• Jameco MPU Grab Bag

    From Jeff@21:1/180 to All on Wed Jul 28 15:22:48 2021
    I ordered an MPU Grab Bag from Jameco for $20, to see what was in it. Here's
    a list of the DIP components. There were 6 or 7 SMD components that I didn't bother to identify, because I'm not that into torturing myself.

    Many are in the grab bag because they're surplus or discontinued. The Programmable CRT Controller had a copyright date of 1974 on it. So if you wanted to build some kind of retro thing out of old chips...

    I also bought an LED Grab Bag ($7) that had different shapes, sizes, and
    colors of LEDs in housings that looked like they were designed for some particular purpose for which they were no longer needed. They're straight-up LEDs and were all either Red, Green, or Yellow. Most were the usual domed-cylinder LED shape, but some were rectangular cuboids. Some were mounted by themselves, some were mounted in groups. All of the leads were intact; they had never been used.

    Jeff.

    Wow. That's cool.

    I need to remember this when I order from Jameco again.
