Yes, but it wasn't in the coco's, any of them.  I looked at it once, and 
it hooks into the 6809 pretty solidly and it would take quite a bit of 
work to hack it in I think.  Unforch, I don't recall the number of it 
at this late date, that itch was scratched back in the late 80's.  
Several moves etc have occured since and I don't recall coming across 
anything like that in the last 16 years I've lived here.

People having trouble with vz bouncing email to me should add the word
'online' between the 'verizon', and the dot which bypasses vz's
stupid bounce rules.  I do use spamassassin too. :-)
