7406 and Floppy Fix

Post by PeckPeekPoke »

From what I've attempted to glean from photos, here is a sketch.
Could someone verify this?

Besides the 10kSil added to the WD1772, when adding resistors to fix floppy performance; on the 7406, there should be five 100k resistors wired from the pins coloured red in the drawing, (2,4,6,8,10) all terminating together at pin14.
Is this the correct ? :?

Yep sounds correct. But 1k not 100k.

Just because a lot of people agree on something, doesn't make it a fact. ~exxos ~
People should find solutions to problems, not find problems with solutions.
