I requested voluntary control system producers to help a vehicle manufacturer
a month ago. The original question is enclosed. I have got two answers so far.
They are:
Cortex Ltd./Hungary       willing to desing and manufacture such systems
                          (Tamas Ledezci: h1183led@ella.hu)
Coactive Aesthetics, Inc. offers GCB11 as a base for such a system
SF, CA, USA               (David Gaw: coactive!dgaw@coactive.com)

Hi there!
A message for vehicle control system producers or those who design and make
them quickly:
I am looking a new distributed control system for an in hundreds manufactured
underground heavy-duty vehicle. The basic requirements are as follows:
    -   temperature range -20 to +65 Celsius degrees
    -   automotive 24 VDC supply voltage (18 ... 32 VDC)
    -   master and slave processors connected to a proper network; industrial
        or automotive
    -   slave processors boot from the EPROMs of the master via network (or
        all modules are autonomous and communicate via CAN-bus)
    -   slaves (or modules) can be connected to industrial process I/O signals
        according to the following number of channels per module type:
          Module type                                        1   2   3   4   5
          (1 kHz) binary outputs 24 VDC, 1 A max each        16  8   -   16  -
          PWM outputs 24 VDC, 1 A max each                   -   -   8   4   4
          analog inputs 0-10 VDC (10 bit A/D)                8   16  8   -   -
          frequency counters or timer inputs (10 kHz)        -   -   -   -   4
    -   any 16 (or even 8) bit processor will do, but boards have to run under
        a real-time operative system (like OS-9, Lynx or so) in order to ease
        software development
    -   preferred PCB size is max 100 mm x 160 mm (3.94" x 6.30") and size of
        of one module about two VHS video cassettes (molded in a metal cage);
        connection terminals (a terminal bar) for the I/O signals can be
        outside the module
