Berty

Overview

Berty is a DOS-based Artificial Neural Network (ANN) simulator using weighted cells. It displays cell activity in real-time with moveable 'viewports', 'eeg' trace probes, and stimulus regions.

It is not intended for the advanced ANN specialist (no learning methods or complex maths!), but provides an arena for playing with cells and studying cell patterns and growth when subjected to stimuli. Just set up a network, switch on and probe around for activity.

Features

  • Large Networks - Only limited by size of extended RAM
  • High Speed - Program written in machine code
  • Realtime I/P - Cell stimuli via key presses
  • Graphical O/P - 2D movable viewports, 'Eeg' traces
  • Simple PC Spec - DOS-based, 80386 upwards
  • 3D Network - Cells occupy 3D volume, so have physical 'neighbours'
  • Growth algorithms

Minimum system requirements

386 processor, 640x480 vga display
200Kb conventional memory, 500Kb extended memory (XMS V3.00)
DOS (tested on V6 & Windows 95 DOS, should run on V5, possibly earlier)

Windows 95
Either Shutdown and Restart in MS-DOS Mode or run the program and let Windows create a MS-DOS shortcut for it.

Windows 98
Either Shutdown and Restart in MS-DOS Mode or create a shortcut/PIF
file for the Bertynnn.exe file as follows:-
  • Right-click the BERTYnnn.EXE file, click Properties, Program, Advanced
  • Check 'MS-DOS mode', select 'Specify a new MS-DOS configuration'
  • Add the following lines to CONFIG.SYS, replacing 'C:\Windows' as necessary for your PC:-
    DOS=HIGH,UMB
    DEVICE=C:\Windows\HIMEM.SYS

Windows ME & XP
Program will not run unless you can somehow boot your PC into MS-DOS mode, e.g. via a floppy or dual-boot. The himem.sys driver must be present in your config.sys file. Please note that the program uses DOS routines to save/write files to disc. These work ok with FAT partitions, but have not been tested with NTFS partitions.
!!! Saving/writing files to an NTFS partition is at your own risk !!!

Downloads

Berty v003: exe  zip - all programs are held on the pCloud.com storage site. If there are problems downloading, check your computer's access or contact me via email address at bottom of this page.

The demo version is free, but if you pass it on please keep the package intact.

Note this download is a demo version; please contact me for the full version which is also free; see Program Versions for differences between them.

Installing

  • Download either the self-extracting exe file, or the zip file if you have an unzipper such as WinZip.
  • Extract/unzip into a folder of your choice (which must be in DOS 8.3 format), e.g. C:\Berty
  • The following files will be created:-
    Readme.txt - overview & installation details
    Bertynnn.exe - main executable, version nnn
    Demo*.brn - a set of demo files
    Startup.brn - initialisation file loaded at start-up
This is a DOS-based program, so please note the system requirements above. To start the program, run or double-click the executable:  Bertynnn.exe (you can 'right-click' it and click 'Send To, Desktop' to create a shortcut for future use). When Berty is running, press the 'h' key for further online help, or contact me if you have any problems.

Uninstalling

Delete the above files/folders.
