Note:  this entire suite of Educational Software will fit on one  Floppy Disk.

I suggest that you  initially download the programs onto a Floppy Disk.   By doing so,  you won't overwrite any
programs already on your Hard Drive bearing the same file name. When you click on the link, you will be asked
if you wish to open or save the file. Select Floppy Disk using your mouse, having first put a Floppy Disk in your drive.
If you like the programs,  you may transfer them to your Hard Drive, saving them in a directory not containing similar 
file names. Don't rename the filenames, as you will not be able to select the programs when using the MENU BAR.
 

           Important information for anyone using my software.
Although my software  is written for DOS, it will all work well in windows 95, 98, XP.
If anyone finds that certain symbols don't appear as expected - for example a rho, pi, or the ohm symbol, then it is likely that your computer has been set-up in 'multilingual language' instead of UK/US language. 
It is simple to correct for this without giving rise to other problems.
Load your AUTOEXEC.BAT file into 'notepad' and change the codepage from 850 to 437 then save it back to the hard drive. Re-boot your computer and the programs should work correctly. 

Example of AUTOEXEC.BAT  file to be changed.
REM [Display]
mode con codepage prepare=((437)  c:\windows\COMMAND\ega.cpi)
mode con codepage select=437
keyb uk,,c:\windows\COMMAND\keyboard.sys
PATH C:\BITWARE\
