The IBM 709 (a vacuum tube machine) introduced the concept of data
channels (now called DMA) in a commercial product ca. 1957. This
included interruptions, referred to in that architecture as traps. The
current instruction address was stored in a fixed location and control
was given to the channel trap routine which stored the registers and
processed the interruption. The instruction set included the TTR (TRAP
TRANSFER) instruction used to return from interruptions. It could not
be trapped, so the next interruption would occur back in the user
program rather than in the trap routine.
