Bram - I'm forwarding our last two emails to the BB discussion group
so that everyone can join in the fun! Although your emphasis was in
quadruple formulation machines, I think this is close enough to the
5-tuple formulation to be interesting AND the overall form of your
web pages is valuable as a guide.
I understand about not looking at things for decades. Some people
contribute for a while and move onto other things, some people take
long breaks (e.g., Shawn and I), and some people continue onward
steadily. I'm revisited after retirement (although I had started
back before).
Thanks for any and all efforts to restore your website! I'm glad the
pages were still there...

Hi Terry,
Hey, that's great that you and Shawn are looking at this! To be
frank, the last time I looked at these was almost 20 years ago :P
... but I'm still very interested in these!
Given how old the website is, I'm not sure there is anything
useful for you there, but I just repaired some links so you can
start looking around to see what we have. We were mainly
interested in the quadruple formulation of Turing machines
(following Boolos and Jeffrey), and believe we found a few records
at the time. Are you at all interested in the quadruple
formulation machines?
I'll continue fixing some links .... :P
Bram

Subject: [EXTERNAL] Busy Beaver WWW site...
Hello Dr. van Heuveln,
My name is Terry Ligocki. My son, Shawn, and I have been
investigating BB/TM problems for about 20 year (off and on). At
the moment, there are several efforts to organize, curate, etc.
results and research into BB/TM problems.
There is a WWW site
bbchallenge.org much like the one you
were/are(?) associated with,
https://homepages.hass.rpi.edu/heuveb/Research/BB/index.html, and
a Google discussion group,
https://groups.google.com/g/busy-beaver-discuss, started by Shawn.
It looks like on the RPI BB there is the index page and most
(all?) of the links are broken. Are the webpages that are missing
still available somewhere in some form? The people working on the
"
bbchallenge.org" site could really benefit from the information
(and layout/functionality) of the RPI site when it was up and
running. I remember it as a very nice site!
I hope this email reaches you and you are doing well...
Terry J. (Ligocki,
tjli...@gmail.com)
P.S. I've just retired and one of my projects is research into
BB/TM problems AND helping create support for other people (in the
present and future) to more quickly locate information and
resources for further investigations...
