! Provides the number of external cycles that need to begin from now in order to get at least @c internal_cycles into the future. */

! @returns @c true if this partial machine cycle completes one of the documented full machine cycles; @c false otherwise. */

! Equivalent to set_value16((v << 8) | 0x00ff). */

Shifts two pixels.

@returns The bits of @c input with a 0 bit inserted between each and keeping the least-significant bit in its original position. i.e. if @c input is

Gets the current value of the status register.

@returns The linear address for offest @c address within the segment described by this descriptor.

@returns The address size for this instruction; will always be 16-bit for instructions decoded by a 16-bit decoder but can be 16- or 32-bit for instru

Used by both DMA devices and by the CGA and MDA cards to set up their base pointers. @c address is always physical.

@returns @c 1 if carry is set; @c 0 otherwise.

Empties the PCMSegment.

! Converts from a source data block to one properly encoded for the drive type. Expected usage: const size_t source_address = mapper.to_sourc

! @returns the two quadrature channels — bit 0 is the 'primary' channel (i.e. the one that can be monitored to observe velocity) and bit 1 is

! Gets the previously set level of an output line. */

! @returns the expected length of the scan period (excluding retrace). */

Obtains the output source.

@returns The current value of the CRC.

! @returns the width of the texture target. */

! @returns Negative log sin of x, assuming a 1024-unit circle. */
