I was just looking over Sundance's Serial TRAM and it doesnt even use a
transputer. It just uses C011s to handle the links. Wouldnt that be easier???
There would be no need to get any spare transputers (and they are hard to source
these days). The SMT220 seems to be a very easy design. As John said, it would
be really neat if it can handle modems, etc like a true PC-based serial port...
