    Hi!

    To connect two AVM PCI transputer cards only 3 wires and an tiny cut is required.

    Connect Card1 <-> Card2:

    LinkIn1 <-> LinkOut1
    LinkOut1 <-> LinkOut1
    Reset <-> Reset

    On Card2 the Reset has to be disconnected from the XC5202 which normally drives this signal.

    Nevertheless: Linkspeed is only 10Mbit (850kB/s between the cards) and both has only 1MB of ram. But at least with 3 memory cycles which is the fastest possible configuration.

    Today successfully realized by Arachide:

    rspy -l -m
    # Part rt Link0 Link1 Link2 Link3 RAM@cycle
    0 T425C 20 310K 862K ... ... 4K@1,1020@3.
    1 T400C 20 ... 883K ... ... 2K@1,1022@3.

    I followed Mike's method, and here are the pictures of the setting:

    I have a net of two T4xx now. Ready to play with OCCAM...

    Thanks Mike!
