An Educational Suite of Software
     written for Students by  G3NGD
     Please note:  If you already have any of my programs listed below, then you should
     'download' each one again. Over the years, all the programs have been updated and
      in some cases, completely re-written.   The MENU is completely changed and any
      'old versions' will not load the modified software.                              © G3NGD
 

I removed these programs from my previous Website on 'Supanet' when I changed to TalkTalk Broadband. The original programs have not been up-dated, and so my Website Address as shown on my Menu page and other pages is incorrect.
I was thinking of removing these programs from my website, but due to many requests, I have made them available on this website. [I have no intention of updating them in the future].

These programs are given to you "Free of Charge". 
To my knowledge, all these programs work without any problems. They all work fine on my Pentium II
(Windows 98) and also on WINDOWS XP. 

          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\
