Callan Data Systems - Unistar

Unistar

After initial success building a Multibus chassis with a self-contained VT-100-compatible CRT display terminal to OEMs, the company designed and built desktop workstations named Unistar using the Sun-1 board, which was based on the Motorola 68000 CPU, and which ran UNIX licensed from AT&T. The manufacturing consisted of building the chassis, power supplies, motherboard, and a few critical Multibus boards such as the CPU, memory, and floppy and hard drive controllers. Other peripheral boards such as an Ethernet controller were purchased from other OEMs. The software development consisted chiefly of writing device drivers for the integrated system, based on the UNIX kernel, and integrating third-party applications for resale to customers. Investment totaled $10 million, raised from the founders and from venture capital. Employment peaked in 1984 at 80 persons.

Other firms at the time were competing to build the first commercial UNIX workstations based on inexpensive microprocessor-based Multibus-single-board CPUs. Among these competitors were Sun Microsystems (which based their initial enormous success on their original similar SUN-based workstation), HP, Apollo, Ithaca Intersystems and Wicat.

Callan sold about a thousand units in various models, including the Unistar 100, 200, and 300. The 100 and 200 models, first delivered in 1982, used the desktop chassis/CRT combination with Multibus backplane, with a list price of about $12,000. The 300 model of 1985 was a floor-standing chassis using dumb terminals, and sold for about $20,000. CPU speeds were typically 8 MHz, with 256KB to 2MB of main memory, and from 10MB to 43MB of hard disk storage. A 400 model using 360MB Fujitsu hard drives was prototyped. UNIX V7 was originally ported to the Unistars, and later UNIX System V, all the Uniplus ports provided by UniSoft.
