so i found a load of old stuff !PICS!

[birt]

and that allways raises questions...
so i'll make a list of what i found and ask some things when i get to it.

if you see something usefull, please do tell me!



ic's:

ITT 7400
philips NE555N
TLC27 1CP
motorola MC851P
F7738          (x4)
ITT N66 SAA1025
770939X SGS 17240
NS MM504 6945       (x2)
NS MM504 111         (x3)
2206CP
NS 7028
TDA 2108
C 3106             (x2)
C 3106A
D 3601
LM358N      (x2)
TMS 4044-30JL P7810     (x2)
NS 330 MM5314N
GIM A78131 7521K     (x4)
74LS125DC OR 7831
SGS 7419
7524
SGS 7304    (x2)
7641
SN74221N
AY-3-1015D 8012  (this one is huge! 20 pins on each side)
NS 70012    (x5)
ICL 8001 C 7403


then there is a huge load of resistors.
lots of caps caps from 50 to 1000pf

about 100 5K trimpots
9 1k trimpots
more than 50 trimpots with values between 10k and 100k

caps, fuse holders, switches, power resistors, leds.

8 bridge rectifiers

a box that sais LDR, please tell me more because i don't really know what those are. there are black boxes with 4 leads that say:  NSL PL 1033-1
there are glass-like colored discs with 2 leads and there are tiny thin gold sprkle rectangles with 2 leads.

SHARP S202DS4  (x3)
don't know what it are, they have four leads and can be connected to a heat sink. they have +, - and a wave sign like rectifiers but i don't think it are rectifiers

transistors:

BC549    (x9)
BC547    (x15)
2N1613  (x22)
BSY53   (x10)



diodes:
NEC 1S119  (x4)
SCIN 5199 6902  (x8)



shoot!  :lol:

[puretube]

ask 75$ for the TDA2108...

[birt]

ask 75$ for the TDA2108...

:shock:

are you serious? why are they so expensive?

[puretube]

rarer than SAD512 or SAD1024... I`d try $99...

[object88]

Apparently they're 2048 stage BBDs, perhaps compatible with the 3008?  Scouring the web dug up no datasheet and a few places selling them for ~12 pounds or 30 euros... but I have no idea if they actually had them in stock.

[Mark Hammer]

It's finally happened.

Antique Semiconductors Roadshow!!!!   :lol:  :lol:

Bring your old chips found in the darkest recesses of your parts bins, and have experts assess their current market value!

"Ah, well what we have here is an old Mostek top octave divider!  Where do you find it?"

"Well, my father had a hobby organ he was working on during his retirement.  He never finished it, and shoved all the parts in a box.  We were cleaning up the garage for him, and stumbled across it."

"I would estimate this chip as having a market value between $60 and $100."

"You're joking!!  That little chunk of black plastic?"

"Yes.  Not only that, but the chips labelled SAD512 are also worth a similar amount to the right buyer.  Total estimated value of your little pile of parts....roughly $200[/b]  So, what do you think?"

"I'm astounded, really.  I mean, you wouldn't think to look at these things.  They all look the same, really, quite like little bugs."

[loscha]

Do you want cash (paypal?) or swaps?

Hmm, I am mistaken. That AY isn't one of the synth range of AY's, it's a UART. So, possibly isn't that much to me, but, I'll check out the list again against my databooks and the books at college and get back to you.

I can see Mark has been thinking about this for some time. Who have you got organized for the panel Mark?

[Steben]

If these would be high-cost fantastic boutique semiconductors,...
I would say tube amps are becoming very cheap ;-)

[niftydog]

here's my bash at it, no guarantees of accuracy;

ITT 7400   Quad 2-input nand gate
philips NE555N   555 timer, useful!
TLC27 1CP   programmable op amp, potentially useful
motorola MC851P   monostable multivibrator
F7738   ?
ITT N66 SAA1025   30 ch. Ultrasound receiver for TV
770939X SGS 17240   ?
NS MM504 6945   ? potentially optocoupler
NS MM504 111   ? ditto
2206CP   monolithic function generator, useful!
NS 7028   possibly static RAM
TDA 2108   2048 stage BBD!!!!!!!!!!
C 3106   These aren’t transistors are they??
C 3106A   ditto
D 3601   ditto
LM358N   vanilla op amp
TMS 4044-30JL P7810   ?
NS 330 MM5314N   digital alarm clock IC
GIM A78131 7521K   ?
74LS125DC OR 7831   quad tri-state buffer
SGS 7419   schmitt trigger inverter?
7524   8 bit DAC
SGS 7304   multiple hits, could be another 8 bit DAC
7641   op amp or 16 bit DAC, again multiple hits
SN74221N   dual monostable multivibrator
AY-3-1015D 8012   ?
NS 70012   ?
ICL 8001 C 7403   quad 2-input nand, open collector

transistors:
BC549   general purpose NPN
BC547   ditto
2N1613   NPN medium power
BSY53   NPN

[birt]

nice info!

if you know where i can sell some of that stuff ( i won't be using everything myself) let me know.


the organ is quite right, amongst other things :lol:


i have way more transistors and ic's waiting for me on that attic by the way :lol:

[Hal]

nifty - was that off the top of the head, or did you google them ?

im impressed by the NS 330 MM5314N digital alarm clock IC

:-D

[niftydog]

ah ha... trade secrets my friend.

Some where off the cuff, I know my logic gates pretty well, and some of the op amps were obvious, but others took some digging around in various resources we have here including data books, CD reference catalogues, secialist suppliers etc.

[ExpAnonColin]

The TDA isn't worth THAT much.  I can't think of any pedals that use it off the top of my head, and it's available for 8 euros here:
