What logic and digital chips to get ?

bd139:
You can build anything with 74LS00's and they're dirt cheap on Tayda (think they are hitachi).

I should note, I collect/repair/restore "vintage" computers.  To me, "vintage" is 1970 to 1981.  So I do "hoard" chips and other components from that time period.  Gathering lots of TTL logic is probably not necessary for people without that or similar interests.

schmitt trigger:
Likewise here, but my hobby is related to glass electronics ( vacuum and gas filled tubes).

Since these are already in short supply and some devices are essentially non existent, the temptation is VERY STRONG to hoard some. I have to think really hard whether it is actually feasible that I will use them in a reasonable timeframe.

But if you are contemplating LSI ICs, please follow the recommendations above, before it’s too late and you get “The Disease.”

YMMV, but an argument for keeping a reasonable stock of parts other than for repairs is that you can throw together prototypes on a whim. I am kind of that way...I'll decide to try some circuit on a lark and it can kill the muse if I don't have the right part on hand and have to wait for an order. Definitely don't have a garageful of stuff you'll never use though! Small quantities....

wilfred:
If you have to buy one part you may as well buy all of them. I always struggle to get to the free postage threshhold so that's the way to build a stockpile of parts. Buy spares of what you are using.

You're not going to have everything you need and you're not going to use everything you buy. That has to be a fundamental law of the universe.
