@Klyball, I just saw Leo Binkowski’s YouTube video and he showed both sides of his floppy drive controller board. I could see the wire and resistor added, exactly the same as @snuci’s board. If he posts a video of his board working with his NABU floppy drive, then we’ll know for certain that...

@Klyball, are you duplicating @snuci’s board exactly and then adding the jumper wire and cutting the trace just like @snuci’s board? Or will you mod the traces to incorporate the fixes applied to @snuci’s board?

@Klyball, what tool did you use to create these layers?

Wow! you are one of the 0.1% of people who not only post pictures, but made the extra effort to desolder the chips from the board so we can see all the traces! I'd hate to ask this but could you provide the dimensions of the boards?

Thank you @snuci for creating a new post with the pictures. As requested, here is the link to the FD schematic in the T1100 technical guide (see pages 98-159) https://vintagecomputer.ca/files/Nabu/Nabu-1100-Technical-Guide.pdf The schematic in the Technical Guide is for the AFC1100 Floppy Disk...

I wrote Prof Stachniak at York University’s NABU Network (YUNN) asking whether they would host some of the original NABU programs they acquired for the Museum. Here is his reply: “Thanks your kind words regarding my presentation. I'm aware of the "resurgence of interest in the NABU network" --...

Sorry if this is a bit off topic, but @snuci your picture of the FD controller board got my attention. Can you post pictures of it here? The NABU technical manual includes a schematic of the FD controller board but it shows a circuit using Western Digital’s FD1793 and a phase lock loop using...
