When writting a single byte to external memory, what happens with the rest of the MemADxx lines, are they in tristate or driven by the Tp to a known value? Thanks in advance. -- Dario.

Thanks in advance. >-- >Dario. The transputer reference manual (Oct 1986, pg 46) says: "A seperate MemWrB signal is provided for each byte. A word (32 bit ??) write uses all the notMemWrB signals. If a particular byte is not to be written, then the corresponding data outputs are tristated" So, yes, they are tristated. Ravi Masand bellcore!thumper!rtm1
