One of the more interesting thing's, I have found the SC/MP II involved in.
I wonder why National Semiconductor's database can't be found on TIs site?
Thank whomever had the foresight to archive old document's, and make them available on the internet, as my original ringbinder was pitched long ago.

It's possible that as National was compressing itself into the company that TI ultimately bought they made a decision to jettison those products who were ultimately declared EOL before they even got there.
For example I have scads of TI branded TTL chips here. And a lot of them are not even listed inside the the TI site. Fortunately I do have the company data books for early on still here.....
What I am trying to find however is someone who can provide the entire line in DIP form for them....

It's a shame these companies can't keep an archive of their products, these chip's are still here and usable, because the company can't spare a small amount space for info for product's they invented, at least make them public.

I have a lot of old data sheets in scanned paper, PDF, and paper form I would be willing to share if anyone is interested. Ask, and if I have you will receive.

Thank you for your foresight. However my problem is more of finding the actual parts. So far I was given contact information for someone. I wrote to him, and, ah, nothing happened. My site, www.gregg.levine.name lists there the current ones I am (still) looking for.

I tried your link but it kept timing out. Still have some old chips kicking around as well, although I got rid of a bunch a while back. If you let me know what you are looking for I will let you know if I have them.
Hmm...the HTML at www.gregg.levine.name want's to display a frame from drwhotimelord.dnsalias.net which does not resolve. It has no IP address according to whois.

Hello!
I need to speak to the manager of the location, :chip: it worked for me.
Okay here's what the page is gronking about:
I am looking for the following TTL logic devices:
SN7423 Dual 4 Input NOR gate With Strobe One Gate Expandable
SN7425 Dual 4 Input NOR gate With Strobe
SN7450 Dual 2-Wide 2-Input And-OR-Invert Gates (One Gate Expandable)
SN7452 Expandable 4-Wide And-OR Gates
SN7453 Expandable 4-Wide And-OR-Invert Gates
SN7460 Dual 4-Input Expanders
SN7461 Triple 3-Input Expanders
SN7462 4-Wide And-OR Expanders
Also these Flip-Flops
SN7470 AND-Gated J-K Positive Edge Triggered
SN7472 AND-Gated J-K Positive Edge Triggered
I know that the fellow who ran Mr. Benny's household eventually went into the electronics business, that is, making up replacement parts. How? He bought the masks, and the rights to continue to make them. They're available from several vendors I believe. But at the moment not in my (current) quantities. That first one is something of a unicorn, it was still made in 1987, but only in the SN5423 configuration, and then hiding behind an almost incomprehensible Mil-Spec number. And if someone were to ask TI for the second one's datasheet, it would include the first.
Although I'll get howled at, I'll even accept ones you do have and definitely do not need.
Oh and my first batch of numbers who do that came from a Jameco grab bag assortment. I even bought a pair from them not too long ago hoping lightning would strike again. It missed.

What browser are you using to view my site? It shows up perfectly on Chrome. Rudely on IE, and unhappily on Mozilla Firefox. The first site, the registered domain name, is an alias for the second who uses DyDNS for that purpose. FYI look here: dyn.com/dns/
Strange? How did your robot get to a big business for Shopton NY, Erco? Oh he's getting a new power source installed as well.
Hello!
If kwinn does not have the really important ones, which are the expandables, I'll try that site. Thanks!
I'm confused, Your looking for genuine NS manufactured?
No TI branded. NS, and TI, and FSC tended to follow each other in the TTL race. Last to follow it was Signetics, they became Phillips, and eventually NXP and now something else. I'll accept NTE since they are almost close. I have here an NTE74LS629 who behaves within 89% of specs for the TI design.
We're now moving further along from the Z80 a processor who shares one thing with the R6502, both are easy to use and since this is a part of that, easy to program.
Oddly enough I have a book here for building something around the I8080, too complicated and the different power supplies needed happened to be all of the problems for not building such a system. And one on the I8088. Same as the I8080, but one power supply now.
Now we are discussing the glue logic the processors use to work with us.

Basically nothing but an frame that displays "http://drwhotimelord.dnsalias.net" or provides a link to go there if your browser does not support frames.
Group the site is at home.
In fact I've even reset everything imaginable here for it.
In fact go here, whois.domaintools.com/ I gave it the location we are griping about and in fact your browser should show something appropriate. Oh and do the same for other site we are complaining about.
What we need is someone reading this on the ISS and to try it.......

They have a few.

IE does not work.

Strange..... Last time I checked.... It must be generated by the bitpushers behind the DyDNS gang. Don't blame me, I didn't order it.
And I'm blaming a guy named Murphy and one named Finagle. They were originally assigned to the sewage detail.
Does your browser include a debugger? Run it through it. The actual site is indeed the one its trying to send you to.

Same here. And same here.
Strange. I suspect something is stranger then usual where you are. Time to give the Internet a good kick I think.
:nerd:

No everyone else is having problems with your web site, not just me.
The page delivered by http://www.gregg.levine.name is this: Basically nothing but an frame that displays "http://drwhotimelord.dnsalias.net" or provides a link to go there if your browser does not support frames.
BUT, http://drwhotimelord.dnsalias.net does not resolve.
All very odd.

dnsalias.net resolves to 204.13.248.119 and indeed there is a web page there.
drwhotimelord.dnsalias.net does not resolve so we can get nothing from there.
$ wget drwhotimelord.dnsalias.net
The search at whois.domaintools.com/ did not help any.
like www.xxx.net or mail.xxx.net
There are 2 ways to handle this in the DNS system.
One way is to specify a different IP for the name.
One way is to send all requests to the same IP and let the webserver sort it out.
In that case you have to specify something like *.xxx.net in the DNS.
Then you can, without changing DNS records simply add a new website by telling your server to bind to the new host header.
in case of drwhotimelord.dnsalias.net not getting resolved I think they did something wrong there.
maybe drwhotimelord needs to be spelled differently?
dnsalias.net sounds like someone knowing how to do DNS entries, but you never know.
Enjoy!
