Pete´s virtual museum




Time warp back to the 70´s.

You are at work. New job, new project, new machines. It´s strange. All people around you feel somehow distracted. Last week they seemed normal, but today...
It´s like world is changing. Talking nothing but some new western movie which is now running on theatres. And it has an odd name :"Star Wars". Are they grazy or something? Well, better get back to work.

FDOS Operating Instructions for EXORciser in a Nutshell

Usage of EXORciser is mainly dedicated for research, theses and special works. If there's any machine time left over, it can be used also for other purposes. These instructions are meant for first timers, who have to ask permission from the assistant to use the machine.

1. - 5. working with MDOS

1. Check that everything is plugged in and turn on the EXORdisk, EXORciser and Teletype.

2. Press RESTART. The system will start up to initial state showing prompt EXBUG 1.2.

3. You are now in EXBUG 1.2. monitor program and can write commands for it. Type MAID after the text.

4. You are now in EXBUG's MAID functions and a * is echoed to show that. Now you can change the contents of memory locations, run programs and other MAID functions.

5. Start up the disk operating system by writing E800;G after the star. EXORciser will now load up the control program and will show excalamtaion mark ! as the FDOS prompt.

6. You are now in FDOS operating system and can fix source codes, compile your program to machine language and load the compiled version to EXORciser's RAM memory.

7. Write EDIT,,NAME after the exclamation mark. Note: the name you must invent yourself. Command in FDOS is finished by pressing RETURN.

8. Now you are in EDITOR-program, which is shown with @-mark. Here you can handily write your program in disk with "I text @@" command-format. Learn the commands for Editor. You can exit from the Editor by writing "E@@" command.

9. The machine writes an exclamation mark, so it is in FDOS. Now you can compile your program with command ASM, 2, NAME 1, NAME. When the machine has finished, it will again show the exclamation mark.

10. If there were bugs in the program, go back to the editor with command EDIT, NAME, NAM to fix them. Your first task is now to write A@@, i.e. bring the information from editor's buffer for editing. After this return to FDOS and compile the program again. Always remember to use a new name, and the useless files have to be deleted.

11. If the compilation succeeded, load the program to EXORciser RAM-memory with command "LOAD, NAME 1"

12. The machine is prompting EXBUG, type MAID.

13. The machine is prompting *, i.e. you are in MAID functions. Run your program by writing the starting address of the program and semicolon G, e.g. 100; G

14. Finally turn off the machines.

Using of floppy disks

1. Turn on the EXORdisk.

2. Open the disk hatch.

3. Push in the disk through the hatch, side with the label on top. Push the disk to the end and behind the stopper. Close the hatch.

4. Never turn off the EXORdisk when there is a disk inside, nor the other way round.

MDOS directory listing: Type DIR or if you use 2 or more disks DIR :1 (drive 1 etc.), DIR ;SA or DIR :1;SA


Editor note: People´s who´s don´t see Star Wars then or watch it later years to come, are greater risk to suffer dull life and lack of imagination.
