EXTENSIS
EX3000

The EX3000 Computer, a typical success(?) saga of the early personal computer days.

The Extensis Corp. EX3000 computer pulled together four emerging technologies; multiprocessor supercomputers, 8 bit microprocessors, the S100 bus standard and multiprocessor, multitasking multiuser operating systems.

The hardware of the EX3000 system consists of subsystems and boards. Three subsystems were provided :

FOS100 > Floppy disk subsystem (from one to four MB)
MTS100 > Multiple terminal system with 8 or more independant RS232c serial interfaces
TPS100 > Terminal / Operator Processor Subsystem with keyboard, CRT, RS232c and expanded video attributes.

And the following boards were included in the EX3000 :

RM64A > Memory board with 16 KB RAM
MM16 > Memory Management board with bankswitching up to 1 MB.
MPU8085 > 8085 Central processor with onboard PROM
MPU800 > Optional Z80 CPU with onboard PROM

The operating system, EMOS, is a multi tasking, multi users operating system which provides memory protection for each user. It can handle the two processors simultaneously. Several languages were developped for this operating system : Extended Basic, Cobol and ANSI Fortran.



We need more info about this console ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.
