Single Board Computer Basics
The Single Board Computer used in Centaurus Prime Gateways is the Ether 6
manufactured by JK Microsystems. It is made in the United States of America.
The controller is based on an Intel 386Ex processor running at 25Mhz. It is equipped
with 1 megabyte of static ram organized as 512K 16-bit words. Also included are 512K
bytes of flash memory organized as DOS drives A and B. A 40 Megabyte M-Systems
DiskOnChip is added to the 32-pin DIP socket on the controller board, and acts as
drive C: There is a switching power converter on the controller, which can accept 7-34
volts DC. Nominal current consumption is 250mA at 12 volts with 10Base-T
Ethernet selected.
