Introduction: Second Life of MFM Hard Drives - Iambic Telegraph Key

Do you remember a MFM hard drives? Not too fast, but very large - 20 Mb in the 5 inch rack, it was a something special! Times gone and those beautiful drives decided to rest in peace. In peace? No way!

One note - if you don't know wha-da-heck is Iambic Key, visit Wiki: As for me, this key is my way to communicate World. Our Old Good World.

Step 1: Extracting Heads From Dead Drives

There are best-of-the-best bearings inside. Because it is.

Step 2: Cut Off Fag End

Step 3: Breadboarding and Making the Plastic Base.

Breadboarding - making something using wife's bread board In my case board was slightly rustic.

Step 4: Assembling and Assembled Views


Step 5: Comunicating Using New Keyer

What are the pins on the front from? Is the speed adjustable? The two wire on top, what are the connected to on the top and bottom?

Cool.  I suggest typing out a message in Morse code for us to decode!
