A few comments, no flames intended-

While the schemos are indeed up there, the quality leaves a lot to be desired.
Saved as a B&W only gifs, the scans miss out on so many necessary small
printed items like parts values.

Also, for those that are not aware of this, there are several different
revs of Moog modules.
I've seen at least 3 different 911 envelope designs and 4 or 5  different
902 vca designs.
The more common earlier 901A and 901B design is not included and neither is
the 928 S/H.
(Unfortunately, I don't have these either)
The schemos on line only reflect one rev of each of these modules as well
as their calibration info.

Again, I'm not trying to make enemies, I'm just pointing out  that the
statement  "The Moog modular schemos" are online, might be a bit
misleading.

I can understand them being useful as a repair guides or as a hint to what
designs Moog used for specific modules, but for those that want to DIY Moog
modules, they leave a lot of specific, exact info up to guessing.

Trying to be tactful, yet informative... :)
