Ah Yes, The first thing I printed out with my Litton 1251 when I got it into
my living room in the mid 80s was a Snoopy calendar. All in punched tape.
Nice machine, wished I had kept it.
Paul Pierce has a Litton 1231 in his collection for when he gets his museum
started in PDX.
Punched tape, drum memory, console wi printer, Yum Yum...

Anybody have the text for this calendar?

New subject: Restoration Question
I have recently acquired a couple of build PC boards that are not solder
masked. There is some oxidation, ranging from minimal to mild (mild being
the not quite green, but a very hard oxide, as if the tin had reacted with
something else). Anyone got any good ideas on cleaning these? I'd like
something non-submersible, since one of the boards contains keyswitches.
I have plenty of experience cleaning unbuilt boards. Normally, I'd just
hit them with some super fine steel wool, or buff them with 20lb paper. And
I've repaired boards, but usually to get them working, not to restore their
aesthetic appeal.
I've considered using a baking soda solution and a stiff bristle brush.
This should neutralize any corrisive elements, and the baking soda might be
abrasive enough to remove the oxides without damaging the board. It would
wash off easily enough with water, and I could protect the switches during
that process.
Anyone got any ideas or standard procedures for this kind of thing?

Do not use steel wool. When used with copper or aluminum, you will almost
certainly get pitting in the future, as the wool leaves very tiny slivers
of steel embedded in the metal. Best use brass or bronze wool for copper
circuit boards.

My first question is why you want to clean them? Without refusing the
boards, you will never get back the shine that comes from a freshly
cleaned and fused circuit board. The second best thing might be to rinse
the boards in dilute muriatic acid to get at the oxide, and then brush
the board with a brass/horsehair brush. There is also something stronger
called SolderBrite that is also used to clean the tin-lead on circuit
boards after etching and before fusing. You might be able to get some by
talking nicely to a nearby circuit board house.

Do you mean something like this BASIC program, which
prints
the Snoopy image. Sometimes it was run followed by a run
of a calendar program.
I see. I thought it was a separate image for each month.
I found this 1981 Snoopy calendar, too, though I can't make the image
out. <http://www.textfiles.com/art/snoopy.untab>

There may have been a program that did this.
Hundreds of calendar programs were written (and a few of
them even handled leap years, and a very few of them handled
leap years correctly).

It's just a <wide> ascii file with a calander for 1981 stuck on the end.
Easily viewed with a fixed font.

I think that there were hundreds of snoopy pictures floating around.
You should be able to find many of them on the internet.
Some were much better than others.
