Thanks Randall, as always!
On the subject of the proper wires to use inside the Dizzie. What is it OK
to use - I mean can I go to Radio Shack and buy the skinniest stuff they
have? I seem to remember that TRF did not have the pre-made ones when I
called. That was several years ago mind you - back when I had TS78910.
You are correct about the archives - I still owe Mark for my pledge so maybe
he will be able to update the software. I might be willing to do it on my
Domain as well.. Hmmm.
