Dad had this kept for a very long time under his inventory ,he wasn't aware because he is really a very bad manager of things he buys ,in the lab his area is very very badly messed up.
Then oneday while looking out for some Mosfets or power transistors perhaps he found out this pack! and told me about it.
I would guess those are much, much older than 10 years, by judging the cardboard box.
May be but I think at times dad tends to show extraordinary and surprisingly awkward memory mapping when he can spell when a electronic part was bought accurately but isn't able to remember where he kept it
You young whippersnappers. I've got microprocessors that are over 30years old (including an Intel 8089. Intel 8089 - Wikipedia ) Shucks; I've got an 1988-era IBM PC/AT clone that I'm pretty sure still works (and it has "historical significance", in its minor sort of way.)
(not counting the things that I got that were old when I got them, like the WW panels full of 4000A CMOS chips.)
(The sad part is how few of the parts got used for anything useful. Chasing the professional/personal/internet computer landscape sure cuts down on the time you have to play with more primitive configurations.)
They are all the same value that's certain, but what are they? (1 ohm and 10m the least useful unless designing a crystal oscillator circuit or sense circuit)
Back then dad used to mostly make cut out circuits to be fitted inside the alternators however a lot of other stuff like rectifiers etc too but I wasn't that involved in those other stuffs.
