INT 80 - BusLogic BT-946C PCI SCSI(Small Computer Systems Interface) A system-independent expansion bus typically used to connect hard disks, tape drives, and CD-ROMs to a computer. A host adapter connects the SCSI bus to the computer's own bus. See also ESDI, IDE. Adapter - SCRATCHPAD RAM(Random Access Memory) See also DRAM, SRAM. (NOT A VECTOR!) Note: the factory-default location for the eight bytes of scratchpad RAM(Random Access Memory) See also DRAM, SRAM. needed by the SCSI(Small Computer Systems Interface) A system-independent expansion bus typically used to connect hard disks, tape drives, and CD-ROMs to a computer.
