Engineers at Radstone Technology Corp. of Montvale, N.J., are offering a PowerPC Reference Platform-based single-slot VME64 single-board computer with PowerPC 750 and G4 microprocessors in air- and conduction-cooled versions. Called the PPC4, the board offers dedicated Level 2 cache support, and more DRAM, faster access, and faster Flash memory than existing Radstone PPC1A and PPC2A boards, as well as added EEPROM, 100BaseT Ethernet support, and slots for PCI mezzanine cards.
