I have the same issue. I need three obsolete chips from National Semi, DM
8131, DM 8836 and DM 8837. I have scoured the internet with no luck.
I do have a board with these chips in it, I may have to resort to
desoldering them. I just hate doing that, it tends to ruin the source board.
For small amounts I use Jameco Electronics...
Where does one go to find the not-very-common TTL? e.g., the 7497
rate multiplier; the 74199 8-bit register, etc. TI had some pretty
estoteric circuits also--74LS362, 74LS444, 74S485, 74S481...

At the risk of sounding like a broken record, MC Howard in Austin,
Texas has been my source for everything from 74-series chips to 64-pin
wirewrap sockets to RAM for my HP-9000. I basically populated my
SBC6120 off their shelves, and the homebrew 6809 project I'm working on
was provisioned there too.
The prices on their website are insane, but I've never heard of them
actually charging what's listed. Call the toll-free number or email
them and get a quote. They ship internationally.

Not affiliated, satisfied customer for over 10 years, mumble mumble
etc. I know a couple of other listfolk have dealt with them too.

Interesting. If I tripped over that website on my own, I wouldn't have
the impression that it was worth my while to deal with them. Literally
everything brings up a page stating "...Coming Soon".
Still, your recommendation carries weight and I'll file the link for
future reference.

I know. The guy who built that site graduated and moved on 10 or 11
years ago, and I'm not sure it's been maintained since.
I forgot to mention their eBay store: mchowardelectronics
That's a much better example of their wares.
