| Abstract: | A hardware-software extension to the DEC LPS 11 facilitates interfacing the PDP 11 to external instruments. The hardware component consists of eight relay drivers and relays, four contact conditioners, and an interrupt pulse former. FORTRAN-callable RT-11 MACRO subroutines control the device, service interrupts, and transfer control to FORTRAN completion routines. |
