and 3 PCI
+slots. Lynx, being newer, has 8 PCI and 3 EISA slots. Make sure you run the
+EISA Configuration Utility (from floppy) when adding/change expansion cards
+in EISA slots.
+

+19" rack. This is medium iron, not a hobbyist system. 
+These are multi-CPU machines, up to 4 CPUs can be in a single

+at the bottom of the pedestal. The Rawhides intended for the NT market are
+designated DIGITAL Server 7300 (5/400 CPU), DIGITAL Server 7305 (5/533 CPU).
+A trailing R on the partnumber means a rackmount variant.

+- memory bus: 128 bit with ECC
+- embedded floppy controller
+- 2 serial ports
+- 1 parallel port
+- PS/2 style keyboard & mouse port
+
+Memory:
+Rawhide uses a maximum of 8 RAM modules. These modules are used in pairs
+and supply 72 bits to the bus (this includes ECC bits). Memory can be EDO
+RAM or synchronous DRAM. A fully populated Rawhide has 4 pairs of memory
+modules. Given the choice use SDRAM for best performance. The highest 
+capacity memory board must be in memory slot 0. A mix of memory board sizes
+is allowed. A mix of EDO and SDRAM is also reported as working (assuming you
+don't try to mix EDO and SDRAM in one module pair).
+
+Embedded SCSI:
+Rawhide has a embedded NCR810 Fast SCSI bus.
+
+Expansion:
+Rawhides are available with a 8 64-bit PCI / 3 EISA slot expansion backplanes
+(called 'Saddle' modules). There are 2 seperate PCI buses, PCI0 and PCI1.
+PCI0 has 1 dedicated PCI slot and (shared) 3 PCI/EISA slots. PCI0 also has a
+PCI/EISA bridge that drives things like the serial and parallel ports,
+keyboard/mouse etc. PCI1 has 4 PCI slots and an NCR810 SCSI chip.
+
+	NOTE: EISA slots are currently unsupported.

+Power:
+The system employs an I2C based power controller system. If you want to be
+sure all power is removed from the system pull the mains cables from the
+system.
