Hi Dave,

Yes, I know of the elusive E-Mu schematics . I fortunately have a complete
archive of every module we ever built and/or shipped including Front Panel
Layout and calibration details. Unfortunately it is Blue-Print and photo
copy material. A real pain to convert to scanned docs.

However, I am willing to redraw interesting circuits of the modules folks
need to peruse if I have the time.

Any idea where I can find SSM devices such as ssm2020, 2010, 2030, 2040,
etc. ?

Some of the later E-Mu submodules are using the SSM chips we designed.

I do have early schematics of modules that were using discrete VCA /
Transistor designs. Just more work to build but as I said I have the entire
archive still in my file cabinet.

Regards,

Terry
