LOL!  You just wasted a lot of typing, because you didn't read what I 
wrote very carefully.  I was pointing out that the host adapter does not 
support ATN, and in fact is the same as the one in the Beeb winchester:

In fact you clearly didn't read some of it at all, as most of my post 
was actually pointing out that the E20 (not just the E20S) has no 
Adaptec ACB4000.  Never mind "Look at the Filestore service manual more 
carefully." -- perhaps /you/ should read what is written before you 
reply :-)
