Eventually the aluminum die bond wires could corrode away, but that’s not likely to happen very fast. As far as the school giving us a junk box of parts I am sure I paid at least twice what I could of put it together myself for. Cheers, Howard Winter St.

Lord knows why the school gave us some of this stuff though or where they got there stock from. When I was searching for myself I really depended on finding a quite literal match as I really don’t know the logic behind the numbering. Yea; I’m not home right now but I was thinking the same thing quite frankly after having little luck with google I didn’t expect for as many responses so quick.

But that doesn’t stop my “good chip to keep” detector from going off. The dice themselves dm74l151n hermetically sealed with a thin layer of glass on the top surface except on the bonding pads.

I don’t think so. OK per request here are the rest. I put together the pulse generator circuit in that datasheet.

I can defiantly come up with some use for them if anyone can ID them I like having a large surplus of components Its just It seemed pointless to keep them around not knowing what they were. The sawtooth output didn’t produce any output.

I don’t think I recognize that appearance. Jinx, On Wed, 07 Sep I am really friken tired of Laplace transforms, lol.

When I get home tonight I will list the rest Justin. To fit into their part number system and those numbers it would be something like NJMJ, which doesn’t seem to be a valid part number. I doubt anything too useful will show up in these.

I have little knowledge of the Motorola variety preferred the Commodore enhanced version but I believe they were used extensively in bygone days in small micro-computers before PCs became popular http: Tuesday, September 06, 4: Probably mostly logic gates. I managed to identify about half of them and find data sheets and the other half nothing. If any of these are particularly static sensitive they probably are keeshed after 4 years of floating around in a tackle box in the trunk of a car and dozens of hands digging through them looking for specific parts in labs.

You may as well list the rest of the part numbers you have. Also I’ve seen discolouration on pins where they enter the IC body and I wonder if this is some sort of material migration or break- down at the seal. It’s Allegro anyway You shouldn’t have too much trouble finding datasheets for these.

So now I figure I want to get some projects and practical experience under my belt before I move on for a Masters and yet more calculus and theory. Hard to imagine how small memory was back then. Stuck eight of thoses ‘s on my Kim in order to get some real computting power.

Best regards, Spehro Pefhany –“it’s the network Pay no attention to the man behind the curtain! Thanks for all the speedy responses.


I don’t know how to program PLDs but I don’t think the school even had the means to do it. The school had given us tons of IC chips that we never used. Maybe it’s something else that is going on. I had one of those. There only admittance test was a 12 min timed IQ test if I recall right. Now I put this together quickly on a breadboard with approximate value components so I didn’t expect much and if I had any sawtooth output I would of considered it a success.

Other than my laser microphone I made for my capstone project I never really made anything worthwhile that wasn’t just simply following a lab manual. Microcontroller discussion list – Public. The associate degree wasn’t even accredited the BS was though that’s why I went on for the BS at the same school after the associate degree.

As it stands now it could just be a mater of putting it together with xm74ls151n exact values and keeping the leads short ect They’re supposed to be hermetically dm7ls151n but I do wonder about ingress of moisture. Blessed are the Greeks. Better than just chucking them out. If I remember rightly I had to make to with 2k x 1 I think memory chips, of which I would have needed dm74,s151n to give the same amount of storage as one of the above! Ah yes, well spotted that man.
