A few vintage things

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.

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. :D

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

Maybe one of these days I will stumble on an Apple I ;)

I just unsealed the last box (time capsule) to discover this Heathkit ET-3100 Electronic Design Experimenter.

Here is one of these fully completed:

I recently spotted something neat on eBay I figured I would share. It is the completed keyboard encoder board, the very same as mine. It is fitted into a nice metal framed housing and has the Heep test module installed which functions as an led display to test the keyboard ouput in the absense of a system that accepts ASCII codes.

That Tandy board reminds me allot of the stackpole switches that came attached to the original Atari 800. The keycaps look like very similar construction too, with thick doubleshot plastic.
