65, The bit-planes for a full-screen-sized, interlaced display are 400, rather than 200, lines long. Assuming that the playfield in memory is the normal 320 pixels wide, data for the interlaced picture begins at the following locations (these are all byte addresses): Line 1 S…

166, NOISE REDUCTION To reduce noise levels and produce an accurate sound, try to use the full range of -128 to 127 when you represent a waveform. This reduces how much noise (quantization error) will be added to the signal by using more bits of precis…

96, SUMMARY OF PLAYFIELD REGISTERS This section summarizes the registers used in this chapter and the meaning of their bit settings. The color registers are summarized in the next section. See appendix A for a summary of all registers. BPLCONO - Bit Plane Contr…

239, Control of the disk operations IS distributed among several registers in the system. Among the control types are o Selection, motor control, sensing o Disk DMA channel control, DMA enable. o Disk data read/write. o Disk format control. o Interrupts generate…
