PrimeTime IC
The PrimeTime IC combines functions performed by several ICs in previous Macintosh designs. The PrimeTime IC includes data bus buffers for the internal I/O bus I a SWIM II floppy disk controller interface adapters VIA1 and VIA2 address decoding for I/O devices sound control logic and buffers
The PrimeTime IC provides the data bus features of the MC68030 that the MC68040 does not provide. Those features are byte steering, which allows 8-bit and 16-bit devices to be connected to a fixed byte lane, and dynamic bus sizing, which allows software to read and write longwords to 8-bit and 16-bit devices. Those features allow these computers to work with existing I/O software designed for the MC68030.
The PrimeTime IC also contains the sound control logic and the sound input and output buffers. There are three separate buffers—one for sound input and two for stereo sound output—so these computers can record sound input and process sound output simultaneously.
