Tekram DC-320/DC-820 SCSI Controllers
|
||||
|
||||
These EISA host adapters have, in addition to internal and external
|
||||
SCSI and floppy disk connectors, LED and "SPKER" jumper headers. The
|
||||
DC-820 and DC-820B also have four SIMM slots in addition to 64K of
|
||||
static RAM on board. The DC-320 and DC-320B only have 16K of SRAM.
|
||||
|
||||
The DC-820B has an ASIC in place of the 11 PLDs used by the DC-820.
