The Exorset was designed by Motorola firstly to be a development kit for the MC6809 and Motorola systems.

It has a built-in green 9'' monochrom screen and two 5''1/4 floppy-drives.
It runs under XDOS (a compatible MDOS operating system).

It is sold with a compiled Basic (BASICM), a text editor and an assembler.

Douro reports us :
The Motorola Exorset-30 has amazing graphic and sound capability. A modified version of this hardware is used in Williams arcade machines !

I worked on this system for 2 1/2 years during 1981-3 to develop 2 products for a motion film industry processing lab. It had no connection to a printer until I hand-made a cable from its motherboard to a Centronics parallel connector. It was slow, the Basic was slow to execute and every sw update had to be burned into several EPROMS each time to try a sw fix/upgrade. But it worked!

I saw one of these in pretty bad shape in a warehouse. How much are these heavy beasts worth??
