Vintage TI 74xx series logic

[@rt]

Hi Guys

I have a few more of these Texas Instruments logic chips on the way. The next one is a dual flip flop.
I was hoping to test them in in some kind of jig without soldering. They are a smaller package than I thought.

Does anyone have any idea, or even pics, of the type of sockets that would have been used to mount these?
Any more information? and do these markings suggest the 20th, and 21st week of 1973?
If these are date codes, the flip flop in the same kind of package is the 26th week of 1969, so the package must have existed for some time.
Thanks

They would have been cut out of the carriers with pin lengths of perhaps 3/16" and surface mounted. Same pin spacing and body size as a SOIC.

Those are a bit odd. That type of package would normally be used for Mil/Aero kind of stuff, but in that case in extended temperature as SN54xx, not SN74xx.
Interesting, they would have been expensive back then.

According to their price list for 1966, then such packages were by default. If you wanted a plastic DIP plug-in package, then it needed to be specified ("Add the suffix "P" to the type number to order Series 74P in the plug-in package").

Cool doc! So they do have socketed boards for them then such as SN006A.
I take it for manufacturing these wouldn’t be used?

Why am I even doing this? It started with vintage ceramic CPUs that I would actually use in old computers,
and I guess I got carried away.

Chip collection is infectious.

By one of us, you mean poor? Yeah that already happened
Part of me is already trying to restrain the other part from looking at vintage wafers.

Looks like I do have a problem
Shame this one came in plastic bubblewrap.
