HOWTO: Z80 Emulator - Slackware 14

This HOWTO: will guide you through the process of getting MYZ80 by Simeon Cran running on Slackware 14 under DOSBox.

1. Locate the, and extract the contents to a folder named Z80-Sim.

2. Install DOSBox via


3. Read the Documentation in the Z80-Sim Subdirectory.

4. DOSBox - Command Summary
The following commands can be used in DOSBbox:

intro mount
intro cdrom
intro special
help /all

CNTL F11 Slow down Emulation - Decrease DOSBox Cycles
CNTL F12 Speed up Emulation - Increase DOSBox Cycles
ALT-ENTER Toggle to FULL Screen & Normal
There are several special commands that are shown on the help screens.

5. Testing DOSBox commands and methods.
Let's use this example as a guide for the commands we will need to use to mount and unmount the directory.

I had several recipes that were saved in C:\pw\2_LDK\Cookin on an old Dos machine. I copied the
complete C:\pw folder to /home/larry/C:/. This folder will be mounted as C: Drive in DOSBox so the
EXE, COM, or BAT files can be executed. To mount your C: drive, you will use the mount command to
mount the Linux folder as c and then change to Drive C:\> and execute your old DOS Program.

I executed DOSBox from the Slackware XFCE menu.

Start DOSBox via:

When the dosbox window opened I typed the following to mount a SUBDIRECTORY as Drive C.
So, when I change to Drive C, I am really pointing at /home/larry/pw

DOSBox positions you at Drive z:


    mount c ~/C:
    cd pw

From within pw I just used a normal program exit.

Before you can un-mount the drive you must change back to drive z: then you can issue the un-mount command.
To un-mount C: and exit DOSBOX use the following commands:


    mount -u c

6. Running Z80 Emulator
Start DOSBox via:

DOSBox will come up and you will be on Drive z:
(Type the following commands adjusting for the specific Emulator.)


    mount c ~/path/to/Z80-Sim
    dir /p

There are two programs (IMPORT.COM & EXPORT.COM) that allow you to import and export files into the DSK
images. I wanted to use Nulu12 and Nsweep because those were not included. I found the files on the
Internet, but I needed to extract them from a LBR file. That led to a search for UNARC16.ARK. I found
the file and finally found instructions about just renaming it to UNARC16.COM, and then executing the
file since it was a Self Extracting type file. That allowed me to extract Nulu12 and Nsweep from some
of the ARC type files. Then I just imported and into the Z80 Emulator.
That allowed me to search more LBR files, including the myz80com.lbr file.

Other Z80 CP/M Commands:

dir B:
user 1
dir B:
user 2
dir C:
user 0
CNTL C is used to reload the Disk Directory

So, the whole world of CP/M is now available for your work or play. Be sure to check out all the
other nice utilities from the CP/M Days.

When you are finished with the Emulator use EXIT to exit. Then you need to un-mount the subdirectory
and exit the Terminal Window. Here are the commands.


    mount -u c

If your Terminal should hang, you can do the following to stop the process and close the Terminal.

q    or  CNTL C

Look for the Process number associated with DosBox. Assume 6545. Use the following command to Terminate
the Process.


kill -9 6545

Hi Larry

Would you consider adding this HOWTO as a new page in the Slackware Documentation Project? Possibly in a new "games" section?


lkraemer 10-16-2012 04:51 PM

I'd be glad to add this [HOWTO], but I've never done anything like that yet. Is there information on how to proceed?

Are you sure you want it under Games? Wouldn't it be under Software or Application as it's CP/M (Control Program for Microprocessors).

An emulators section would have been wiser to suggest :-) would be a good place to start editing.

You can always read the guides and other helpful texts at or or .
The first thing to do would be to create an account of course:

If you need help with getting the page off the ground initially, yell for help in the mailing list: or just email me (or write a comment in your own thread here at LQ).
