There are two variants of the microSPARC-II (code-named Swift): the microSPARC-II and microSPARC-IIep. The microSPARC-II is used in the SPARCstation 5. The microSPARC-IIep is a 100 MHz microSPARC-II with an integrated PCI controller for embedded systems. It was developed and fabricated by LSI Logic for Sun, and used in their JavaStationNetwork Computer.
