Flippy Mod-Panasonic JU-475 AKJ

Post by airnocker » Mon Aug 21, 2017 6:51 am

I'm happy to report my flippy mod was a success. I searched the forum for any picture insights for adding the by-pass circuit to this drive but only found a dead reference in the forum for a flippy mod. The YouTube vid was extremely helpful, however.

So I thought I would post how I implemented the two 1K resistors and the 2N2222 switching transistor to the Panasonic floppy controller board along with some other reference photos.

It appears there is a limit of three photos per post so this next photo will be in a following post.
