Synchronous Backplane Interconnect
Encyclopedia
The Synchronous Backplane Interconnect (SBI) was the internal processor-memory bus used by early VAX
computers manufactured by the Digital Equipment Corporation
of Maynard, Massachusetts
.
The bus was implemented using Schottky
TTL
logic levels and allowed multiprocessor
operation.
VAX
VAX was an instruction set architecture developed by Digital Equipment Corporation in the mid-1970s. A 32-bit complex instruction set computer ISA, it was designed to extend or replace DEC's various Programmed Data Processor ISAs...

Schottky transistor
A Schottky transistor is a combination of a transistor and a Schottky diode that prevents the transistor from saturating by diverting the excessive input current. It is also called a Schottky-clamped transistor.-Mechanism:...

Transistor-transistor logic
Transistor–transistor logic is a class of digital circuits built from bipolar junction transistors and resistors. It is called transistor–transistor logic because both the logic gating function and the amplifying function are performed by transistors .TTL is notable for being a widespread...
