Abstract : JOSS is a time-shared computer system that provides for the solution of numerical problems via an easily learned language at remote typewriter consoles. The PDP-6 hardware used to implement JOSS consists of 32,000 words of 1.75m sec core memory, a 1-million-word 4m sec drum, a 6-million-word discfile, and various peripheral devices. A special data relocation mode for memory references has been added to facilitate interpretation of JOSS programs. The JOSS consoles, built around a Selectric I/0 typewriter, were specially manufactured to RAND specifications. Features include full duplex signaling, line parity checking, a page eject mechanism, and several buttons and lights to control and report console status. The stand-alone JOSS software consists of the JOSS language interpreter and its arithmetic subroutines, a monitor for user scheduling and resource allocation, and I/0 routines for the disc, drum, consoles, and other peripheral devices. JOSS service is currently available to nearly 500 users through 34 consoles, six of which are remote to RAND operating over both private and dataphone lines. (Author)
