AR-318 & other AR series modules?

[Peter Washburn]

Hi All,

I inherited an old modular system composed of modules having the label
AR-xxx on each of them. The only reference I have found to any of them
is a schematic of the AR-318 at http://www.ultranet.com/~mute

I am in the process of rebuilding some of the components so that it will
be more stable and it would make the job much easier if I had some more
info or schematics.

It has 0-10v CV and +/-15v PSU, and most of the modules use SSM chips of
various stripes.

If anyone has any info about these machines I would be much obliged.

Many thanks,

Peter Washburn
