Oh yes. I've got a advertising broacher for that somewhere.
 
I didn't like the Torch copros as they didn't use the Tube
protocol properly, they bypassed it and played with the Tube I/O
address space directly. I had no objection to replacing the ULA
with their own circuitry, I just would have likes them to have it
look the same from the hardware point of view, ie &FFE5 transfer
bytes between processors, etc.
