"Roland System 100 Full Set + boxes + cables + manuals!

Collectors condition and fully working Sys100
Probably the only system as nice and as complete left in the world...

All is there:
- System 101 Keyboard / Synth
- System 102 Expander
- System 103 Mixer with spring reverb
- System 104 Sequencer up to 1x24 or 2x 12 step
- System 109 Speakers 2x

- Full set of manuals
- Both Patch books for the 101 and 102, example patches
- Both Patch notes for the 101 and 102, empty sheets
- Patch cords, what I believe to be original Sys100 cables
- Speaker cables, what I believe to be original Sys100 cables
- Also the original piece of hardboard to attach under the Sys102 to prevent it from tipping


This has spent most of its life in a closet until I saved it years ago. I had everything serviced back then and it has been nice and stable since.
Fun to play and nice to have the system complete and use it as one instrument.
The sound of 70-ties Roland analog is unmatched, warm and rich. Sequencer nice and intuitive, Mixer is a coloring device of itself, has built in spring reverb and inputs for external (space) echo. VU-meter lights work of course."

"This is a custom built synth made for me by Jos Van Ras who is an ex-Phillips engineer in the Netherlands who builds Elektor modules and cases.

The synth consists of the following modules: 3 x VCO - very powerful VCOs with a Moog vibe and unlike most Elektors, these have Sync inputs and the sync sound is really powerful. 3 x VCF - 3 different VCFs, two based on the original Elektor designs (a 12dB multiode filter, and another filter switchable between 24/18/12/6 dB/octave with LP and HP outputs) and a third based on the Steiner Parker filter which is really nice sounding. 1 x triple LFO - 3 simple LFOs without voltage control but with a variety of waveshapes. 1 x NOISE / RANDOM VOLTAGE 4 x ADSR 2 x VCA 2 x MIXER 1 x quadruple MULTIPLES 1 x RING MOD 1 x S&H / Inverter 1 x COM which is an output module with a 3 band EQ which is surprisingly useful 1 x MIDI to CV converter

This synth offers tremendous bang for the buck, I think it gives quite a Moog feeling in sound. It contains everything you need for a great variety of sounds but you can always patch it with Eurorack or other modular gear. I will post some sound examples as there aren't many good demos online.

The negatives are that the cabinet is just functional MDF, no fancy timber, and the MIDI interface is very basic. I usually use a Kenton for more complex MIDI control."

"Teisco Synthesizer 110F in amazing condition for its age. Rare synth and even more rare in this condition. This was well kept into its original box. Fully serviced with the best care and components. Comes also with its original dust cover.

This synth runs on 100V, a step down transformer (not included) is recommended for liability to use it in your country."

Pics of the inside below.

"Now this is a beautiful and very rare gem that you will almost never see for sale; This true analog and unique member of the Roland TR family is very cool: it has lots of adjustable trims inside so shape your drum sounds, like inside the CR-78! This also makes this the perfect vintage Roland moddable analog drum machine. Also: individual outs is easy on this one.

This one is of course after not mint anymore after 50 years, but honestly; despite a few wood flaws it actualy looks very nice still, certainly comparing to other units I have seen.

On the technical side: it works for the most part. On the main output everything seems normal, besides the volume balance seems not entirely accurate, but I have nothing useful to compare. The internal speaker does'nt seem to pass the bass drum. The speaker has been disconnected before for shipping [because not all countries accept speakers being shipped the quick way], maybe something was not re-attached properly. Therefor is sold as 'kind of working but needs technical service'. So sold AS-IS. No returns or [partly] refunds if anything other then described is not working properly. Maybe I am over-accurate here, just want to tell an honest story where others just hope for the best advertising crap as 'in good condition'. Hope you appreciate it!

Volume is rewireable to 120v, its now set to 100V. I have never seen this unit on European voltage to be honest. For all higher voltages you need a simple step down transformer. Or give it a new replacemnet transformer when you are servicing this beast."
