Oh my!  Eric,  this just becomes more and more silly!
Yes,  I can work pretty well with external perf board;
have done that a bit already since my vision went South, hi.

I have no idea what you mean about "block all signals but...";
and what is this about "wire has to be null-modem -- the 
clock is DTE -- to connect to your computer."

I am starting to believe I am in over my head;  but,  I have
already put the hp Z3801A on order!

Is there some less costly solution for me?  I mean something
I can do that won't require my XYL getting involved?  She
is a great gal,  but at 66 already has her hands full trying
to keep order at the hospital, hi!  She is more than willing
to help (already has done a bit of a mod inside the RX-340
for me),  but it is a chore for both of us.  And, I am older than
that,  hi!

With large enough parts and wires,  I can do it,  if I can see
them!
