I was wrong

I can't write.

I can only read good floppies,

If I try to write or format the machine bombs.

I checked the WRTIE(wr) line from internal floppy pin 18 to the UH7 is good, also the Write(wr+) line from SWIM to UH7 is also 000 good.

I also checked the D lines from SWIM to UE10 they are all 000 good too.
