Someone posted that they obtained a Kaypro 2x but not the keyboard cable for it. Jim Hart posted "I believe you can use a regular handset cable from a corded telephone".

I suggest caution.

David K, who bought the Kaypro 2X posts later  Jun 5:

I found [a phone corde]
with 4 wires and WOW - it works.  So thank you for the advice!
