if i remember correctly a transistor is needed to pull the prop reset low when using a uart. Is this right?
Does anyone happen to have the propplug schematic handy?

    As was mentioned already, I would look at the software model first and design back from there. For a model based on communicating sequential processes, the topology probably matters the least, because the programmer must explicitly designate the communication paths. The recommendation for the Linda system is multiple buses, with an even number of buses connecting to each node. These are orthogonal rather than heirarchical buses. Linda is interesting in that you don't explicitly direct things to run on a particular node, theorectically you could write a program and it would run on any system that had enough memory to handle it. I think the preferred hardware for distributed shared memory is a heirarchical system of shared buses. I've mentioned elsewhere Jeff Fox' super-simple implementation of distributed shared memory in Forth (F*). It adds only one word to the Forth wordset.
