There's a System 700 here for restoration. One cabinet's done, and it's pretty much the equivalent of the contents of a 2600.
My husband and I played around with it yesterday. I had a blast! :)
In my opinion, the System 700 is Roland's answer to both the 2600 and a Moog Modular.
I think that's why I love playing with one so much! :)
Can't wait until the rest of it is done. I've been looking at that sequencer quite longingly for ages!
Oh... and my favorite module? The one that has both noise and ring modulation. ;-)
