Hey Ian,
Yes it can be done........ maybe........if........ hehehe
I dont have anything hooked up at the moment for the OLD style serial MB, (since your using the vb that accesses it, I am thinking that is what your using).
The Brain that is attached, in THEORY........ should do what you want, with the following caviot.
what it does is this, if SNPMB inputs 0 and 1, are NOT equal that sets the var to true or 1, if equal it is set to 0.
on the second line, I run a formula that will multiply the Var times the input0, so if the rung above is true, then the var
multiplies the input times 1, then sends it out to SNPMB output 1. But if your VAR is 0, i.e. if inputs 0 and 1 above are eqaul
then your output 1 will always be forced to 0............. dont know if that would be a problem for you or not.
