NBserver developed by Bas Boetekees.

Back in 1993 most members had a dos machine and the NewBrains were starting to catch dust or sometimes they were used for a very specific task. It became interesting to see if the software could be transferred to an MS-dos machine. First for backup, later to see if a dos machine could be used as a server for the NewBrain.

The final result was a program called "NBserver v3" the program was finalised in1995. his peace of software will only work under real dos. (I have tried  Windows 98, 2000 en XP , but I can't get it to work. not even when I boot the machine in dos mode and / or safe mode.)

If you want to use NBserver all you are going to need is a cable from the NewBrain comms port to the RS-232 port of a dos machine. In case you would like to connect more then one NewBrain to a dos machine you are going to need quit a bit of hardware. Please contact the NewBrain GG and we will see if we can find the schematics for the hardware.

 De colour is only important if you would be lucky enough to have an original comms cable. If you haven't, don't worry it is easy enough to make a cable yourself. All you need is a double female strip and a 9 pin db-connector (female) + a piece of wire (every electronic shop will have it).

 

How to use NBserver?

  1. connect the NewBrain with the dos machine and turn both machines on.
  2. start nbserv_3 on the dos machine.
  3. Type on the NewBrain:     OPEN #0,9  and if everything is going ok the NewBrain will start by loading the header and then a menu in which you can choose a basic program.
  4. Choose and load the program
  5. move the cursor to the first line and press enter.

Before you use  NBserv for the first time, you must change some parameters in the file NBSERVER.INI make users = 1 and and change the TIJD according to the processor and the COM depending on the com port.

Some key that are used within the program:

D synchronise display.
I show settings.
R reset the number of used files per user.
F1 help in Dutch
F5 2 window toolbox
ESC the end.
