"Here we have Roland's System 100m, their classic compact yet super powerful analog modular system. This set of modules is the most popular configuration that was available (known as the D-set) and includes the 150 Sample & Hold / LFO / Ring Mod, 112 Dual VCO, 121 Dual VCF, 130 Dual VCA, and 140 Dual Envelope / LFO. Of course these modules are not simply limited to their listed functions and include several convenient 'extras' such as 3 channel mixers built in for audio and CV inputs and well thought out duplicates and attenuated options for certain outputs. 
"For your consideration is a good condition Roland System 100m 4 cabinet modular synthesizer system. If you've been dreaming of getting a big 100m system and want to skip the waiting game of finding cabinets & modules, here's your chance to get the whole caboodle.
The 100M is unique from other modulars in that it has a integrated signal path for CV, Trig and Gate which be used without (or with minimal) patching.
"The System 100m is Roland's contribution to professional analog modular synthesis. It was based on the more limited, semi-modular System 100, but is several steps of ahead of its predecessor. The System 100m offers over 20 modular components to pick and choose to design a custom modular set-up. The Main unit is the M-110 which has a single VCO oscillator, VCF, and VCA section. You can then build upon this system adding any number and configurations of the various other modules which include dual VCOs, ring modulators, dual VCFs, eq, dual VCAs, dual envelopes, LFOs, various effects, mixers, sequencers, and control interfaces including 3 different keyboard controllers.
Modules are assembled into racks. The System 100m has 3 rack sizes, the M-190 holds 3 modules, the M-191 and M-191J hold 5 modules. Each rack provides the necessary 8-pin DIN power connectors and internal CV/gate connections between the modules. You still need to do some external patching, however, to send your signal through the modules of your choice to create any sounds. As for sounds, the System is basically monophonic, unless you get several racks of them for lots and lots of money! Its sound is not as warm as the System 100 before it, but it offers much more capability"

Four original DIN power cables come with the rack, as does one contemporary replacement. Five original, working Roland patch cables (varying lengths, red and black) are also part of the package.
