The technical memorandum: A Kernel Programming Interface for Precision Time Signals (PostScript) describes a proposed programming interface for external precision time signals, such as the pulse-per-second (PPS) signal generated by some radio clocks and cesium oscillators. ... The hardware to do this requires only a serial port and a modem control lead, such as the data carrier detect (DCD) lead, which can be driven by an external source via a level converter/pulse generator. ...

SPTIME takes an input source spectrum, either a reference blackbody, power law, or a user spectrum, a background ``sky'', observing parameters such as exposure time, central wavelength, seeing, airmass, and moon phase, instrument parameters such as aperture sizes and detector binning, a description of the spectrograph, and desired output. ...

Target Acquisition Reference Information . There are limits to the brightest and bluest stars that can be acquired with mirrors N1 and N2 because of the very high fluxes of these objects. Figure 7.3 on page 91 shows the limits for these two mirrors as set in the Constraints and Restrictions Document (CARD). ... Once you have predicted an acquisition count rate, you then determine the integration time per dwell point during the target acquisition: STEP-TIME. ... STEP-TIME Constraints . ...

... Of course the ISA-ethernet-cards still work, but people are asking for PCI-based ones. The author of many (if not most) ethernet- drivers said the following some time ago (unfortunately I have not managed to contact him about new information): . ... The Linux driver for this card is not yet part of the release kernel, but is available from http://cesdis.gsfc.nasa.gov/linux/drivers/vortex.html and can be patched into the later 1.2.x kernels (as well as 1.3.x) without much difficulty. ...
