Data General Corp yesterday added the AV 100 graphics workstation to its AViiON RISC Unix line, claiming that at $4,000, it offers the best price-performance ratio of any RISC-based desktop in the industry. Rated at 17 MIPS, the 88000 RISC-based AV 100 is claimed to be more powerful and $1,000 less expensive than its closest RISC rival, Sun Microsystem’s SLC, which runs at 12.5 MIPS. The AV 100 uses a 16MHz Motorola 88100 and the price includes 8Mb memory, 20 monochrome monitor, SCSI and Ethernet interfaces and two serial ports. It takes up to 16Mb memory and up to 4Gb of external disk.
