Abstract

We have recently acquired a DEC VAX 11/730 computer with partial support from an International Halley Watch grant from NASA/JPL. The VAX 11/730 has a 1 Mb CPU with a floating-point processor. We hope to expand the CPU to 4-5 Mb in the next year. Peripherals include two disk drives: DEC RL02 (10.4 Mb) and an R80 (121 Mb). The VAX/VMS Version 3.1 operating system takes up about 25 Mb on the R80 disk drive. Fortran 77 has. also been added. System up-dates and software drivers are added via a TU58 tape cassette drive. At present, we have one 9-track tape drive, a Kennedy Model 9100, which runs at 75 inch/sec on 800 or 1600 bpi. We have two VTl00's with Retrographics (emulating the Tektronix 4010). An LA120 (Decwriter III) serves as a operating console and printer (180 characters/sec). In addition, we have a Versatec V-80 printer-plotter.
