Howdy, i have many random ICs, and am looking for ideas...

Greetings DIYers!

I have been lurking about these parts for quite some time now, and finally decided to actually register. I consider myself a beginner, but i am starting to understand small bits and pieces more often as i go along now. However, i am also amassing questions at an alarming rate.

Basically, i am building on a 80-90% salvage basis, only buying what i have to, i.e. footswitches, stripboard, and odd cap/resistor values. Luckily i have an interesting small pile of junk electronics to strip.

I have built a few different things so far, in order: a Marshall 18w tube amp, a Fuzzrite, a Muffmaster, a BYOC Tri-boost, an OD-250, the Crunch-it!, Highway 89, and about half of an Orange Squeezer, that i seem to need to get new 2N4547s for.

Now i am looking into the land of synths, noisemakers, theremins, and i intend to do at least one of the R.O.G. style amp sims, but still open to just about anything interesting that makes a good noise.

I have a lot of questions, but i will start with this inquiry. Among my pile of salvaged electronic bits, i have the following ICs. Is there anything there i can use for an interesting DIY project? I have been gathering and continue to gather their data sheets, but ideas for possible projects are welcome. There are some i know what they are(lm1458, rc4558, mn3007, mn3101) but a bunch that i don't know, such as:

(1) 14-2054-01 274 631 1 <- that is all it says. what the heck is it?

(1) MC1328P (Motorola)

(1) 7650 SN7439AN (Texas Instruments)

(1) MC14007UBCP

(1) NE5560N

(1) NE5532P

(1) 221-129 A 014 M8141

(1) 2059-01 7620 (Motorola)

(3) 5218A 2511 (Mitsubishi?)

(1) 2008-01 7636 (Motorola)

(1) 2059-01 7620 (Motorola)

(1) LB1639 2B9

(1) LM393N

(2) 4N35 8130

In addition, i have some older computers here that have tons of socketed ICs with numbers like AP8127 TMS4116-25NL, P8428 DM74LS175N, M5K4164NP-20, TMS4164-15NL, M5K4164ANP, etc, etc...

Any input or project ideas would be very helpful. Thanks!

MC1328p 80/100MHz video processor ( video player/recorder )
SN7439AN dual 4 bit decade and binary counter
MC14007UBCP dual complimentary pair plus Invertor - three N channel and three P channel enhancement mode devices
for use as invertors/pulse shapers/linear amplifiers/high input impedance amplifier
NE5560N - Switched mode power supply control unit
NE5532P - dual opamp, decent quality and standard pinout use for any boost/od needing a dual opamp
LM393N - low power dual voltage comparator
2059-01-7620 could be VCXO frame clock freq translator

Can't seem to find much on the rest .... I'm sure others will chip in

The 4n35 its an opto-transistor

LB1639 2B9 - Low-Saturation Bidirectional Motor Drive for Low-Voltage Applications

Thanks guys.

So the real question is, aside from the dual op amps, what, if anything, can i build with this stuff?

Is there anything that uses old PC RAM? A Looper or something? Can RAM be misused to make noise?

What would i do with the video chips?

I am guessing they will probably be headed back into the pile for now, eh?

Thanks!

(3) 5218A 2511 (Mitsubishi?)  Most likely more known as M5218, Dual opamp.
(2) 4N35 8130  Optocoupler
