Info Sought: Bi-color read/write LED for Disk II

[buggie@pegasus.unm.edu (stephen e buggie)]

I am building "Super Disk II" ----   a Disk II loaded with all hackable 
features.

Someone wrote that instructions appear in a book, "Understanding the 
Apple II" (approximate title), in how to install a two-color LED to 
identify read vs. write fuinctions.

I already have a bi-color LED on my AE 3.5" drive, and it looks great.,


Ifd anyone can find this chapter, could you photocopy it to me, snail mail?

I understand that it works with an IC soldered toi the Disk II analog board.


I( hope to brag/show off "Super Disk II" at KansasFest this July; reades 
who attend will get to see it!   (Autograph signing will be available.....)

BTW, its other features so far are:

DB-19 round cable 
Front-panel write protect override switch (normal/always write/
                                           always protect)
Front-panel vernier speed-control knob
