... It uses the transformation parameters computed by the command ASTROMET/TRANSFORM . ... ASTROMET/COMPUTE computes the RA,Dec coordinates from X,Y coordinates directly from the transformation parameters, while it obtains X,Y from the RA,Dec ones in an iterative manner. Also note that the equinox of the computed coordinates is the same as the standard star catalogue (which is NOT necessarily the same as its epoch) and is 2000.0 in case the PPM catalogue is used. ...

... If you want good analog I/O, you can wire up ADC and/or DAC chips to the parallel port (hint: for power, use the game port connector or a spare disk drive power connector wired to outside the computer case, unless you have a low-power device and can use the parallel port itself for power, or use an external power supply), or buy an AD/DA card (most of the older/slower ones are controlled by I/O ports). ...
