[Coco] CoCo 3 Keyboard

[Barry Nelson]

 After returning from the CoCo Fest, I went to install my new triad memory expansion. After a scary experience where for a while my CoCo 3 did not want to output video, I have the CoCo 3 working again, but it seems that unplugging and replugging my keyboard has caused some rows of keys to fail. Who was producing the replacement mylar keyboard sheets and do you have any?
