Just picked up this neat collection of computer accessories and electronic bits which were literally destined for the recycling bin. Going through this stuff I feel like I took a trip back to 1978. Also everything smells old with the pleasant musk of basement mold.
A wealth of knowledge here along with various electronic components for lab use. Heathkit offered a number of electronics related educational courses. These included a final exam which you could mail-in and with a passing grade would receive a certificate.
These were sold by Radio Shack as kits for makers of the day.

ASCII Keyboard Encoder Project Board - Radio Shack Part No. 277-177
I even managed to find the manual listing the parts needed to fully assemble this.

A true time capsule.
I believe “Apple” users (it was only named the Apple 1 retrospectively) were expected to use a keyboard module quite like this. You only got an assembled motherboard from them. Quite the time to be a hobbyist! And here it is, in your hands today.

Thanks. The Motorola MEK6800D2 is not just a keyboard but an entire microcomputer yet to be assembled! My favorite piece of the collection.
