Roland System 100m

via this auction.

Details:
112 Dual VCO
This module contains two independent VCOs with expanded features; both have a range from 32' to 2', three modulation inputs, and a sync input and output. Three waveforms are available, as is Pulse Width Modulation. These VCOs are pretty stable, with a very wide range. If they are cross-synced at their higher ranges, they make a nice impersonation of FM synthesis

121 Dual VCF
Each VCF is a -24dB/octave low pass type with a built-in, fixed, high-pass filter that's switchable between three cut-off frequencies. Each VCF has cut-off frequency resonance sliders that can send them into oscillation. With a beautiful high end and a gut-rumbling low end, these VCFs sound incredibly rich and musical compared to most digitally generated filters. Use two in series, set to a different cut-off frequency, for an even deeper effect

130 Dual VCA
Each VCA can be switched between linear and exponential modes for different amplitude curves and percussive effects when used with the EG. Each has an initial gain control, which also allows the VCAs to be used without a modulation input

140 Dual EG + LFO
This module provides two ADSR EGs and a single LFO (with five selectable waveforms)

110 VCO/VCF/VCA
This module contains the three main synthesizer elements, and when combined with a Model 140 module, provides all that is needed for the production of one synthesizer voice. This arrangement is particularly convenient in a computer controlled system where the generation of each voice in a composition can be assigned primarily to one module. The connections for signal flow from the VCO, through the VCF to the VCA are made internally to save patching time. Another internal connection allows a single envelope generator input to control both the VCF and VCA. All internal connections are made with switching jacks so that they can be broken, if desired.

191-J Five Module Rack
Originally, the racks came as self-assembly units. The rack contains the power supplie, connectors and front-panel 36-jack patchbay. The front panel also featured two pairs of lined mini and standard jack sockets that are connected to two phono sockets at the rear. The sockets on the rear of the racks often get overlooked but can be very useful for linking signals to other racks and saving on patch cords
