This is a long shot, but can someone point me to a reasonably priced
source for KW-104S 7 segment incandescent displays? I need 8 of them and
a decimal point display as well.
tnx!

So you just need the filament type 7 segs not that entire assembly, correct?
I know I have that type of 7 seg at home. Just don't recall how many and what
size they are but I'll be home in a little over an hour and I'll take a peak.

Awesome Jay, thanks!
Here's what the display assembly looks like
http://www.geneb.org/images/7seg-disp1.jpg
http://www.geneb.org/images/7seg-disp2.jpg
http://www.geneb.org/images/7seg-disp3.jpg
The way it's wired requires 9 7seg to bcd chips.
It appears they way they built it was to glue in the pcb, then mount all
the displays and then finally the 64 pin connector. I'd like to be able
to use a single Maxim 7 segment driver chip with them, but I suspect it
would take a week of work just to recover the parts from the board. :)
The displays are about .300" high.

Bad news, I looked everywhere but can't find them. I'll keep looking.

-Gene,
I have the following KW-104S, KW-104S-CL-TB, KW-104SDP-TB, KW-104S-AL I
use them in my NAV head
CP-1252/ASN-128 http://phoenixcomm.wordpress.com/projects/nav-cdu/ The
104 series runs on 4vdc and 15ma (max) any more and you pop them!! make
sure that when you drive them to use a current limiting resistor in each
segment.. also I was driving them with 74LS family but I lost some of
them as TTL has a 5v rail.
they have a .300" character height, x .155(7digit) .200(alpha)... You
used to be able to find them on ebay.. I was lucky and I scored 3 CDU's
the lamps are also called PinLite and they are manufactured by Wamco
Lighting 714-545-5560..
Basicly Gene they are harder to find then hens teeth..
Good Luck,
Cris H.

They're not hard to find, they're hard to *buy*. Best price I've seen is
$110 *each*. I've got a full set of working displays that I can use by
essentially duplicating the circuit that the VHF radio uses to drive them
(9 CD4511B bcd to 7seg decoders) but it would be nice if I could just
reconstruct the assembly and use a single Maxim 7 segment driver. It
would keep the board cost down. (WAAAY down - 9 16 pin chips eat a ton of
real estate)

you should look at the MAX6955 (I2C) or MAX6954 (SPI) plus they can
also take care of your keyboard as well. I have played with them.. (you
can get them as samples from maxim) the programing is a pain.. there are
a boat load of config registers.. but there is a white paper.. and a on
line config builder to take the pain away.
I was driving them from an arduino.. for my NAV head.. and talk about
the wire LOL. 4 of the Alphas (16 seg) and 13 more Numeric (7 segs) =
155 segments + 17 commons or about 172 wires what a mess.. and no room.
The box was originally used in a sim and had all the pins coming out
the rear of the unit.
right now Im using a ps2 keyboard encoder (a old keyboard gave up its
guts) it was easier, and it got there first (I hate re-inventing the
wheel), plus its almost a no brainer..
