Wow, thanks Dave! Who said old farts can't learn new tricks?
I was never aware of the A, B, C, D, & E lettering scheme to designate the size of the shell. I am guilty of belonging to the camp followers that just changed the number pins on the DB-25 to DB-9.
I patiently await my 50 lashes with what I hope is a very wet noodle. :-)
Thanks again Dave. It is great to belong to such a group that allows me to learn new things even at my age.
