    My wife asked me to fix the coffee grinder - to my surprise, there was a through-hole chip (CD4541 BE). I felt like I found a living dinosaur!

    The grinder blade was worn smooth so it became landfill. She replaced it with the exact same model - I assume it has the same chip.

    Even if the new board uses SMT, if the design is identical, you could still use the board as a spare?

    You never know until you take it apart... but don't let the boss see you do it.

    Many manufactures still make pDIPs... they are usually cheaper - if you can afford the space.

    Yeah, I wouldn't say through-hole is even close to "rare" yet, at least in the things I tear apart.

    Sometimes you get lucky.:p My sister sent me a multi-motor chair vibrator and what do I find but 1970's technology!:cool: So I fixed it to use the remaining motors and another motor died in about 6 weeks.:mad:

    Lucky doesn't always last very long.:(
