Data General Corp has upgraded its family of Unix-based Dasher micros, adding the Dasher/386-25 model, which uses a 25MHz version of the 80386 Intel chip. Data General, which turned the workstations into entry level Unix systems using a 16MHz version of the chip back in January, says that the 386-25 provides source code compatibility for System V Interface Definition applications with its new 88000-based AViiON systems (CI No 1,125). The AT compatible Dasher 386-25 runs Unix 386/ix, has up to 12Mb memory, 64Kb cache, 150Mb SCSI tape drive and allows up to 50 asynchronous serial connections. Configured with 4Mb memory, the system costs $15,480.
