Some of the Computer Conservation Society’s computer emulators are MS-DOS or PC-DOS
programs written as long ago as the 1980s and 1990s.
They may not run (without assistance) on current versions of Microsoft Windows.
There are two problems:
16-bit programs are incompatible with 64-bit versions of Windows.
(They may still run on 32-bit versions of Windows.)
Some programs require “fullscreen mode” which is no longer supported.
You may get an error messages like one of these:
(Attempting to run in cmd.exe on 64-bit Windows 10)
(Attempting to run in cmd.exe on 32-bit Windows 7)
(Attempting to run as a Windows executable file in 64-bit Windows 10)
(See Microsoft knowledgebase article:
There is an easy way round these problems:
DOSBox is a freeware DOS emulator written for running classic computer games.
It works equally well for computer emulators.
It appears as a window containing a DOS command line interpreter.
DOSBox is well documented on the web.
There are examples of its use on YouTube and a full User Manual included in the download.
Installing DOSBox for running CCS emulators
Create a folder to accommodate the troublesome emulator(s):
- e.g. A folder called “DOSems” on the desktop.
(Folder names are not significant, so long as they are used consistently,
so you can choose a different one if you wish.)
Download and install DOSBox from www.dosbox.com:
- Click on “Downloads” (just under the banner heading).
- In the “DOSBox (specific versions)” panel,
click on “Windows” to download the installer file
Save it to your desktop or Downloads folder.
(0.74 is the DOSBox version number at time of writing.)
- Double-click the downloaded installer file and follow the onscreen instructions to
Mount the folder created in step 1 as a virtual hard drive in DOSBox:
- From the Windows Start button, find “DOSBox-0.74” in
“All Apps” (or “All Programs”),
click to expand it and select “DOSBox 0.74 Options”
(or “Options” and then “DOSBox 0.74 Options”).
The configuration file opens in Notepad.
- Scroll down to the very end of the file where you’ll find:
- # Lines in this section will be run at startup.
- # You can put your MOUNT lines here.
- Add three more lines:
- MOUNT C C:\Users\Steve\Desktop\DOSems
- KEYB UK
Modify this example so that the first line mounts your new folder on what DOSBox
regards as its “C: drive”.
(If you aren't sure of the path name, right-click the folder and select
‘Properties’ so that the ‘Location’ is displayed.)
The second line configures DOSBox for a UK keyboard.
For other countries see
(Note that KEYB is in upper case.)
The third line changes directory from the default Z:\> to C:\>.
- Finally, save the configuration file (File menu > Save). DOSBox is now ready to use.
