Superbrain

Superbrain

The Superbrain was an integrated system with keyboard, display and disc drives. The system used two Z80A microprocessors at 4 MHz, one for the main processing, and the other for peripheral activities.

The dual 5" floppy disc units could be 2x170 KB (single side), 2x340 KB (DS), and a 10 MB CompuStar hard disk could be added.

The SuperBrain was sold with the CP/M operating system, Microsoft Basic, an


8080 assembler and Microsoft Cobol 74.

The SuperBrain II appeared in 1982. It offered a faster and enhanced disk operating system, new video visual attributes and better graphics capabilities. The SuperBrain and SuperBrain II were 5 floppy disk based CP/M machines. Four models in each category:
-
10 (no drives - network only),
-
Jr 170K,
-
QD 340K,
-
SD 780K.
Each could have one or two drives. Intertec did not sell or support a hard drive or an S-100 bus for these machines. The network version of the SuperBrain was called CompuStar. The network was a parallel cable design with large gray cables about " diameter. CompuStar had three "file servers" that accepted up to 255 machines:
- DSS-10 10MB 8" Winchester drive,
- CDC 96MB, 80MB fixed with a 16MB removable platter,
- Priam 144MB 14" platter winchester.
Intertec manufactured the controllers for the last two and an enclosure/PS for the Priam. CDC had to go on-site to install the 96MB.
