Software Policy: We do not sell or distribute Fadal copyrighted software. Boards such as the 1400 CPU board and the 1010 Axis controller board requires Fadal copyrighted software. It is best to retain and use your original Eproms and avoid introducing software compatibility issues. Contact a Fadal authorized Eprom supplier, they provide Eprom upgrade exchanges, usually for free.


About the Main CPU Boards:
Throughout the history of producing machines, there have been 6 main cpu boards.  Each identified by a dash number.  The very first machine (VMC45) used the 1400-1 board as well as the first VMC40s.  The 1400-2 was the second generation control board and each new revision was added as new INTEL microprocessors became available.

The 1400 board is the Central Processing Unit of the CNC control. All CPU boards come with 38K of battery backed memory. This memory is used to store the following:
   • CNC Part Program
   • Tool Data – both Length and Diameter
   • Fixture Offset Data
   • SETP parameters
   • Backlash
The CPU board executes the part program by issuing commands to the other boards and monitors the inputs from the other boards and proceeds as required by program and external information.

The Fadal CPUs are as follows:
  • 1400-1 – This was the first CPU, it is very rare, if you have problems with one please call for assistance.

  • 1400-2 – Served many years as the CPU. Can be in any of the first 5 slots however try to keep them in slot 5. Has a Program Module (1610-0) plugged into it, this module provides the operating code for the CPU. For optional memory expansion, memory expansion boards (1460-1) were added in slots 1 to 4. Each board contained 128K. Up to three memory boards could be added for a total of 422K.

  • 1400-3 – This CPU board was an interim CPU between the 1400-2 and the 1400-4. It has to be in slot 5 because of the bus board which connects the Computer Interface Board and the CPU. This CPU uses the Computer Interface for the video signal. This CPU uses the Program Module (1610-1) and the Expanded Memory Boards that plug into the CPU Board. (J4-J5) Up to 422K Expanded Memory total.

 • 1400-4 – This CPU board was used for years. It has to be in slot 5 because of the processor bus board which connects the Computer Interface Board (1030), the Video Graphics Board (1420-4) and the CPU. This CPU uses the Video Graphics for the video signal and the graphics. This CPU uses the Program Module (1610-1) and the Expanded Memory Boards that plug into the CPU Board. (J4-J5) Up to 422K Expanded Memory total.

 • 1400-5 - This CPU board is the current CPU. It has to be in slot 5 because of the processor bus board which connects the Computer Interface Board (1030), the Video Graphics Board (1420) and the CPU. This CPU uses the Video Graphics for the video signal and the graphics. This CPU uses the Program Module (1610-1) and the Expanded Memory Boards that plug into the CPU Board. (J4-J5) Up to 16MB Expanded Memory total.
