Here are mine:
WF VQC10... LED display with integrated ADC...
Very old (1982!) WF VQB32 (unused of course) and a MQC10:

I've always liked Minitrons and Pinlites, too. (Both are incandescent, pre-LED.)

Some early "claw"-style LED displays:

You might find this page of interest:

I have some different types of displays; mainly LED and nixie but also a Panaplex still attached to a panel meter board, a Pinlite style figure-8 display and some nice HP BCD hexadecimal LED display modules (and a clock I made from some).
Pics to follow... |

You guys got me so interested in displays that I got my first Nixie display today with 5 tubes on a working board.
I'll post my small collection of display screens & display chips after the Nixies arrive.

| I'll see if I can dig up my LED display (Similar to Frassl's MCQ10) on Blue PCB with silicon die attached to PCB , without blob or cover |

| That "Hewlett-Packard HDSP-0962 " is the sexiest display I have seen for a while, sheer beauty! I would kill for that IC. |

Really?
Is this OK for you?

There are a few people I'd like killing at the moment; namely the bastards who just burgled my house. |

So if I kill them, you'll give me a few ICs?
I'm collecting some ICs and DIPs and CPUs with windows and visible silicon- That small display would be very nice in my frame |

Dohh 
Do they touch to your collection?

Thankfully no; they only took things that can be easily replaced (£4000+ worth)
I have 2 full boards like the one in the picture each with 16x displays (these have HP stamped on them with part number "4N54 TXV (7395)" but searches reveal the datasheets from TI and 'Micropac') and associated mux / driver ICs and a flexible printed ribbon.
http://www.micropac.com/pdf/products/67023.pdf
Shown here running on my old-skool digital clock:
http://www.nitrate.plus.com/Files/Pics/clock_digits.JPG
They are pin-compatible with HP's 5082-7300 (http://web.mit.edu/6.s28/www/datasheets/HP_led_display.pdf) which are the other displays on the clock show below, used to compare between them (here you can also see the PXO oscillator that I mentioned in another thread).
http://www.nitrate.plus.com/Files/Pics/clockfull.JPG
Please note that they are brighter than they appear compared to the ones with the red casing; which helps to make those displays more visible because they are diffused. Please note that the 4N54 has had the legs extended because it was soldered and clipped.
Both types are very nice displays because they accept 4-bit (1 nibble?) BCD input. The 5082-7300 are digits 0-9 with decimal point and the 4N54 is 0-F hexadecimal. Both have chip enable (for multiplexing) and blanking function.
The 4N54 are for sale:
1x desoldered + shipped UK = £2.00, EU = £2.50, rest of world = £3.00
Full PCB (2 available) = £25 ea. Please ask about shipping. |

Here is the small selection of display items I have so far.
I wasn't originally collecting these, but I received these in lots of chips or boards that I've purchased and now I've come to like them as much as other chips.... 
Pictured above is one HP, two MAN and three KW pinlites.
A FUTABA (Japan) display from my old 1980's Sharp printing calculator. the numerals light up a nice blue and I would like to be able to have it light up again. It's still attached to the circuit board with CPU on the backside.
A large heavy display screen from a vintage Burroughs mainframe with it's own circuit board attached behind. The glass front is very thick.
View of the Burroughs display PCB with Fairchild? chips dated "7218". The power connector is still attached, so maybe this baby will still light up with the right power supply.
(I got the power supply board and many other 1970's boards from this Burroughs computer. Anyone from the "brain gallery" have suggestions on this?)
A nice little display chip on a small circuit board that I unplugged from the AT&T Mainframe panel below. No ID visible on it. It's a 20 gold pin ceramic chip encased in a plastic package. The 14-lead connector is attached to the circuit board, so this can possibly be made to light up also.
My first Burroughs Nixie tubes that I just received. They work, but I have no power supply to light them up, yet.
Another winter project  |
