[sdiy] Looking for infos / Roland System 100m

Re System 100M

I played around with the delay/phaser module back in 1980, 
and  really enjoyed it, though don't recall the details. I 
do have the original advertising material for the system at 
home somewhere.

As for sockets, mine are still good after 20 odd years. Some 
plugs don't fit, but that is usually the fault of the plug - 
some are poorly built, with the insulated ring larger than 
it should be.

The keyboard socket on the front is shocking - very easy to 
break. Mine died within the first year.

As far as I recall, the 100M was at the end of Roland 
modular production, so I doubt its circuits actually were 
used in later systems.
