[GreenKeys] Circuit board of unknown origin...

[Mark Hall]

Hello again Greenkeyers!

I'm posting this in the hopes of identifying this thing. It's attached to a
model
19 I will move to Oklahoma real soon. While it doesn't look like it's "made
in
Skokie" it is neatly done, installed in a workmanlike manner and appears
well
thought out. It could be easily removed if needs be, without altering the
model
19 or its table wiring to any serious degree. Connections to the table are
made
via a separate terminal strip behind the table's REC-33(?) supply, and from
the
board itself by a length of multi-conductor cable terminated in what
appears to
be a 4 conductor Cinch-Jones connector.

Attachments are jpg format. Open to "full screen"  for best view.

A11.jpg shows the back of the table viewed from left corner facing back of
table.
This shows the REC-33(?), a terminal strip behind it with the connections
from the
board and table, and the board in question in the far corner, with the
connector
cable under it. Above the board a wiring diagram for the table is pasted.
Everything
in the diagram and in pics of the machine seem to correspond and appear
correct
for the machine and table.

A12.jpg- the board in question. Neatly mounted and "plumbed in". The table
wiring
diagram appears above it. Discrete components and bread board construction,
with
what appears to be two diodes and a relay(?) on the metal mount board
underneath
the bread board. The Cinch-Jones connector appears, and the connector cord
is
neatly coiled underneath the board.

In my earlier post about Dave Tumey and Heavy Metal RTTY, I mentioned this
19
has a pedigree for RTTY. Well, here it is:

A3.jpg shows the Bell Teletypewriter Service plate attached to the front of
the machine,
with the number window displaying a call sign- "W8UXV". When I saw this, I
felt a great
sense of respect- I would get to be the ham who returned this machine to
the airwaves.
What an honor. A tradition continues!

A5.jpg was a real treat. Inside a well-aged cookie tin, a partial roll of
perforator tape resides.
Along with two CQ tapes, a QSO card tape, and a mystery tape. Across the
top of the photo
there is an unrolled tape marked in red ink "Great Speckled Bird". Printing
that one out will be
a real surprise! I know there was a RTTY image called "Great Speckled Bird"
but I don't remember
what it looked like.

Any help with identifying this board and what it might be used for would be
welcomed. Having
this machine come my way and be in my care is something I'm very happy that
came to pass.
Being able to use it and develop my "chops" for RTTY Roundup's "Heavy
Metal"?

My history is being made, and this 19's history is being remade at the same
time. How great is that?!

Respectfully 73, y'all...

Mark
